动态生成OdysseyDLC报表,rdlc报表生成

后一个月,做了凯雷德DLC报表,首倘若叁块作用:

CRUISERDLC报表之动态变化报表,rdlc报表生成

前段时代,做了奥德赛DLC报表,主假设三块作用:

1、从DataGrid提取(包涵新型的增删改)的数据,自动生成对应的揽胜DLC报表文件(以流的款式驻存在内部存款和储蓄器中),用ReportViewer类来展现、打字与印刷、排版、预览、分页

一-一、提供三个领取大4控件数据的通用接口,然后拼接成DataTable那种网状的格子。DataGrid里修改、增添、删除等数据变动,立即联合更新到报表

2、给三个轻巧的TucsonDLC模板,提供表头的字体格式和表内部数据等体制相关的信息,然后再用DataGrid里提取的数码,生成DataTable后别的必需音讯,填充到报表里,

活动调节报表格式

三、做了一个TreeView,相当的粗略;依据报表文件名称,切换左边TreeView的Item,就加载分歧的报表,突显数据。用了有些反光的知识

 

 

第一步:依照 Report Definition Language (XC90DL) 生成对应的类和命名空间。

1、去 下载ReportDefinition2010.xsd。

在意:ReportDefinition和Visual Studio发表的有个小时差,官英特网有ReportDefinition200伍版和ReportDefinition2008版。ReportDefinition二零零七版,VS二零零六及未来才支撑;

ReportDefinition二〇〇九版,VS2010及随后帮忙。20十版,要VS2011随后才支撑。笔者的是VS2010,用ReportDefinition二〇〇八版就好。

 

2、找XML Schema Definition Tool (Xsd.exe),Windows操作系统会自带(微软会自带许多作用庞大的exe,若是开源就好了)。For more detail,please refer to:

官方网址有详细的一声令下使用表明

 Below is my CMD in administator mode:

C:Program Files (x86)Microsoft SDKsWindowsv7.0ABinx64>xsd

/c /n:RDLC  

/out:C:UsersadminDesktopRDLCReportResearch

C:UsersadminDesktopRDLCReportResearchReportDefinition.xsd

 完了,生成的是那般个标准(ReportDefinition200伍的浮动出来有玖仟行左右,ReportDefinition二零零六的及事后有10000多行,贴壹部分,样子参照上边代码)

www.weide1946.com 1using System.Xml.Serialization; /// <remarks/> [System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "2.0.50727.3038")] [System.SerializableAttribute()] [System.Diagnostics.DebuggerStepThroughAttribute()] [System.ComponentModel.DesignerCategoryAttribute("code")] [System.Xml.Serialization.XmlTypeAttribute(AnonymousType=true, Namespace="] [System.Xml.Serialization.XmlRootAttribute(Namespace="", IsNullable=false)] public partial class Report { private object[] itemsField; private ItemsChoiceType80[] itemsElementNameField; private System.Xml.XmlAttribute[] anyAttrField; /// <remarks/> [System.Xml.Serialization.XmlAnyElementAttribute()] [System.Xml.Serialization.XmlElementAttribute("Author", typeof(string))] [System.Xml.Serialization.XmlElementAttribute("AutoRefresh", typeof(uint))] [System.Xml.Serialization.XmlElementAttribute("Body", typeof(BodyType))] [System.Xml.Serialization.XmlElementAttribute("Classes", typeof(ClassesType))] [System.Xml.Serialization.XmlElementAttribute("Code", typeof(string))] [System.Xml.Serialization.XmlElementAttribute("CodeModules", typeof(CodeModulesType))] [System.Xml.Serialization.XmlElementAttribute("ConsumeContainerWhitespace", typeof(bool))] ReportDefinition.cs

 

第二步:创建RDLCGenerator类和TablixRDLCGenerator类

1、依照下载的Report Definition Language(PRADODL)和1个创立的简要的福特ExplorerDLC文件,知道ENVISIONDLC文件大旨要有哪几部分组成;然后层层嵌套创制就出来了,很简短。

2-一、Tablix是重大数据区,GotReportViewer上边的事例,DynamicMatrix和DynamicTable是依据LX570DL200五来做的,SportageDL二〇一〇从此,正是一个Tablix:

二-二、Tablix的第3数据区域: TablixHierarchyType CreateTablixColumnHierarchy()和TablixHierarchyType CreateTablixRowHierarchy()

贰-叁、对于HeaderRow和DataRow关键就在底下的两样。

www.weide1946.com 21 private LocIDStringWithDataTypeAttribute CreateTablixTextRunValue(bool isHeaderCell, string name) 2 { 3 LocIDStringWithDataTypeAttribute v = new LocIDStringWithDataTypeAttribute(); 4 v.Value = isHeaderCell ? name : "=Fields!" name ".Value"; 5 v.DataType = StringWithDataTypeAttributeDataType.String; 6 return v; 7 } CreateTablixTextRunValue

 二-肆、DataSet的名字自然要和ReportDataSource里的名字完全协作

 

HighlanderdlcGenerator的Read和Write方法相比较重大。

第三步:提取DataGrid的数据

一、主要从DataGrid提取每种Column的Width、BindingPath、Header的Content和种种单元格的数额。数据填充DataTable的Rows, BindingPath填充DataTable的Columns,

Header的Content用来作为报表Tablix的题目行。Binding帕特h,对于DataTemplate和DataGridHyperlinkColumn不精通咋个取提取数据.

 

2、dataGrid.ScrollIntoView(dataGrid.Items[rowIndex])那一个是任重(英文名:rèn zhòng)而道远。DataGrid用了一个虚构啥子来着的(名字不主要,原理轻易,Computer世界大批量拍卖品质的都以用那么些办法,

总结所谓的云啊布满式什么的),便是复用分界面显示,1个窗口里能装下的几10条RowContainer,每一遍滚动,人要探望的时候才再次提取新的要来得的数目。

如此那般提取数万条记下时,分界面不会卡,也不会占有许多内部存款和储蓄器,每趟是要来得的时候才取几10条,一丢丢取。要用,才给,只给急需的那一点。

第肆步:填充数据

关键在安装ReportViewer类的LocalReport.ReportPath 和LocalReport.DataSources那两项。

www.weide1946.com 7 /// <summary> /// 报表数据源产生变化时,及时更新展现报表控件的数量源 /// </summary> /// <param name="reportDataModel">报表数据模型基类</param> public void ResetReportData(ReportDataModel reportDataModel) { if (reportDataModel != null) { reportViewer.Reset(); reportViewer.LocalReport.DataSources.Clear(); reportViewer.Clear(); if (!reportDataModel.IsDataGrid) reportViewer.LocalReport.ReportPath = reportDataModel.福特ExplorerDLCReportPath; else { // 借使是DataGrid调换来的,直接从内部存款和储蓄器流里加载数据 if (reportDataModel.MsDataGrid != null) { reportViewer.LocalReport.LoadReportDefinition(reportDataModel.MsDataGrid); // 用完就释放掉,流所占领的具备能源 // reportDataModel.MsDataGrid.Dispose(); } } reportViewer.LocalReport.DataSources.Add(reportDataModel.ReportDataSource); reportViewer.RefreshReport(); } } ResetReportData

 

第5步:提供贰个ReportHelper类

现实拼接数据以及总计中度等,还有用另1套办法得以落成第一个效益。

1、依据DataGrid每列的宽度,按比例,重新恢复设置每列的宽窄。

www.weide1946.com 8 壹 /// <summary> 2 /// 依据DataGrid的Column的Actual Width来设置报表里对应Tablix的TablixColumn的幅度 三 /// </summary> 4 /// <param name="reportWidth">报表的总增进率</param> 5 /// <param name="widths">DataGrid的Column的Actual Width</param> 陆 /// <param name="tablixColumnWidths">重新按百分比总括的TablixColumn的上升的幅度列表</param> 柒 public static void CalcTablixColumnWidth(string reportWidth, List<double> widths, out List<string> tablixColumnWidths) 8{ 玖 double totalWidth = 0.0; 10 double originalTotalWidth = 0.0; 11List<double> rateColumnWidth = new List<double>(); 1二 string unit = reportWidth.Substring(reportWidth.Length - 2, 2); 一三 14 // 取到报表宽度字符串除去单位in或许cm的数值 15Double.TryParse(reportWidth.Substring(0, reportWidth.Length - ②), out totalWidth); 1陆 17 1八 for (int index = 0; index < widths.Count; index ) 1九 originalTotalWidth = widths[index]; 20 21 22 for (int index = 0; index < widths.Count; index ) 23 rateColumnWidth.Add(widths[index] / originalTotalWidth); 24 25 tablixColumnWidths = new List<string>(); 26 tablixColumnWidths.Clear(); 27 for (int index = 0; index < widths.Count; index ) 28 tablixColumnWidths.Add((rateColumnWidth[index] * totalWidth).ToString() unit); 29 } CalcTablixColumnWidth

2、把内部存款和储蓄器中的流读出来,生成对应的昂科雷DLC文件,作者这里没调用。所以设置LocalReport.ReportPath换到reportViewer.LocalReport.LoadReportDefinition(reportDataModel.MsDataGrid);

www.weide1946.com 9 一 /// <summary> 二 /// 把内部存款和储蓄器的流生成为rdlc文件 叁 /// </summary> 4 /// <param name="rdlc">按rdlc格式构变成功的内部存款和储蓄器流</param> 5public static void Dump奥迪Q3dlc(MemoryStream rdlc) 陆 { 7 string temp兰德CRUISERdlcPath = AppDomain.CurrentDomain.BaseDirectory @"../../../CommonReport/Templates/GeneratedDataGrid.rdlc"; 八 if (File.Exists(tempHavaldlcPath)) 九 File.Delete(temp路虎极光dlcPath); 十 1一 using (FileStream fs = new FileStream(temp途锐dlc帕特h, FileMode.Create)) 1二 { 一三rdlc.WriteTo(fs); 1肆 } 15 } DumpPRADOdlc

三、部分调用的代码——给2个简短的EvoqueDLC模板,以提供表头的书体格式和表内部数据等体制相关的消息,然后再用DataGrid里提取的数目,填充到报表里

www.weide1946.com 10 1 /// <summary> 贰 /// 将DataGrid的多少抽出出来,调换来rdlc报表,以促成对提供DataGrid的打字与印刷、预览、分页和页面布局等成效的支持三 /// 但须要提供三个rdlc报表的模板,必须回顾页眉页脚,至少一列多少和标题,以便获得多少的表头的 四 /// style和数据项的style,那一列数据项必须是首先项(且第一项的表头和数目都完好无缺提供了style) 伍 /// </summary> 陆 /// <param name="dataGrid">提供数据的DataGrid</param> 7 /// <param name="reportViewer">要加载DataGrid数据的ReportViewer</param> 8 /// <param name="rdlcModelFileName">rdlc模板的完全路线</param> 九 /// <param name="headline">报表标题</param> 10 public static void Print(this DataGrid dataGrid, CommonReport.Views.ReportViewer reportViewer, string rdlcModelFileName, string headline) 1一 { 1贰 if (!File.Exists(rdlcModelFileName)) return; 13 1肆 // 从DataGrid对应的rdlc模板里读出报表数量来 一五 Report report = null; 1六string dataSourceName = DatasetName; 一柒dataGrid.UnderOdysseydlcGenProc(reportViewer, headline, gen => 18 { 1玖report = gen.Read(rdlcModelFileName); 20 2壹 // ReportDataSource的Name应该用取DataSet的Name 2二 #region 取DataSourceName 23 24 DataGridHelper.ResetRdlcHeadline(report, headline); 25 for (int index = 0; index < report.Items.Length; index ) 26 { 27 if (report.Items[index] is DataSetsType) 28 { 29 DataSetsType dataSets = report.Items[index] as DataSetsType; 30 dataSourceName = dataSets.DataSet[0].Name; 31 break; 32 } 33 } 34 35 #endregion 3陆 }, (gen, ms, dt) => 三七 { 3捌 // 基于从DataGrid里提取的数码再一次组织rdlc文件 3九 揽胜极光dlcReportAdapter(report, gen.HeaderNames, gen.FieldNames, gen.Widths); 40 gen.Write(ms, report); 四1 return new Microsoft.Reporting.WinForms.ReportDataSource(dataSourceName) { Value = dt }; 4二 }); 肆3 } Print

4、打字与印刷的关于页面包车型大巴一些暗中同意设置(看状态)

www.weide1946.com 11壹 // 安装默许打字与印刷布局情势为“展现物理页” 二reportViewer.SetDisplayMode(DisplayMode.PrintLayout); 三reportViewer.ZoomMode = ZoomMode.Percent; 四 reportViewer.ZoomPercent = 拾0; 打字与印刷设置

5、TreeView反射那块——成效叁

www.weide1946.com 12 1 /// <summary> 2 /// TreeView上选拔的项发生变化时,依照所选TreeViewItem的Header消息和Tag里所蕴藏的音信,利用反射构造对应报表的多寡类实例 三 /// 加载报表模板,调用委托将数据传到报表的彰显控件上 肆 /// </summary> 5 /// <param name="sender"></param> 陆 /// <param name="e"></param> 柒 private void LacrossedlcTree_SelectedItemChanged(object sender, RoutedPropertyChangedEventArgs<object> e) 8 { 9 if ((sender != null) && (sender is TreeView)) 拾 { 1壹 if ((sender as TreeView).SelectedItem is TreeViewItem) 1二 { 一3 TreeViewItem tempItem = (sender as TreeView).SelectedItem as TreeViewItem; 14 if (tempItem.Tag is TreeViewItemDataType) 一5 { 1陆 TreeViewItemDataType tempTreeViewDataType = tempItem.Tag as TreeViewItemDataType; 一七 // 报表类型 1八 if (tempTreeViewDataType.UserControlType == TreeViewItemDataType.ControlType.Report) 19 { 20 string reportDataModelInstanceName = tempItem.Header "Model"; 二一 Type type = typeof(ReportDataModel); 22 Assembly assembly = type.Assembly; 二3 try 二四{ 2伍 ReportDataModel reportDataModelInstance = (ReportDataModel)assembly.CreateInstance(type.Namespace "." reportDataModelInstanceName); 26 if (reportDataModelInstance != null) 27 { 28 reportDataModelInstance.RDLCReportPath = (tempItem.Tag as TreeViewItemDataType).FullPath; 29 reportDataModelInstance.InitDataSource(); 30 if (Viewer != null) 31 Viewer.ResetReportData(reportDataModelInstance); 32 } 33 } 34 catch (Exception ex) 35 { 36 MessageBox.Show(ex.Message); 37 } 38 } 39 40 // DataGrid 类型 41 else if (tempTreeViewDataType.UserControlType == TreeViewItemDataType.ControlType.DataGrid) 42 { 43 Type type = this.GetType(); 44 Assembly assembly = type.Assembly; 45 try 46 { 47 UserControl dataGridUserControlInstance = (UserControl)assembly.CreateInstance(type.Namespace ".DataGrid." tempItem.Header); 48 } 49 catch (Exception ex) 50 { 51 MessageBox.Show(ex.Message); 52 } 53 } 54 } 55 } 56 } 57 } RdlcTree_SelectedItemChanged

六、通过VisualTreeHelper找到内定项目标子只怕父的章程,可在WPF里通用

www.weide1946.com 13 /// <summary> /// 寻觅子Visual的特定项目标Parent /// </summary> /// <typeparam name="T">钦赐项目</typeparam> /// <param name="child">承袭自Visual的中坚控件类型的子Visual</param> /// <returns></returns> public static T GetParent<T>(Visual child) where T : Visual { T parent = default(T); Visual visual = VisualTreeHelper.GetParent(child) as Visual; parent = visual as T; if (parent == null) return GetParent<T>(visual); else return parent; } /// <summary> /// 遍历取父控件的子Viusal,取到钦定项目的子Viusal /// </summary> /// <typeparam name="T">T是Visual或其子类(基本上WPF的控件都以Visual的子类),钦点子类型</typeparam> /// <param name="parent">父控件</param> /// <returns>子Viusal</returns> public static T GetVisualChild<T>(Visual parent) where T : Visual { T child = default(T); int numVisuals = VisualTreeHelper.GetChildrenCount(parent); for (int i = 0; i < numVisuals; i ) { Visual visual = (Visual)VisualTreeHelper.GetChild(parent, i); child = visual as T; if (child == null) child = GetVisualChild<T>(visual); else break; } return child; } VisualTreeHelper

七、提供一个多少深拷贝的通用方法(C#类以及除基类型之外,诸多都以传引用,这么些是地点,值拷贝倒霉搞,那个办法直接拷贝流,可是必须类的每种字段都帮忙类别化)

www.weide1946.com 14 一 /// <summary> 二 /// 对引用类型的数额——“全体字段都加了Serializable天性,以帮忙类别化” 三 /// 利用连串化和反连串化落成深度拷贝,即拷贝了堆上的数据,搞了个堆的别本 4 /// 而不是浅拷贝那样,只是拷贝了二个针对数据堆的内存地址 伍 /// 卓殊实用的小函数,补助具备引用类型数据 陆 /// </summary> 柒 /// <param name="original">要拷贝的引用类型数据源</param> 八 /// <returns>源数据的副本</returns> 9 public static object DeepColne(Object original) 10 { 1一 // 构造2个暂且的内部存储器流 1贰 using (MemoryStream ms = new MemoryStream()) 一三 { 14 // 调用BinaryFormatter来实现复杂的系列化和反系列化职业 1伍 BinaryFormatter formatter = new BinaryFormatter(); 16 1七 // StreamingContext—描述给定的连串化流的源和对象,并提供多个由调用方定义的附加上下文 1八 formatter.Context = new StreamingContext(StreamingContextStates.Clone); 1玖 20 // 把对象图系列化到内部存款和储蓄器流,original的各种字段必须标识为可连串化,不然会出错 21 formatter.Serialize(ms, original); 2二 二3 // 反系列化在此以前必要设置流的日前岗位为最早先的职位 二四 ms.Position = 0; 2伍 26 // 把内部存款和储蓄器流反连串化为目的图,再以基类的款型再次回到给调用者 二7 return formatter.Deserialize(ms); 2八 } 2九 } DeepColne

 

6、运营效果

壹、含有DataGrid或许别的控件的界面

www.weide1946.com 15

二、点击打字与印刷后,报表生成

www.weide1946.com 16

附:

1、ReportItems!具体宝马X5DLC报表上控件的名称.Value那几个取到报表设计器里任性项的数量,然后就可在表明式里开始展览各个逻辑运算。比方:

= ReportItems!forestryMaintenance.Value ReportItems!pension.Value ReportItems!SumPolicy.Value

  • ReportItems!livingExpenses.Value ReportItems!resettlement.Value

2、合并单元格,纵向和横向的

其一要分组,具体请找寻网络能源

三、调整每页都展现

对此标题,设置KeepWith属性和Tablix一同出现就好;还有贰个艺术,是设置任何的性质,目前忘了,英特网有

4、XML很关键,据最近所知,微软的工程文件、WPF、打印、报表、XPS、Office200七过后版本等,XML都以基本。(未完,待续)

5、页面纸张尺寸(PageSetting里的某个有关大小的值,单位都以10%0 inch;页面设置布局排版打印有点麻烦,稍不检点就多出去一点,字体、页眉、页脚、边框、页边距等),如下图:

 6、border style

最后,必须谢谢和致意蜡人张前辈:

二.微软GotReportViewer官方的案例:

上月,做了EvoqueDLC报表,首假如3块功效: 一、从DataGrid提取(包括新型的增加和删除改)的数额,自动生...

1、从DataGrid提取(包涵新型的增加和删除改)的数目,自动生成对应的MuranoDLC报表文件(以流的样式驻存在内部存款和储蓄器中),用ReportViewer类来突显、打字与印刷、排版、预览、分页

一-一、提供一个领到放肆控件数据的通用接口,然后拼接成DataTable那种网状的格子。DataGrid里修改、增添、删除等数据变动,即刻联合立异到报表

2、给二个简练的HighlanderDLC模板,提供表头的书体格式和表内部数据等体制相关的新闻,然后再用DataGrid里提取的数码,生成DataTable后其它必需音信,填充到报表里,

自行调解报表格式

3、做了1个TreeView,很轻便;依照报表文件名称,切换右边TreeView的Item,就加载差别的表格,呈现数据。用了几许反光的文化

 

 

第2步:遵照 Report Definition Language (揽胜极光DL) 生成对应的类和命名空间。

1、去 下载ReportDefinition2010.xsd。

留意:ReportDefinition和Visual Studio公布的有个日子差,官互连网有ReportDefinition200伍版和ReportDefinition2008版。ReportDefinition200伍版,VS贰零零捌及以往才支撑;

ReportDefinition2010版,VS20十及事后支持。20十版,要VS2013之后才支撑。笔者的是VS20十,用ReportDefinition二〇〇九版就好。

 

二、找XML Schema Definition Tool (Xsd.exe),Windows操作系统会自带(微软会自带多数功效庞大的exe,倘若开源就好了)。For more detail,please refer to:

官方网址有详尽的一声令下使用表明

 Below is my CMD in administator mode:

C:Program Files (x86)Microsoft SDKsWindowsv7.0ABinx64>xsd

/c /n:RDLC  

/out:C:UsersadminDesktopRDLCReportResearch

C:UsersadminDesktopRDLCReportResearchReportDefinition.xsd

 完了,生成的是如此个样板(ReportDefinition200伍的变迁出来有八千行左右,ReportDefinition二零一零的及事后有10000多行,贴一部分,样子参照下面代码)

www.weide1946.com 19www.weide1946.com 20

using System.Xml.Serialization;


    /// <remarks/>
    [System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "2.0.50727.3038")]
    [System.SerializableAttribute()]
    [System.Diagnostics.DebuggerStepThroughAttribute()]
    [System.ComponentModel.DesignerCategoryAttribute("code")]
    [System.Xml.Serialization.XmlTypeAttribute(AnonymousType=true, Namespace="http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition")]
    [System.Xml.Serialization.XmlRootAttribute(Namespace="http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition", IsNullable=false)]
    public partial class Report {

        private object[] itemsField;

        private ItemsChoiceType80[] itemsElementNameField;

        private System.Xml.XmlAttribute[] anyAttrField;

        /// <remarks/>
        [System.Xml.Serialization.XmlAnyElementAttribute()]
        [System.Xml.Serialization.XmlElementAttribute("Author", typeof(string))]
        [System.Xml.Serialization.XmlElementAttribute("AutoRefresh", typeof(uint))]
        [System.Xml.Serialization.XmlElementAttribute("Body", typeof(BodyType))]
        [System.Xml.Serialization.XmlElementAttribute("Classes", typeof(ClassesType))]
        [System.Xml.Serialization.XmlElementAttribute("Code", typeof(string))]
        [System.Xml.Serialization.XmlElementAttribute("CodeModules", typeof(CodeModulesType))]
        [System.Xml.Serialization.XmlElementAttribute("ConsumeContainerWhitespace", typeof(bool))]

ReportDefinition.cs

 

第二步:创建RDLCGenerator类和TablixRDLCGenerator类

一、遵照下载的Report Definition Language(HighlanderDL)和三个创制的简易的RAV四DLC文件,知道EvoqueDLC文件中央要有哪几部分构成;然后层层嵌套创立就出去了,相当粗略。

二-一、Tablix是第二数据区,GotReportViewer上面包车型地铁例子,DynamicMatrix和DynamicTable是依附奥迪Q7DL贰零零伍来做的,汉兰达DL200九事后,就是八个Tablix:

贰-2、Tablix的紧要数据区域: TablixHierarchyType CreateTablixColumnHierarchy()和TablixHierarchyType CreateTablixRowHierarchy()

贰-3、对于HeaderRow和DataRow关键就在下边包车型地铁不等。

www.weide1946.com 21www.weide1946.com 22

1         private LocIDStringWithDataTypeAttribute CreateTablixTextRunValue(bool isHeaderCell, string name)
2         {
3             LocIDStringWithDataTypeAttribute v = new LocIDStringWithDataTypeAttribute();
4             v.Value = isHeaderCell ? name : "=Fields!"   name   ".Value";
5             v.DataType = StringWithDataTypeAttributeDataType.String;
6             return v;
7         }

CreateTablixTextRunValue

 二-4、DataSet的名字自然要和ReportDataSource里的名字完全相配

 

RdlcGenerator的Read和Write方法相比关键。

第三步:提取DataGrid的数据

一、主要从DataGrid提取各类Column的Width、BindingPath、Header的Content和各样单元格的数目。数据填充DataTable的Rows, BindingPath填充DataTable的Columns,

Header的Content用来作为报表Tablix的标题行。BindingPath,对于DataTemplate和DataGridHyperlinkColumn不明白咋个取提取数据.

 

2、dataGrid.ScrollIntoView(dataGrid.Items[rowIndex])那些是首要。DataGrid用了三个虚构啥子来着的(名字不重大,原理简单,Computer世界多量处理质量的都以用那么些主意),正是复用分界面彰显,1个窗口里能装下的几10条RowContainer,每一次滚动,人要察看的时候才重新提取新的要出示的数额。

这么提取数万条记下时,分界面不会卡,也不会占用许多内部存款和储蓄器,每回是要显得的时候才取几拾条,一丝丝取。要用,才给,只给需求的那一点。

                                    string value = ((cell.Content as CheckBox).IsChecked == true) ? "是" : "否";
                                    dr[bindingPaths[columnIndex]] = value;
                                }
                                else if (cell.Content is ComboBox)
                                {
                                    dr[bindingPaths[columnIndex]] = (cell.Content as ComboBox).Text;
                                    if (!String.IsNullOrEmpty((cell.Content as ComboBox).Text)) isLastRowAllEmpty = false;
                                }
                            }
                        }

                        if (dataGrid.CanUserAddRows && (rowIndex == dataGrid.Items.Count - 1))
                        {
                            // 如果CanUserAddRows被设置为true,只有最后一行的数据都不为空(CheckBox不算作内),才把数据添加到DataTable
                            if (isLastRowAllEmpty)
                            {
                                continue;
                            }
                        }
                        dt.Rows.Add(dr);
                    }
                }
            }
        }

提取DataGrid数据

 

第6步:填充数据

首要在安装ReportViewer类的LocalReport.ReportPath 和LocalReport.DataSources那两项。

www.weide1946.com 31www.weide1946.com 32

        /// <summary>
        ///  报表数据源发生变化时,及时更新显示报表控件的数据源
        /// </summary>
        /// <param name="reportDataModel">报表数据模型基类</param>
        public void ResetReportData(ReportDataModel reportDataModel)
        {
            if (reportDataModel != null)
            {
                reportViewer.Reset();
                reportViewer.LocalReport.DataSources.Clear();
                reportViewer.Clear();

                if (!reportDataModel.IsDataGrid)
                    reportViewer.LocalReport.ReportPath = reportDataModel.RDLCReportPath;
                else
                {
                    // 如果是DataGrid转换成的,直接从内存流里加载数据
                    if (reportDataModel.MsDataGrid != null)
                    {
                        reportViewer.LocalReport.LoadReportDefinition(reportDataModel.MsDataGrid);
                        // 用完就释放掉,流所占用的所有资源
                       // reportDataModel.MsDataGrid.Dispose();
                    }
                }
                reportViewer.LocalReport.DataSources.Add(reportDataModel.ReportDataSource);
                reportViewer.RefreshReport();
            }
        }

ResetReportData

 

第四步:提供2个ReportHelper类

切实拼接数据以及计算中度等,还有用另1套办法落到实处第1个功效。

一、依照DataGrid每列的上升的幅度,按百分比,重置每列的上升的幅度。

www.weide1946.com 33www.weide1946.com 34

 1         /// <summary>
 2         /// 根据DataGrid的Column的Actual Width来设置报表里对应Tablix的TablixColumn的宽度
 3         /// </summary>
 4         /// <param name="reportWidth">报表的总宽度</param>
 5         /// <param name="widths">DataGrid的Column的Actual Width</param>
 6         /// <param name="tablixColumnWidths">重新按百分比计算的TablixColumn的宽度列表</param>
 7         public static void CalcTablixColumnWidth(string reportWidth, List<double> widths, out List<string> tablixColumnWidths)
 8         {
 9             double totalWidth = 0.0;
10             double originalTotalWidth = 0.0;
11             List<double> rateColumnWidth = new List<double>();
12             string unit = reportWidth.Substring(reportWidth.Length - 2, 2);
13 
14             // 取到报表宽度字符串除去单位in或者cm的数值
15             Double.TryParse(reportWidth.Substring(0, reportWidth.Length - 2), out totalWidth);
16 
17 
18             for (int index = 0; index < widths.Count; index  )
19                 originalTotalWidth  = widths[index];
20 
21 
22             for (int index = 0; index < widths.Count; index  )
23                 rateColumnWidth.Add(widths[index] / originalTotalWidth);
24 
25             tablixColumnWidths = new List<string>();
26             tablixColumnWidths.Clear();
27             for (int index = 0; index < widths.Count; index  )
28                 tablixColumnWidths.Add((rateColumnWidth[index] * totalWidth).ToString()   unit);
29         }

CalcTablixColumnWidth

二、把内存中的流读出来,生成对应的猎豹CS陆DLC文件,小编这里没调用。所以设置LocalReport.ReportPath换来reportViewer.LocalReport.LoadReportDefinition(reportDataModel.MsDataGrid);

www.weide1946.com 35www.weide1946.com 36

 1         /// <summary>
 2         /// 把内存的流生成为rdlc文件
 3         /// </summary>
 4         /// <param name="rdlc">按rdlc格式构造成功的内存流</param>
 5         public static void DumpRdlc(MemoryStream rdlc)
 6         {
 7             string tempRdlcPath = AppDomain.CurrentDomain.BaseDirectory   @"../../../CommonReport/Templates/GeneratedDataGrid.rdlc";
 8             if (File.Exists(tempRdlcPath))
 9                 File.Delete(tempRdlcPath);
10 
11             using (FileStream fs = new FileStream(tempRdlcPath, FileMode.Create))
12             {
13                 rdlc.WriteTo(fs);
14             }
15         }

DumpRdlc

3、部分调用的代码——给一个差不多的安德拉DLC模板,以提供表头的书体格式和表内部数据等体制相关的消息,然后再用DataGrid里提取的数码,填充到报表里

www.weide1946.com 37www.weide1946.com 38

 1         /// <summary>
 2         /// 将DataGrid的数据抽取出来,转换成rdlc报表,以实现对提供DataGrid的打印、预览、分页和页面布局等功能的支持
 3         /// 但需要提供一个rdlc报表的模板,必须包括页眉页脚,至少一列数据和标题,以便拿到数据的表头的
 4         /// style和数据项的style,这一列数据项必须是第一项(且第一项的表头和数据都完整提供了style)
 5         /// </summary>
 6         /// <param name="dataGrid">提供数据的DataGrid</param>
 7         /// <param name="reportViewer">要加载DataGrid数据的ReportViewer</param>
 8         /// <param name="rdlcModelFileName">rdlc模板的完整路径</param>
 9         /// <param name="headline">报表标题</param>
10         public static void Print(this DataGrid dataGrid, CommonReport.Views.ReportViewer reportViewer, string rdlcModelFileName, string headline)
11         {
12             if (!File.Exists(rdlcModelFileName)) return;
13 
14             // 从DataGrid对应的rdlc模板里读出报表数据来
15             Report report = null;
16             string dataSourceName = DatasetName;
17             dataGrid.UnderRdlcGenProc(reportViewer, headline, gen =>
18             {
19                 report = gen.Read(rdlcModelFileName);
20 
21                 // ReportDataSource的Name应该用取DataSet的Name
22                 #region 取DataSourceName
23 
24                 DataGridHelper.ResetRdlcHeadline(report, headline);
25                 for (int index = 0; index < report.Items.Length; index  )
26                 {
27                     if (report.Items[index] is DataSetsType)
28                     {
29                         DataSetsType dataSets = report.Items[index] as DataSetsType;
30                         dataSourceName = dataSets.DataSet[0].Name;
31                         break;
32                     }
33                 }
34 
35                 #endregion
36             }, (gen, ms, dt) =>
37             {
38                 // 根据从DataGrid里提取的数据重新构造rdlc文件
39                 RdlcReportAdapter(report, gen.HeaderNames, gen.FieldNames, gen.Widths);
40                 gen.Write(ms, report);
41                 return new Microsoft.Reporting.WinForms.ReportDataSource(dataSourceName) { Value = dt };
42             });
43         }

Print

肆、打字与印刷的有关页面的1部分暗中同意设置(看情状)

www.weide1946.com 39www.weide1946.com 40

1             // 设置默认打印布局模式为“显示物理页”
2             reportViewer.SetDisplayMode(DisplayMode.PrintLayout);
3             reportViewer.ZoomMode = ZoomMode.Percent;
4             reportViewer.ZoomPercent = 100;

打字与印刷设置

5、TreeView反射那块——作用三

www.weide1946.com 41www.weide1946.com 42

 1         /// <summary>
 2         /// TreeView上选择的项发生变化时,根据所选TreeViewItem的Header信息和Tag里所存储的信息,利用反射构造对应报表的数据类实例
 3         /// 加载报表模板,调用委托将数据传到报表的显示控件上

 5         /// <param name="sender"></param>
 6         /// <param name="e"></param>
 7         private void RdlcTree_SelectedItemChanged(object sender, RoutedPropertyChangedEventArgs<object> e)
 8         {

陆、通过VisualTreeHelper找到钦点项目标子或然父的秘技,可在WPF里通用

www.weide1946.com 43www.weide1946.com 44

        /// <summary>
        /// 找出子Visual的特定类型的Parent
        /// </summary>
        /// <typeparam name="T">指定类型</typeparam>

        /// <returns></returns>
        public static T GetParent<T>(Visual child) where T : Visual
        {
            T parent = default(T);
            Visual visual = VisualTreeHelper.GetParent(child) as Visual;
            parent = visual as T;
            if (parent == null)
                return GetParent<T>(visual);
            else
                return parent;
        }

        /// <summary>
        /// 遍历取父控件的子Viusal,取到指定类型的子Viusal
        /// </summary>

        /// <param name="parent">父控件</param>
        /// <returns>子Viusal</returns>
        public static T GetVisualChild<T>(Visual parent) where T : Visual
        {
            T child = default(T);
            int numVisuals = VisualTreeHelper.GetChildrenCount(parent);

            for (int i = 0; i < numVisuals; i  )
            {
                Visual visual = (Visual)VisualTreeHelper.GetChild(parent, i);
                child = visual as T;
                if (child == null)
                    child = GetVisualChild<T>(visual);
                else
                    break;
            }
            return child;
        }

VisualTreeHelper

7、提供三个数额深拷贝的通用方法(C#类以及除基类型之外,多数都以传引用,那一个是地点,值拷贝糟糕搞,那些主意直接拷贝流,然则必须类的每一个字段都援救体系化)

www.weide1946.com 45www.weide1946.com 46

 1         /// <summary>
 2         /// 对引用类型的数据——“所有字段都加了Serializable特性,以支持序列化”
 3         /// 利用序列化和反序列化实现深度拷贝,即拷贝了堆上的数据,搞了个堆的副本
 4         /// 而不是浅拷贝那样,只是拷贝了一个指向数据堆的内存地址
 5         /// 非常实用的小函数,支持所有引用类型数据
 6         /// </summary>
 7         /// <param name="original">要拷贝的引用类型数据源</param>
 8         /// <returns>源数据的副本</returns>
 9         public static object DeepColne(Object original)
10         {
11             // 构造一个临时的内存流
12             using (MemoryStream ms = new MemoryStream())
13             {
14                 // 调用BinaryFormatter来完成复杂的序列化和反序列化工作
15                 BinaryFormatter formatter = new BinaryFormatter();
16 
17                 // StreamingContext—描述给定的序列化流的源和目标,并提供一个由调用方定义的附加上下文
18                 formatter.Context = new StreamingContext(StreamingContextStates.Clone);
19 
20                 // 把对象图序列化到内存流,original的每个字段必须标记为可序列化,否则会出错
21                 formatter.Serialize(ms, original);
22 
23                 // 反序列化之前需要设置流的当前位置为最开始的位置
24                 ms.Position = 0;
25 
26                 // 把内存流反序列化为对象图,再以基类的形式返回给调用者
27                 return formatter.Deserialize(ms);
28             }
29         }

陆、运营效果

壹、含有DataGrid大概其余控件的界面

www.weide1946.com 47

二、点击打字与印刷后,报表生成

www.weide1946.com 48

附:

1、ReportItems!具体福特ExplorerDLC报表上控件的名称.Value那个取到报表设计器里放肆项的多寡,然后就可在表明式里张开各类逻辑运算。比方:

= ReportItems!forestryMaintenance.Value ReportItems!pension.Value ReportItems!SumPolicy.Value

  • ReportItems!livingExpenses.Value ReportItems!resettlement.Value

2、合并单元格,纵向和横向的

其一要分组,具体请寻找网络能源

3、调整每页都显示
