有关那一个文件怎么利用  和 服务器端的(Sqlserver)相同 本省略....

关键在设置ReportViewer类的LocalReport.ReportPath 和LocalReport.DataSources这两项。

    //myDataSet 指的是数据源(正是你从数据Curry面查询出来的数据)

1-1、提供一个提取放肆控件数据的通用接口,然后拼接成DataTable这种网状的格子。DataGrid里改过、增添、删除等数据变动,马上联合更新到报表

  您在aspx页面上 单击ReportViewer1的右上角 选取三个本地数据源 /选拔数据源

3、调整每页都显示

  1. 在后台代码里面

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

2013年十月16日19:38:55 过了某个天 再补偿一下:

2、dataGrid.ScrollIntoView(dataGrid.Items[rowIndex])这一个是根本。DataGrid用了多个杜撰啥子来着的(名字不根本,原理轻易,Computer领域多量拍卖质量的都是用那么些法子卡塔尔国,就是复用分界面展现,二个窗口里能装下的几十条RowContainer,每回滚动,人要拜会的时候才再一次提取新的要显得的数目。

但Sqlserver二〇〇九里面未有那一个方式了 (独有接口的名称 未有达成)

1、去 下载ReportDefinition2010.xsd。

数据源使用( 第二步创设的XSD数据源 在上面会有介绍 )

官方网址有详细的一声令下使用表达

            //如何传参数

澳门新濠3559 8澳门新濠3559 9

  1. 创立八个文本夹(就比如是XSD文件夹吧)

RdlcGenerator.cs

在此个一时表里面增添列

澳门新濠3559 10澳门新濠3559 11

  1. 新创建三个aspx网页 选取ReportViewer 控件

纳瓦拉dlcGenerator的Read和Write方法相当重大。

<%@ Register Assembly="Microsoft.ReportViewer.WebForms, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
    Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %>

机动调度报表格式

引言: 以往在web项目中用到报表的时候 我们选取的是ReportServices (服务器端的)

以此表格还足以一直在网页里面调用客商端的打字与印刷机(在vs二〇〇八内部试验的)

 

     须要静心的是:引用里面增加ReportingServices WebForm 10.0版本

1、ReportItems!具体君越DLC报表上控件的名称.Value那一个取到报表设计器里猖獗项的多少,然后就可在表明式里开展各类逻辑运算。比如:

结束语:

Header的Content用来作为报表Tablix的题目行。BindingPath,对于DataTemplate和DataGridHyperlinkColumn不明了咋个取提取数据.

  <rsweb:ReportViewer ID="ReportViewer1" runat="server" Font-Names="Verdana" Font-Size="8pt"
        Height="400px" Width="400px">

    </rsweb:ReportViewer>

        /// <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();
            }
        }
  1. 风度翩翩旦不亮堂报表的数据源的称呼的话

DeepColne

<1> XSD文件的文本夹好像有必要 要是放置二个文件夹里面 就找不到 xsd数据源(不应该啊) 但是这些细节也是个经验

澳门新濠3559 12

新生 大家四个同事(李来)做的Web报表(rdlc格式) 在地头做的(Web工程里面) 未有使用Sqlserver 里面包车型大巴

(约有20来个,很详细。不常候会上持续卡塔 尔(英语:State of Qatar)

到此 就足以试运作一下您的web报表了

RdlcTree_SelectedItemChanged

在品种上 右键选取充裕/新建项 /报表 (新创建贰个rdlc文件)

2、找XML Schema Definition Tool (Xsd.exe),Windows操作系统会自带(微软会自带超多效能强盛的exe,倘若开源就好了卡塔尔。For more detail,please refer to:

1.  成立一个文件夹(就举个例证是SportageDLC文件夹吧)

 

大家报表的机动公布没有办法做了 只得张开Sqlserver 三个三个表格增加的 (忧虑...)

瞩目:ReportDefinition和Visual Studio发表的有个日子差,官方网站络有ReportDefinition二〇〇五版和ReportDefinition2008版。ReportDefinition二〇〇六版,VS2009及其后才支撑;

            ReportViewer1.LocalReport.ReportPath = @"rdlcReport1.rdlc";

<2> 报表的DLL版本的题目近年来晋级公司的二个品种(从VS二〇〇八->VS二〇一〇) 报表(ReportingServices)从8.0->10.0

3、部分调用的代码——给八个简便的奥德赛DLC模板,以提供表头的字体魄式和表内部数据等体制相关的新闻,然后再用DataGrid里提取的多寡,填充到报表里

澳门新濠3559 15

 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”

 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         }

选拔效果与利益还足以 劣势是: 须要在Sqlserver2006里面建构报表(须要 运转报表服务 设置权限等很麻烦)

1、重要从DataGrid提取每一个Column的Width、BindingPath、Header的Content和种种单元格的数码。数据填充DataTable的Rows, BindingPath填充DataTable的Columns,

4、XML很入眼,据近期所知,微软的工程文件、WPF、打字与印刷、报表、XPS、Office二〇〇六之后版本等,XML都是基本。(未完,待续卡塔尔国

    public partial class Report {

        private object[] itemsField;

        [System.Xml.Serialization.XmlElementAttribute("CodeModules", typeof(CodeModulesType))]
        [System.Xml.Serialization.XmlElementAttribute("ConsumeContainerWhitespace", typeof(bool))]

2-1、Tablix是第生机勃勃数据区,GotReportViewer上边的例证,DynamicMatrix和DynamicTable是依照EnclaveDL二零零六来做的,中华VDL2009事后,就是三个Tablix:

ReportDefinition二〇〇九版,VS二〇一〇及其后协助。二零零六版,要VS2013随后才支撑。作者的是VS二〇一〇,用ReportDefinition2009版就好。

提取DataGrid数据

第三步:提取DataGrid的数据

1、从DataGrid提取(富含新型的增加和删除改卡塔尔的多寡,自动生成对应的索罗德DLC报表文件(以流的花样驻存在内存中),用ReportViewer类来展现、打字与印刷、制版、预览、分页

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

 

具体拼接数据甚至总结高度等,还应该有用另豆蔻年华套办法贯彻第1个功能。

先是步:依据 Report Definition Language (CRUISERDL) 生成对应的类和命名空间。

对于标题,设置KeepWith属性和Tablix一同现身就好;还会有三个形式,是设置任何的品质,近来忘了,网络有

2-2、Tablix的注重数据区域: TablixHierarchyType CreateTablixColumnHierarchy()和TablixHierarchyType CreateTablixRowHierarchy()

5、TreeView反射那块——作用三

近日,做了奥迪Q5DLC报表,首要是三块功效:

澳门新濠3559,第五步:提供三个ReportHelper类

7、提供叁个数额深拷贝的通用方法(C#类以致除基类型之外,许多都以传援用,这么些是地方,值拷贝倒霉搞,那一个艺术直接拷贝流,可是必需类的每一种字段都扶植体系化卡塔尔

 

2、点击打字与印刷后,报表生成

澳门新濠3559 20澳门新濠3559 21

 2-4、DataSet的名字自然要和ReportDataSource里的名字完全相称

 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         }

2、给一个总结的KugaDLC模板,提供表头的字体魄式和表内部数据等体制相关的音讯,然后再用DataGrid里提取的数码,生成DataTable后别的必需音信,填充到报表里,

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;

6、通过VisualTreeHelper找到钦赐项指标子或许父的不二秘籍,可在WPF里通用

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

 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
 4         /// </summary>
 5         /// <param name="sender"></param>
 6         /// <param name="e"></param>
 7         private void RdlcTree_SelectedItemChanged(object sender, RoutedPropertyChangedEventArgs<object> e)
 8         {
 9             if ((sender != null) && (sender is TreeView))
10             {
11                 if ((sender as TreeView).SelectedItem is TreeViewItem)
12                 {
13                     TreeViewItem tempItem = (sender as TreeView).SelectedItem as TreeViewItem;
14                     if (tempItem.Tag is TreeViewItemDataType)
15                     {
16                         TreeViewItemDataType tempTreeViewDataType = tempItem.Tag as TreeViewItemDataType;
17                         // 报表类型

2、合併单元格,纵向和横向的

本条要分组,具体请搜索网络能源

1、含有DataGrid或然别的控件的分界面

澳门新濠3559 30

3、做了三个TreeView,相当的轻松;依据报表文件名称,切换左边TreeView的Item,就加载差别的表格,展现数据。用了一些反光的学问

 1         /// <summary>

 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         }
    /// table + matrix = tablix
    /// Microsoft 用一个tablix来支持Table(表), Matrix(矩阵) and List(列表)这三种报表项
    /// 整合了table和matrix的功能

这么提取数万条记下时,分界面不会卡,也不会占用比相当多内部存储器,每一遍是要突显的时候才取几十条,一丝丝取。要用,才给,只给需求的那一点。

1、依据下载的Report Definition Language(SportageDL卡塔 尔(阿拉伯语:قطر‎和二个开立的精简的汉兰达DLC文件,知道TiggoDLC文件主题要有哪几部分构成;然后层层嵌套创培育出去了,极粗略。

1、遵照DataGrid每列的增长幅度,按比例,重新安装每列的上升的幅度。
