[转]使用 WebForms ReportViewer 控件

本文转自：http://technet.microsoft.com/zh-cn/library/aa337091

 

若要查看部署到报表服务器的报表或在本地文件系统上存在的报表，您可以在 Web 应用程序中使用 WebForms ReportViewer 控件来呈现它们。

 

 

 

 

 

 

将 ReportViewer 控件添加到 Web 应用程序

  1. 使用 Microsoft Visual C# 或 Microsoft Visual Basic 创建一个新的 Microsoft ASP.NET 网站。

    - 或 -

    打开一个现有的 ASP.NET 网站并添加一个新的 Web 窗体。

  2. 在“工具箱”中找到 ReportViewer 控件。 如果“工具箱”不可见，则可以通过从“视图”菜单中选择“工具箱”来进行访问。

  3. 将 ReportViewer 控件拖到 Web 窗体的设计图面上。

    名为 reportViewer1 的 ReportViewer 控件便添加到该窗体中。

将控件添加到该窗体之后，“ReportViewer 任务”智能标记将出现，提示您选择某一报表。 如果您要查看的报表已部署到报表服务器上，则从“选择报表”下拉列表中选择<服务器报表>选项。 选择<服务器报表>选项后，将出现两个附加的属性：“报表服务器 URL”和“报表路径”。 “报表服务器 URL”是指向相应报表服务器的地址，“报表路径”是指向要呈现的报表的完整路径。 如果您想要以本地模式查看报表，则选择“设计新报表”选项以启动报表设计器或选择已是现有项目的一部分的报表。

下面的示例演示如何呈现已部署到某一报表服务器的报表。 此示例使用     AdventureWorks2012   示例报表项目随附的 Sales Order Detail 报表。

该示例使用集成的 Windows 身份验证，因此您首先必须启用模拟。 为此，将以下行插入 web.config 文件：

 
复制
<!-- Web.config file. -->
<identity impersonate="true"/>
注意注意

默认情况下，模拟处于禁用状态。
C#
VB
复制
protected void Page_Init(object sender, EventArgs e)
{
    if (!Page.IsPostBack)
    {
        // Set the processing mode for the ReportViewer to Remote
        reportViewer.ProcessingMode = ProcessingMode.Remote;

        ServerReport serverReport = reportViewer.ServerReport;

        // Set the report server URL and report path
        serverReport.ReportServerUrl =
            new Uri("http://<Server Name>/reportserver");
        serverReport.ReportPath =
            "/AdventureWorks Sample Reports/Sales Order Detail";

        // Create the sales order number report parameter
        ReportParameter salesOrderNumber = new ReportParameter();
        salesOrderNumber.Name = "SalesOrderNumber";
        salesOrderNumber.Values.Add("SO43661");

        // Set the report parameters for the report
        reportViewer.ServerReport.SetParameters(
            new ReportParameter[] { salesOrderNumber });
    }
}

下面的示例演示如何呈现作为 Windows 应用程序的一部分并且尚未部署到报表服务器的报表。

 

 

 

 

 

 

将 Sales Order Detail 报表添加到网站

  1. 打开该报表将添加到的网站。

  2. 在“网站”菜单中，选择“添加现有项”。

  3. 浏览到安装了 AdventureWorks 报表示例项目的位置。

    默认位置是 C:\Program Files\Microsoft SQL Server\100\Samples\Reporting Services\Report Samples\AdventureWorks Sample Reports。

  4. 选择 Sales Order Detail.rdl 文件并单击“添加”按钮。

    Sales Order Detail.rdl 文件现在应是该项目的一部分。

  5. 在解决方案资源管理器中右键单击 Sales Order Detail.rdl 文件，然后选择“重命名”。 将该报表重命名为 Sales Order Detail.rdlc，然后按 Enter。

    如果解决方案资源管理器不可见，则可以通过从“视图”菜单中选择“解决方案资源管理器”来将其打开。

 

以下代码示例将为销售订单数据创建一个数据集，然后以本地模式呈现 Sales Order Detail 报表。

C#
VB
复制
protected void Page_Init(object sender, EventArgs e)
{
    if (!Page.IsPostBack)
    {
        // Set the processing mode for the ReportViewer to Local
        reportViewer.ProcessingMode = ProcessingMode.Local;

        LocalReport localReport = reportViewer.LocalReport;

        localReport.ReportPath = "Sales Order Detail.rdlc";

        DataSet dataset = new DataSet("Sales Order Detail");

        string salesOrderNumber = "SO43661";

        GetSalesOrderData(salesOrderNumber, ref dataset);

        ReportDataSource dsSalesOrder = new ReportDataSource();
        dsSalesOrder.Name = "SalesOrder";
        dsSalesOrder.Value = dataset.Tables["SalesOrder"];

        localReport.DataSources.Add(dsSalesOrder);

        GetSalesOrderDetailData(salesOrderNumber, ref dataset);

        ReportDataSource dsSalesOrderDetail = new ReportDataSource();
        dsSalesOrderDetail.Name = "SalesOrderDetail";
        dsSalesOrderDetail.Value = dataset.Tables["SalesOrderDetail"];

        localReport.DataSources.Add(dsSalesOrderDetail);

        // Create the sales order number report parameter
        ReportParameter rpSalesOrderNumber = new ReportParameter();
        rpSalesOrderNumber.Name = "SalesOrderNumber";
        rpSalesOrderNumber.Values.Add("SO43661");

        // Set the report parameters for the report
        localReport.SetParameters(
            new ReportParameter[] { rpSalesOrderNumber });
    }
