.net - 报表查看器 Web 控件需要 Web 窗体上的 System.Web.UI.ScriptManager

Question

我试图调用在 SSRS 中创建的 .rdl 报告在 aspx 页面中调用；但我收到以下错误:

The Report Viewer Web Control requires a System.Web.UI.ScriptManager on the web form

我的代码如下，

protected void Page_Load(object sender, EventArgs e)
{
    //string query = Session["ClosedBugsResult1"].ToString();

    if(!IsPostBack)
    ReportViewer1.ProcessingMode = ProcessingMode.Remote; 
    ReportViewer1.ServerReport.ReportServerUrl = new Uri("http://localhost/reportserver"); 
    ReportViewer1.ServerReport.ReportPath = @"D:\Users\XXX\Documents\Visual Studio 2008\Projects\BugtrackerSample1\BugTrackerSample\BugTrackerSample\Report1.rdl"; 

    //ReportParameter[] param = new ReportParameter[1]; 
    //param[0] = new ReportParameter("CustomerID", txtparam.Text);
    //ReportViewer1.ServerReport.SetParameters(param);
    System.Web.UI.ScriptManager scriptManager = new ScriptManager(); 
    Page page = new Page();
    System.Web.UI.HtmlControls.HtmlForm form = new HtmlForm();
    form.Controls.Add(scriptManager); 
    form.Controls.Add(ReportViewer1); 
    page.Controls.Add(form);
    page.DataBind();  //exception here 
    ReportViewer1.ServerReport.Refresh();
}

任何帮助表示赞赏。

在报表上，从工具箱中的报表控件之前添加一个脚本管理器:打开工具箱，选择Ajax Extensions - Script Manager，然后将其拖到窗体上。使用 Visual Studio 2012，我最终得到的是表单上的以下新控件:

<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>

Visual Studio 2012 的完整详细信息位于 http://msdn.microsoft.com/en-us/library/ms252104.aspx
