Question

我正在尝试获取DrillThrough事件，以在Final_GenralStatment_Total.rdlc报告中显示链接的报告，但是却收到以下错误消息：

“尚未为数据源'DataSet1'提供数据源实例。“

这是我的ASP完整代码页：

Imports Microsoft.Reporting.WebForms

公共类F声明继承System.Web.UI.Page

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

End Sub

Protected Sub ReportViewer1_Drillthrough(sender As Object, e As DrillthroughEventArgs) Handles ReportViewer1.Drillthrough

    Try
        Dim report As LocalReport = CType(e.Report, LocalReport)
        'Dim ds As DataSet = New DataSet()
        Dim dt As DataTable = New DataTable()
        Dim adp As New INV_INDDataSetTableAdapters.Final_GSInterestTotalsTableAdapter
        Dim rds As ReportDataSource = New ReportDataSource("DataSet1", dt)
        ReportViewer1.LocalReport.DataSources.Add(rds)
    Catch ex As Exception
        Throw
    End Try


End Sub

结束班级

以及完整的html页面：

感谢您的帮助。

也许您想尝试一下：

Protected Sub ReportViewer1_Drillthrough(sender As Object, e As Microsoft.Reporting.WebForms.DrillthroughEventArgs) Handles ReportViewer1.Drillthrough

    Dim lclRep As LocalReport = CType(e.Report, LocalReport)

    Dim adp As New Pension.INV_INDDataSetTableAdapters.Final_GSInterestTotalsTableAdapter
    Dim rds As New ReportDataSource("DataSet1", CType(adp.GetData(), DataTable))

    lclRep.DataSources.Add(rds)

End Sub

此外，您可能想看看这个tutorial（不幸的是使用C＃）。

如何从ReportViewer DrillThrough事件显示来自ASP.net的详细报告？
