我创建了 2 个报告 billa4.rdlc 和 billa5.rdlc，我想根据用户选择的组合框选项将其中一个报告加载到 reportviewer。请帮帮我。下面的代码正在加载 billa4.rdlc

Try
        Dim P2 As New ReportParameter("pbillnum", billnoprint)
        Me.DataTable1TableAdapter.Fill(Me.billdata.DataTable1, billnoprint)
        Me.ReportViewer1.LocalReport.SetParameters(New ReportParameter() {P2})
        Me.ReportViewer1.SetDisplayMode(DisplayMode.PrintLayout)
        Me.ReportViewer1.ZoomMode = ZoomMode.FullPage
        Me.ReportViewer1.RefreshReport()

    Catch ex As Exception
        MsgBox("error")
    End Try

你试过什么？不要直接从设计模式设置报表源，通过代码来实现。

可能是这样的：

if( combooption.SelectedValue = 0) Then
        Dim P2 As New ReportParameter("pbillnum", billnoprint)
        Me.DataTable1TableAdapter.Fill(Me.billdata.DataTable1, billnoprint)
        Me.ReportViewer1.ViewReport("billa4.rdlc")
        Me.ReportViewer1.LocalReport.SetParameters(New ReportParameter() {P2})
        Me.ReportViewer1.SetDisplayMode(DisplayMode.PrintLayout)
        Me.ReportViewer1.ZoomMode = ZoomMode.FullPage
        Me.ReportViewer1.RefreshReport()
else
        Dim P2 As New ReportParameter("pbillnum", billnoprint)
        Me.DataTable1TableAdapter.Fill(Me.billdata.DataTable1, billnoprint)
        Me.ReportViewer1.ViewReport("billa5.rdlc")
        Me.ReportViewer1.LocalReport.SetParameters(New ReportParameter() {P2})
        Me.ReportViewer1.SetDisplayMode(DisplayMode.PrintLayout)
        Me.ReportViewer1.ZoomMode = ZoomMode.FullPage
        Me.ReportViewer1.RefreshReport()
End if

Dim P2 As New ReportParameter("pbillnum", billnoprint) Me.DataTable1TableAdapter.Fill(Me.billdata.DataTable1, billnoprint) Me.ReportViewer2.LocalReport.ReportPath("Bill.rdlc") Me. ReportViewer2.LocalReport.SetParameters(New ReportParameter() {P2}) Me.ReportViewer2.SetDisplayMode(DisplayMode.PrintLayout) Me.ReportViewer2.ZoomMode = ZoomMode.FullPage Me.ReportViewer2.RefreshReport() 我试过了，但没用
