Question

我正在使用ReportViewer，我正在寻找出口的结果。我想得到一个关于导出细节（文件名和文件路径）的回调。我google了，只能找到reportviewer.export事件，但这是在导出之前触发的事件。之后我正在寻找一些东西。任何提示将非常感谢。

您可以实施自己的ReportExport事件，以便在导出后添加功能。

这是VB.NET中的一个例子：

Private Sub ReportViewer1_ReportExport(sender As Object, e As Microsoft.Reporting.WinForms.ReportExportEventArgs) Handles ReportViewer1.ReportExport

    e.Cancel = True 'stop the default ReportExport event

    Dim strExtension As String = ""

    Select Case UCase(e.Extension.Name)

        Case "PDF"
            strExtension = ".pdf"

        Case "EXCEL"
            strExtension = ".xls"

        Case "WORD"
            strExtension = ".doc"

    End Select

    Dim dlgSaveFile As New System.Windows.Forms.SaveFileDialog

    dlgSaveFile.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)
    dlgSaveFile.Filter = e.Extension.LocalizedName + " (*" + strExtension + ")|*" + strExtension + "|All files(*.*)|*.*"

    If dlgSaveFile.ShowDialog(Me) = Windows.Forms.DialogResult.OK Then

        Me.ReportViewer1.ExportDialog(e.Extension, e.DeviceInfo, dlgSaveFile.FileName)

        'add here your functionality, for example a simple MsgBox that display where file is saved
        MsgBox("File saved in: " & dlgSaveFile.FileName)

    End If

End Sub
