    Private Sub SaveButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles saveButton.Click
        ' Following code saves the data to an XML file for loading at
        ' a later time.

        Dim saveFileDlg As SaveFileDialog = New SaveFileDialog()
        saveFileDlg.Filter = "XML File|*.xml"
        saveFileDlg.OverwritePrompt = True
        Dim dialogResult As DialogResult = saveFileDlg.ShowDialog(Me)

        If dialogResult.OK = dialogResult Then
            ' Pass in true for the includeData parameter to save the data
            ' otherwise it will only save the structure.
            '
            Me.ultraDataSource1.SaveAsXml(saveFileDlg.FileName, True)
        End If
    End Sub

    Private Sub LoadButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles loadButton.Click
        ' Following code loads previously saved data from a file.

        Dim openFileDlg As OpenFileDialog = New OpenFileDialog()
        openFileDlg.Filter = "XML File|*.xml"
        Dim dialogResult As DialogResult = openFileDlg.ShowDialog(Me)

        If dialogResult.OK = dialogResult Then
            ' Pass in true for the includeData parameter to load the data
            ' and not just the structure.
