XAF группировка веб-столбцов

Question

Если у кого-то есть работа с eXpressApp Framework (XAF), я пытаюсь сгруппировать listView по одному или двум столбцам в коллекции, веб-модуль без удачи, заранее спасибо

Private Sub SCA_ViewBy_Execute(sender As Object, e As SingleChoiceActionExecuteEventArgs) Handles SCA_ViewBy.Execute
    If SCA_ViewBy.SelectedIndex = 0 Then
        Dim listEditor As GridListEditor = TryCast((CType(View, ListView)).Editor, GridListEditor)
        If listEditor IsNot Nothing Then
            Dim gridView As GridView = listEditor.GridView

            gridView.BeginSort()
            Try
                gridView.ClearGrouping()
                gridView.Columns("Division").GroupIndex = 0
                gridView.Columns("SubDivision").GroupIndex = -1
            Finally
                gridView.EndSort()
            End Try
        End If

    ElseIf SCA_ViewBy.SelectedIndex = 1 Then

        Dim listEditor As GridListEditor = TryCast((CType(View, ListView)).Editor, GridListEditor)

        If listEditor IsNot Nothing Then
            Dim gridView As GridView = listEditor.GridView

            gridView.BeginSort()
            Try
                gridView.ClearGrouping()
                gridView.Columns("Division").GroupIndex = 0
                gridView.Columns("SubDivision").GroupIndex = 1
            Finally
                gridView.EndSort()
            End Try


        End If
    End If

End Sub

Спасибо, я нашел решение, которое работает

Private Sub SCA_ViewBy_Execute(sender As Object, e As SingleChoiceActionExecuteEventArgs) Handles SCA_ViewBy.Execute
