ComboBoxEdit in GridControl shows no Popup on Click

Question

I have a ComboBoxEdit in a GridControl, which is embedded in a LookUpEdit. I want that the ComboBoxEdit shows values depending on a "Id" and a converter.

My problem: I can click on the button with the arrow in the ComboBoxEdit, but then there is no opened popup. Seems like the clickevent doesn't fire? Furtheremore in debug mode i can see, that the converter does everything right, but the ComboBoxEdit doesn't show any information about the binded list.

Here is my Code:

<dxg:GridControl x:Name="PART_GridControl">
  <dxg:GridControl.Columns>
    <dxg:GridColumn Header="Column1" Width="100">
      <dxg:GridColumn.CellTemplate>
        <DataTemplate>
          <dxe:ComboBoxEdit x:Name="PART_Editor" DisplayMember="Display" ItemsSource="{Binding Path=RowData.Row.Id, Converter={local2:ListConverter}}">
          </dxe:ComboBoxEdit>
        </DataTemplate>
      </dxg:GridColumn.CellTemplate>
    </dxg:GridColumn>
    <dxg:GridColumn FieldName="something" Header="Column2" Width="130"/>
    <dxg:GridColumn FieldName="something_else" Header="Column3" Width="100"/>
  </dxg:GridControl.Columns>
  <dxg:GridControl.View>
    <dxg:TableView Name="tv_grid" AutoWidth="True" EditorButtonShowMode="ShowForFocusedRow">
    </dxg:TableView>
  </dxg:GridControl.View>
</dxg:GridControl>

Thank you for your help!

where is the popup control?? first define your popup control then assign client instance name for it(ex popup), on combo box value change trigger type below code: popup.Show();
