I'm trying to automate the UltraComboEditor control in C#. Assuming cboViews is an instance of UltraComboEditor and Item is the text string to match, the following line successfully changes to the correct selection.

foreach (String key in new List<string>(cboViews.Items.Keys))
{
     if (cboViews.Items[key].DisplayText.Trim() == Item)
      {
                    cboViews.SelectedItem = cboViews.Items[key];
                    return;
      }
}

However, the AfterCloseUp event is not fired, which makes sense because the drop down menu is never shown. I must fire the AfterCloseUp event.

The following block of code inserted above, however, throws an ExecutionEngineException.

cboViews.DropDown(); *** Exception thrown here
cboViews.SelectedItem = cboViews.Items[key];
cboViews.CloseUp();

My assumption, based on reading through the forums, is that DropDown is being called on the wrong object. I see an EditorWithCombo property, but it is protected and internal. Any insights are welcome.
