hi, does any body knows if i can make a Infragistics.Win.UltraWinToolbars.ComboBoxTool on a ribbon work like the youtube or google's textbox search?

ther is no problem conecting with the DB, ther is no problem iterating throw the rows and adding them to te combo:

   If Not reader.GetValue(1) Is System.DBNull.Value Then
      display = reader.GetValue(1)
   End If

   If Not reader.GetValue(2) Is System.DBNull.Value Then

      value = reader.GetValue(2)
   End If

   combobox_lug.ValueList.ValueListItems.Add(value, display)

My problem is 'expanding' or dropdown the item. does anybody knows how?
