  I have a radGridView, when the radGridView SelectionChanged event fires off, I need to set a combo to IsDropDownOpen = true;  
  
  The issue is that the IsDropDownOpen property is being set but the combo will not remain dropped down when the grid selection is changed using a mouse click.
  
  The combo will remain dropped down when the grid selection is changed using the keyboard.
  
  Either selection method calls the same method to set the IsDropDownOpen property.
  
  I am using the 2011 - Q3 version of the wpf controls.
  
  Any Ideas?

  RadComboBox will automatically close its dropdown when the user clicks on other control or window and there is no easy way to workaround this behavior.

  using the same SelectionChanged event on a pair of combo's I can force the second combo to open.  What is the difference between the two scenarios?
