I'm using the ItemsRequested event to databind my RadComboBox by searching the database for the Text typed in the textbox portion on the ComboBox. The only problem is, when the user initially clicks into the textbox the ItemsRequested event immediately fires so it pulls in all possible data. Is there a way to not fire this event when the user clicks into the textbox -but- still fire the event if the user clicks the down arrow on the ComboBox itself?
