Editor button events such as this one will fire any time the editor button is affected. This means that the event will fire, not only for the specific instance of the UltraCombo but also for any object that is using the combo as an editor (an UltraGridColumn, for example). Use the Infragistics.Win.UltraWinEditors.EditorButtonEventArgs.Context property to determine the object the event applies to.
Note that this event does not apply to the DropDown button that is normally present in the combo. This event only fires for editor buttons in the ButtonsLeft or ButtonsRight collection. To determine when the standard dropdown is dropping down, use the BeforeDropDown event.
