I would like a server side event (Ajax) handler be called on each key stroke in text portion of combo. Was wondering how to set up the control to do that? I know that that the behavior of TextChanged is only on form submit, but was looking for an Ajax type event.
The ItemsRequested event occurs when the EnabledLoadOnDemand property is True and the user types text into the
input field or clicks on the drop-down toggle image when the list is empty. Place the RadComboBox in AjaxPanel to ajaxify the operation.
