Is there any way to implement a 'SelectedIndexChanging' event for a RadComboBox?
The reason is that I need to cancel the index changed event sometimes, but I cannot since the changing event is missing in RadComboBox.
I was able to extend the radcombobox so that the selectedindexchanging event fires that allows the developer to cancel the selectedindexchanged event.
This will be useful for developers using Telerik RadControls for Winforms version prior to 2010 Q2.
The attached project contains an extended custom control that inherits RadComboBox but adds new functionality of selectedindexchanging event.
The complete code for such a custom control is given below.
Your approach is correct. You can also use RadDropDownList that implements this event.
