Are you able to find solution for this i am having the same problem. In want to fire the selected index change event when the same item is selected again.

Every item in the ComboBox has an index. When the selection changes, the selected index will be different, and so the ComboBox will trigger the SelectedIndexChanged event.

To trigger the SelectedIndexChanged - server event the AutoPostBack property must be set to True. Otherwise, the ComboBox will not make a postback at all. The OnClientSelectedIndexChanged - client event triggers in all cases.

It is not possible to Trigger the event only for certain Values. The event is triggered every time the selection changes, regardless of the values.

However, you can cancel the selection for certain items. For example, you can prevent users to select a certain item from the list. That can be achieved by canceling the event in the OnClientSelectedIndexChanging - client event, thus preventing the selection change.

 

If the Combo is not working as expected, there might be exceptions on the page which you will need to investigate. Always keep an eye on the Console tab in the Browser's DevTools.

Hi Manish,

As the name suggests, the SelectedIndexChanged event fires only when the selected index of RadComboBox is changed.
Could you provide some more information on the scenario that you are trying to achieve?
