Hi,
I have closed your second thread concerning this matter. To avoid duplications and misunderstanding I would suggest to continue our conversation here.
As for the issue you experience, take a look at the attached sample showing that SelectedIndexChanged event is fired as it should when the index is changed.
If you also want to update the RadDataGrid when a button is clicked, you should add the following settings to the RadAjaxManager:
Also, what is the version of our controls that you are using?

Hello,
Try to use the technique used in the following online demo: Related RadComboBoxes. It shows related RadComboBoxes scenario were the items are requested on demand.
The Country RadComboBox makes a request for its items when the selected index of the Continent RadComboBox is changed. It uses the client event OnClientSelectedIndexChanged of Continent RadComboBox where the requestItems() method for Country
You could refer to the implementation of the aforementioned online demo for more information and the online documentation.

Hello,
Attached is an example which demonstrates how to show the AjaxLoadingPanel when the selected index of the first RadComboBox is changed.
To learn more about RadAjax you can refer to its online documentation:
[http://www.telerik.com/help/aspnet-ajax/ajx-how-it-works.html].
I hope this helps.
