Hi tuonglam,
Thank you for the attached project.
First you need to remove the ScriptManager instance from the Index.aspx page as otherwise you'll got error: "Only one instance of a ScriptManager can be added to the page."
Also it seems that there is a problem with binding your RadComboBox. I'll need some more time to onvestigate the issue. Meantime could you please tell me is your RadComboBox with ID RadComboBox1 bound successfully? In the database the ROUTE table to which the RadComboBox must be bound have no data. Am I missing something?

Hello,
I have the same issue, i have a radcombo within a radgrid's EditFormSettngs, and i want to show a loading panel when the combo box selection is changed. Is there a way to do it? I looked at the RequestStart and RequestEnd methods but not sure how to attach it to the combo inside the grid. Can you provde a sample please?
Thank You

Hi kavitha,
I think that this demo will be helpful in your case. Please note that the RequestStart and ResponseEnd are called from the ClientEvents in the RadAjaxManager:
Also note that in the demo the RadCalendar updates itself:
Also in the code-behind in the SelectionChanged event handler of the RadCalendar - there is a Thread sleeped for 500 ms. This is needed so that the handler is slowed and the loading animation will have enough time to appear.
Hope this helps.

Hello Shiva,
I have prepared a sample page for you, demonstrating the correct implementation of RadAjaxManager, when you need to ajaxify both RadComboBoxes.Please find it attached and give it a try at your end.
