How to use given event to trigger ajax-updating

[Derek Tzeng]

Dear all,

In original asp.net ajax updatepnael, We can use a Trigger tag to determine which control and event name to fire ajax's update. It's really useful when using lots of use control in a page.

For example, I have 3 user control on a page:

Control_A has two events : event_1 and event_2

event_1 will trigger Control_B's ajax updating but not Control_C

event_2 will trigger Control_C's ajax updating but not Control_B

How can I do it when using RadAjaxManager?

Thanks for your response. I have seen the articles you provide above.

However, it seems not answer my question ^^"

In these secnario, a user control marked as a AjaxControlID would fire AjaxUpdateControls' ajax-updating by any events.

What should I do if I want that AjaxUpdateControls fire ajax-updaing by a AjaxControlID's "given event"?

For example, ONLY a master grid's OnRowSelected event can trigger detail grid's ajax-updating.

Thank you

Hello Derek,

Unfortunately the desired functionality is not possible. Please note that you can ajaxify only controls that normally work with postbacks.
