I have some Rad controls on my form. Interacting with them does not perform form post back, but AJAX request. Nevertheless I may use RegisterClientScript to do some JavaScript after post back. But as post back is not performed, JavaScript is never executed. How can I overcome this?
I assume you're using the Telerik RadAjaxManager to ajaxify your page. Is that correct? If so, you'll find it has a convenient "ReponseScripts" collection that allows you to add JavaScript that should be fired after the Ajax operation completes. The JavaScript can be added on the server during the Ajax callback and then it will be automatically executed by the RadAjaxManager when the callback is done.
Great. I'm glad you found the solution to your problem. And if you're looking for an easier way to add ASP.NET AJAX to your pages (without all of the messy markup and trigger definitions), definitely check out the RadAjaxManager, too.
