Telerik Rad Ajax

[kalyan gupta]

Hi @

I have a Grid and a button  inside a Telerik Rad Ajax panel.

Onclick of tht button I want only the Grid portion to be updated.

Now when I click on the button which is inside the Ajax panel, and If i keep a break point at the page load. I see that complete page life cycle re occurs. Though the page flicker is not seen.

How to avoid this?? Am I missing any condition??

The same thing can be achieved with asp:updatePanel and asp:scriptmanager. Scriptmanager exposes a property IsInAsyncPostBack which is true when there is a Ajax postback.

Is there any such property with Telerik?

Please let me know.

Thanks in advance.

Hello kalyan,

What ajax does is to turn regular postbacks into callbacks. However in both cases, postback or callback, the page lifecycle is executed the same way but only part f the page content is updated on the client.

When you are using RadAjax to ajaxify the page and ajax request is initiated, the ScriptManager IsInAsyncPostBack property should also return true. Furthermore the RadAjaxManager and RadAjaxPanel have the IsAjaxRequest property which is true in case some of the controls ajaxified with them initiated the request.
