Only one instance of a RadAjaxManager can be added to the page

[Matt]

Hi,

I am relative new to Telerik RadControls, in fact I just started this week, I created several user controls, some of them use RadAjaxManager, if I try to use two of these controls in the same aspx page I got the error:

Only one instance of a RadAjaxManager can be added to the page!

 

What should I do?  

TIA

Hello Matt,

AJAX Manager allows only a single instance of the control on the same page. Check the following help documentation which explains more about adding AJAX Manager in WebUserControls.
RadAjax and WebUserControls.

Thanks,
