Hello, i've been having some problems with a radgrid EnablePostBackOnRowClick event, when this grid is in a web user control.
The reference to radajaxmanager is in the page that contains this webuser control.

It seems that the event only works one time, after the grid is filled, then it makes the ajax call and stops making the row selection.
And if the page changes... well it's does not work either.

Another problem.. but not critical, is that the loading panel is not showing when in an ajax call.

this is an example i've made:

here goes the code:
Main page testform.aspx:
<%@ Page Language="vb" AutoEventWireup="false" codefile="testform.aspx.vb" Inherits="testform" %>

Problem solved... :)

I have inserted a ajaxmanagerproxy on the webuser control

<telerik:RadAjaxManagerProxy runat="server" ID="AjaxManagerProxy" > 
<AjaxSettings> 
<telerik:AjaxSetting AjaxControlID="list" > 
<UpdatedControls> 
<telerik:AjaxUpdatedControl  ControlID="list"/> 
</UpdatedControls> 
</telerik:AjaxSetting> 
</AjaxSettings> 
</telerik:RadAjaxManagerProxy>
