contextmenu and rowclick stops working on every other postback

[mabs]

I have created a usercontrol for the grid.  I am having an issue where if you select a column to order by (click the heading), after the postbakc no rowclick, contextMenu and header contextMenu will work.  However if you sort again, they do.  So on every other postback the menu will work.

I have read on another forumk about adding the id of the contextMenu to the radajaxproxymanager, however the header contextMenu has no ID, also the rowclick also has no id as it is part of the grid.  My code is below,

<telerik:RadAjaxPanel runat="server" ID="RadAjaxPanel1" LoadingPanelID="progressLoader">


        <telerik:RadGrid ID="RadGrid1"
                         runat="server"

Any help would be much appreciated

sorted, I had wrapped an ajaxPanel around the grid on userControl, was also using an radajaxmanager on the page calling the control.  Know that I have removed the ajaxPanel all is good.
