I have a grid that is within a user control. The user control is dynamically loaded into a panel from an ajaxified rad tree node click. The grid populates correctly but disappears when I attempt to page or sort by column.

I have tried adding a Rad Ajax Proxy Mgr to the user control (SInce I already have an ajax mgr in the master page), as well as attempted to ajaxify the grid from within the user control's page_load event like so:

(this.Page.Master as SecuredMasterPage).AddAjaxSetting(this.rgAutoSuggestions, this.rgAutoSuggestions);

Neither appear to be working. I have attempted to read all Telerik Documentation on the matter and believe I am following to the tee.

Note that the on need data source event is triggered on load but not after including on page or sort.

User Control Snippet:

<telerik:RadAjaxManagerProxy ID="AjaxManagerProxy1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="rgAutoSuggestions">
