Grid Disappears When paging/sorting

[Andrew]

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">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="rgAutoSuggestions" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManagerProxy>

        <telerik:RadGrid ID="rgAutoSuggestions" runat="server" AllowSorting="true" AllowPaging="true"
        AutoGenerateColumns="false" PageSize="1"
         AllowCustomPaging="true" OnNeedDataSource="rgAutoSuggestions_OnNeedDataSource"

        <PagerStyle Mode="NumericPages" />
        <MasterTableView ViewStateMode="Enabled" DataKeyNames="ListingId">

                        </asp:HyperLink>

Any ideas on this one?  I still have yet to resolve the issue

Hello,

Note that after you page is ajaxified with RadAjax, you need to recreate the last loaded control on each Page.Load as described here.

Thanks Pavlina, 

I acutally just found that piece last night, I made the change and it now seems to be working.
