[Solved] RadAjaxManagerProxy Confusion

[Michael]

I'll make my example simple for now: I have a master page and in the content page, I want a radcombo to update a radgrid with AJAX.  I have the RadAjaxManager in the master (not even sure if this is necessary??)  and I'm using the proxy in the content. 

The comob ajaxifies the grid just fine.  But what I don't get, is that when I page in the grid, it uses ajax as well.  How is that?  Here's what it looks like:

    <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" InitialDelayTime="0" MinDisplayTime="1000" Transparency="1" runat="server" Height="75px"
        Width="75px">
        <img alt="Loading..." src='<%= RadAjaxLoadingPanel.GetWebResourceUrl(Page, "Telerik.Web.UI.Skins.Default.Ajax.loading3.gif") %>'
            style="border: 0px;" />
    </telerik:RadAjaxLoadingPanel>
  <telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="rdcboCategories">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl LoadingPanelID="RadAjaxLoadingPanel1" ControlID="rdgrdProducts" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManagerProxy>

Hello Michael,

The AJAX Manager instance in the MasterPage is a requirement for the proxy to AJAX-Enable the content page. The proxy just passes the AJAX settings to the manager on the master page. The manager surrounds the updated controls with UpdatePanels so you get those ajaxified as well.

I hope this clears the confusion.

All the best,
