Problem with AsyncUpload/Ajax Processing using MasterPage/ContentPage

[Shonda]

I am following the Demo Project

AsyncUpload / Ajax Processing

In the demo, it states to setup the RadAjax Manager as such:

    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="Thumbnail" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManager>

Since my Asych Upload control is in a Content Page, I am using an RadAjaxManagerProxy.  My problem is if I set the AjaxContorlID to the Proxy's ID, I get a javascript error that I have nested Update Panels.  If I set it to the MasterPage's RadAjaxManager ID, I get a javascript error that ID can't be found.
    
Here is my code.

MasterPage:

    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" ClientIDMode="Static"
        DefaultLoadingPanelID="ralpDefault">
        <ClientEvents OnRequestStart="centerLoadingPanel"></ClientEvents>
        <AjaxSettings>
        </AjaxSettings>
    </telerik:RadAjaxManager>

Content Page:

<telerik:RadAjaxManagerProxy ID="rampMyAccount" runat="server" ClientIDMode="Static">
    <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="rbiAvatar" />
                </UpdatedControls>
            </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManagerProxy>

Hello Shonda,

Please place your RadAjaxManager on your master page. Please consult with the following help article how to add a control to ajaxsettings.
