Unknown Error

[reza]

hi
I have a user control that is ajaxified by RadAjaxManagerProxy ,
I've also used a ToolTipManager that is ajaxified by setting it's OnAjaxUpdate property

It works well on page , but if I put this UserControl inside a ContentTemplate of a RadWindow in RadWindowManager
like this : 
    <telerik:RadWindowManager ID="RadWindowManager1" runat="server" EnableShadow="True"
        Skin="Office2010Blue">
        <Windows>
            <telerik:RadWindow ID="ContainerBrowser" runat="server" Title="Container Browser"
                Modal="true" Behaviors="Maximize,Close,Minimize,Move,Resize">
                <ContentTemplate>
                    <uc3:SkinBrowser ID="SkinBrowser1" runat="server" SkinType="Container" /> <<-- my user control
                </ContentTemplate>
            </telerik:RadWindow>
        </Windows>
    </telerik:RadWindowManager>

I get this error : 




Cannot unregister UpdatePanel with ID 'ToolTipManager1RTMPanel' since it was not registered with the ScriptManager. This might occur if the UpdatePanel was removed from the control tree and later added again, which is not supported.

I really have no idea to fix this problem
Thank you very much for your help

Hello Reza,

What I would recommend is that you take out this RadWindow from the RadWIndowManager and place it directly in the page and not in the Windows collection. The origin of this server error lies in the fact that there are UpdatePanels in the content that you have placed in the RadWindow and they cannot be unregistered when the Windows collelction is renewed. This issues is actually not directly related to the RadWIndow and for more information about this error please examine the following KB article: http://www.telerik.com/support/kb/aspnet-ajax/window/cannot-unregister-updatepanel-with-id-updatepanelid-since-it-was-not-registered-with-the-scriptmanager.aspx.


All the best,
