RadWindow takes time to render

[Sriram]

Hi,

I have a ASPX page (parent) and a child window (child) which is a popup. When I click on the button on the parent page, the child window takes long time to render.

parent

<telerik:RadWindowManager ID="RadWindowManager1" runat="server" Overlay="false" Skin="WebBlue" OnDataBinding="RadWindowManager1_DataBinding"  >
        <Windows>
           <telerik:RadWindow ID="Search" runat="server" Width="625px" Height="650px" Modal="true" Behaviors="Close,Minimize,Maximize,Move,Pin,Resize"
                Title="Search" NavigateUrl="./SearchDialog.aspx">
           </telerik:RadWindow>
        </Windows>
    </telerik:RadWindowManager>
<asp:ImageButton runat="server" ImageUrl="~/images/Edit.gif" ToolTip="Click on search" TabIndex="2" AlternateText="Click on search" OnClientClick="return showDialog('Search')" />

child

<telerik:RadWindow>
        
<asp:Label ID="SearchLabel" Text="Search:" runat="server"></asp:Label>
            
        </telerik:RadWindow>
This code works fine on one server but does not work on another server
I am using Windows Server 2008 R2 as the OS.

This issue has been resolved. This is because, SiteMinder was blocking the webresource.axd request.
