Hello everyone.
I'm using a Window on my page that has a Rotator in it. The Rotator is bound to a LINQ data set. It worked fine,
but then I tried to put an AJAX Loading Panel to show a "loading" image while the rotator is bound and I get the following error:
The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
I tried using a RadCodeBlock without luck.
Here is my code:
(Main .aspx page)
<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">
<script type="text/javascript">
//<![CDATA[
function openWin()
{
var oWnd = radopen("SCARLog.aspx", "RadWindow1");
}
//]]>
</script>
</telerik:RadScriptBlock>
<telerik:RadWindowManager ID="RadWindowManager1" ShowContentDuringLoad="false" VisibleStatusbar="false"
ReloadOnShow="true" runat="server" Skin="Hay" EnableShadow="true">

<telerik:RadWindow ID="RadWindow1" runat="server" Behaviors="Close" NavigateUrl="Log.aspx">

Could you please try using RadWindows Content container, as shown in the following online demo: http://demos.telerik.com/aspnet-ajax/window/examples/internalcontent/defaultcs.aspx?
Kind regards,
