[Solved] Loading panel in master page

[Matteo Beretta]

Hi, i try tu put a loading panel on a masterpage, but return me a error:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" DefaultLoadingPanelID="RadAjaxLoadingPanel1">
</telerik:RadAjaxManager>
<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" MinDisplayTime="0" Transparency="0" >
</telerik:RadAjaxLoadingPanel>
<telerik:RadAjaxPanel runat="server" ID="loadPanel" HorizontalAlign="NotSet">
      <asp:ContentPlaceHolder runat="server" ID="MainContent" />
</telerik:RadAjaxPanel>

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
