I am using master page in my asp.net website.
Master page contains the RadAjaxManeger control.
In the child page I am using RadAjaxManagerProxy control to handle ajax post.
I am also using RadWindowManager control in the child page.
When I add this code in my child page.
<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server" >
<AjaxSettings>
<telerik:AjaxSetting AjaxControlID="tbInvestors">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="tbInvestors" />
<telerik:AjaxUpdatedControl ControlID="lblInvestorStatus" />
<telerik:AjaxUpdatedControl ControlID="lblInvestorID" />
</UpdatedControls>
</telerik:AjaxSetting>
</AjaxSettings>
</telerik:RadAjaxManagerProxy>
I am getting this error.
The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
and IF I remove it then the pages starts working fine.
Could you please help me here.
here is my master page code
