Hello,
I'm trying to databind RadGrid control using method provided on this page:

http://www.telerik.com/help/aspnet-ajax/mvc-radgrid-databinding.html

    
            <% 
        
               RadGrid1.DataSource = ViewData["Customers"]; 
        
               RadGrid1.DataBind(); 
        
            %> 
        
            <telerik:RadGrid runat="server" ID="RadGrid1" AutoGenerateColumns="false"> 
        
            ....

but when I try to run it I'm getting this error:

    
            Script controls may not be registered after PreRender. 
        
            Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 
        
            Exception Details: System.InvalidOperationException: Script controls may not be registered after PreRender.

on the line with .....DataBind();

in web.config I have in <handlers>:

    
                        <add path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" validate="false"/> 
        
                        <add path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" verb="*" validate="false"/> 
        
                        <add path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" validate="false"/> 
        
                        <add path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.RadUploadProgressHandler" verb="*" validate="false"/> 
        
                        <add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false"/>

and in <httphandlers>:

    
                        <add name="ChartImage_axd" path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" preCondition="integratedMode,runtimeVersionv2.0"/> 
        
                        <add name="Telerik_Web_UI_SpellCheckHandler_axd" path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" verb="*" preCondition="integratedMode,runtimeVersionv2.0"/> 
        
                        <add name="Telerik_Web_UI_DialogHandler_aspx" path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" preCondition="integratedMode,runtimeVersionv2.0"/> 
        
                        <add name="Telerik_RadUploadProgressHandler_ashx" path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.RadUploadProgressHandler" verb="*" preCondition="integratedMode,runtimeVersionv2.0"/> 
        
                        <add name="Telerik_Web_UI_WebResource_axd" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" preCondition="integratedMode,runtimeVersionv2.0"/>

and in my MasterPage file I use RadScriptManager

EDIT. It started working when I copied exactly RadGrid from this site:

http://www.telerik.com/help/aspnet-ajax/mvc-radgrid-databinding.html

instead of using my RadGrid which I thought is "MVC friendly".
