The RadScriptManager replaces the ASP.NET script manager when setup correctly. You don't need both on the same page.

The purpose of RadScriptManager is to replace the regular asp ScriptManager and allows to combine the embedded script resources for RadControls for ASP.NET AJAX (while at the same time has the same capabilities of the MS ScriptManager control).
