Just struggling tog et a very simple RadTabStrip POC working, am now getting an error:

Control 'ScriptManager1' of type 'ScriptManager' must be placed inside a form tag with runat=server.

However when I look at the code (pasted below) it seems to me the Scriptmanager tag is very clearly inside the form tag with the runat=server tag. Can anyone offer any suggestions?

Hi John,

This works perfectly fine. Please verify that the thrown error is not on a
different page. Clean and Rebuild your project, it is possible that Visual Studio has cached the latest compiled assembly.
