Question

Why can I not add ScriptManager control or UpdatePanel to a page in Visual Studio 2010?

The drag( or double click) just fails – it seems like there is an incompatibility somewhere?

UPDATE:
This is ‘default’ install of 2010 Ultimate on Windows7, create a web application, cannot drag ScriptManager or UpdatePanel to the designer. Typing the declarations works.

The cursor changes to the [+] icon when you drag it to the right place but nothing appears to happens on ‘drop’, briefly the documents name has * appended, this quickly changes back to normal, either is saves or does an undo.

I’m assuming something is going wrong so it undos…but what is going wrong?

I think you can solve this problem easily by resetting your toolbox.
