WYSIWYG-editor saying that a ScriptManager is not present when it is; throws an exception

Hey Guys,

I'm new to the AJAX Toolkit, so pardon me if my problem seems a bit dumb.

WYSIWYG Exception

As you can see in this image, I have a ScriptManager on the page, so I don't have a hot clue of what's really causing the problem. My HTML is all valid, and I can actually run the page through the built-in server and it works just fine.

Anyone have any ideas?

I'm not so sure but I think this could be caused by a wrong reference to the library that ajax uses (the Web.Extentions).

Try to remove the scriptmanager and just drag a new ScriptManager from the ToolBox to the top of the webpage. Then save the page, close it, and reopen it. Normally the design-view should render normally now.

I hope this helps!

Greets,
Wim
