[CLOSED] Unrecognized tag prefix or device filter 'ext' message

[Fahd]

Hi,
I added the Ext.net v2.1 dll to my Toolbox. When I dragged a ext.Label control to my page, it runs fine. However, it does not bring up the intellisense when i try to set it's properties and it says "Unrecognized tag prefix or device filter 'ext' " when I mouse hover over the control. I also added the Ext.net dll to the Project's Reference directory.

I am runing VS 2010.

I tried to visit this link (http://forums.ext.net/showthread.php...7346-16-1.aspx) as suggested in this thread (http://forums.ext.net/showthread.php...0-8-1-to-0-8-2) but the link is broken.

Can you please tell me how I can fix it so the intellisense will work?

Thanks in advance!

Hi @Fahd,

Yes, the link is broken and, unfortunately, I was unable to restore it.

Maybe, you need to upgrade VS 2010? I was unable to reproduce the issue with my VS 2010.

Is this thing appear on the page when you added an Ext.NET control from the Toolbox?

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
