We are using RadControls for ASP.NET 2.X, Q3 2007
A developer is getting this message when opeing any aspx in VS with RadControls:
Error Creating Control - RadMenu1 Unknown server tag
This is occurring for all pages with RadControls. I am not getting this error message. What could be causing this?
Thanks for your help.
Here is one aspx page giving the error (although all other pages do as well):
<%

<%

This seems to be unrelated to RadControls because the developer had other issues and had to reformat the hard drive. After that RadControls are working fine.
Thanks for your help.

Happy to hear everything works now! VS can be a huge time saver and a huge time waster when problems like this pop-up. Hope you have smooth(er) development from here out.
