Hi,
in my project in VisualStudio 2008 when I want to add RadToolbar, I get:

What's wrong?
Telerik Version: 2009 SP1.
Thanks.

Hi,

Could you please try to close and open the Visual Studio again? The error should disappear.
If this doesn't help, could you please send us a sample project which demonstrates the issue to examine it locally?

Restart VS doesn't help.
It's a huge project and it's very difficult to prepare a sample for You (lots inherited class, master pages...).

Hello,

Could you send us only the RadToolBar declaration to examine it locally?

Hi,

Thank you for the provided code. Unfortunately we couldn't reproduce the problem locally and we are not exactly sure what might be causing it.
Could you please review the following forum post which discusses a similar problem:

It also links a blog from microsoft:
