1.Crate a user control or custom control that use one of the RadControls mentioned above.
2. Bind the control to a datasource of links that will point to your external pages.
3. The external pages should be located in the root of your project or its subfolder. These pages have to be physical files - aspx web pages.
In this case you should not get a trial message, since you are going to work only in the same application. Another option us using the standard ASP.NET controls that comes with .NET Framework 4.0.
All the best,
