Failed to create a 'System.Type' from the text 'telerik:RadNavigationButton'

Hi,

I have installed 2011 Q2 version and from that time I'm getting the bellow error

Failed to create a 'System.Type' from the text 'telerik:RadNavigationButton'

The previous version I was using was 2010 Q3 . I'd be thankful you let me know what I should do to fix the issue.

Many thanks,
Naseem

The issue was related to a custom theme that I created based on Telerik theme . When I used the original theme , the issue fixed.

Thank you,

Hi Naseem,

I am glad that you managed to fix your issue. However, I just wanted to let you know that the RadNavigation has been obsolete for a while now. And this is why it will be better for you to update your code using the latest Silverlight navigation framework. The task is as easy as changing out classes with the built-in ones. You can read more about the Silverlight navigation here.
