Hi,
I get errors when the control is created in design View modus.
In the web.config-file is the following:
<add tagPrefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.UI"/>
I have attached a screenshot, that shows the problem.
What is the problem?

Hi Simon,
Can you, please, verify that the Telerik.Web.Design.dll is copied to the bin folder of the application and is referenced from there but not from the GAC?
If this does not help, you can see a detailed list with the most common causes for such error along with the solution for them here:
