I am not sure what I have done wrong but after adding a control and then trying to use the ..Build Control in the context menu I am getting the following error:
RadPanelBar - RadPanelBar1
There was an error rendering the controI.
'Items' could not be initialized. Details: [A] Telerik.Web.UI.RadPanelBar cannot be cast to [B] Telerrik.Web.UI.RadPanelBar. Type A originates from 'Telerik.We.UI,Version=2009.1.311.35, Culture=neutral, ........ in the context 'LoadNeither'
This is a rather large error however it just refers the different paths of the same telerik.web.ui version.
Any ideas?
