Design Time Errors

[Robert Verderber]

Is anyone having issues with the new 2009 Q2 release? I have just installed Vista (32 bit) , Visual Studio 2008, and the lastest Telerik controls on a clean machine. When I use the Telerik extension to create a new VB web project, everything works ok. When I try to add another telerik control to the webpage ( i tried a grid and a menu) I get all kinds of errors in the deisgn window. Sometimes they seem to work other times they don't. Even the script mamanger seems to error even though it had rendered just fine before I added another control. 

System.Web.UI.scriptreferenceCollection must have items of type 'System.Web.UIi.ScriptReference'. 'asp:ScriptReference' is of type 'System.Web.UIi.ScriptReference'

No runtime errors so far. Removing the script control and adding again seems to work. Just wierd. Never seen this behaviour before.

Hi Robert,

The design time errors you report appear when the Visual Studio IDE loads the Telerik.Web.UI assembly twice due to the shadow assembly mechanism.

I'm not sure of the exact reason this could happen, but you could try closing the Visual Studio IDE and running your solution again.

We will research this problem further and will try finding a fix for it the next days.
