Design-time error with RADGrid

[Bob Uva]

I'm getting a strange design-time error viewing a RADGrid in VS2008. I've attached a image of the error window. It was working fine and something I did recently caused this but I can't nail it down. What could cause this error?

Thanks,
Bob

I was able to get rid of this error by referencing the Telerik.Web.UI.dll in the Bin folder rather than the one in the Bin35 folder. They have the exact same full version. What is the difference between them?

Hi,

Bin -> Framework 2.0
Bin35 -> Framework 3.5

Please note that some Telerik control functionalities will only work under 3.5 framework (not a lot of them)
