This is awesome! I just downloaded your bits and it is working against my Silverlight 4 application. Thanks for all the hard work.

Awesome - thank you, thank you, thank you! No we can use Silverlight 4 for our prototype.

We are also planning to launch a special build of our controls against Silverlight 4. We are putting a lot of efforts in this direction and we hope to be able to launch the build in the next following days.

Most all of the controls appear to be working fine except for the RadScheduler (which is the one I need the most) and RadGridView. I am getting the following error:

Cannot create an instance of RadScheduler

Could not load type System.Windows.Data.PropertyGroupDescription from assembly System.Windows.Data, Version 2.0.5.0

Any ideas of what I am doing wrong? Thanks, Randy

Hi, Randy

I suggest you check whetherTelerik.Windows.Data.dll is refered from your project and add it if it is not . Let us known if this helps.
Randy 14 Dec 2009

It is referenced. Later I realized it's only an issue in the designer and I have it working well through source view. Thanks for getting back to me and thanks again for getting these controls out so quickly!
