[Huy Truong The]

Hello,
I am using radwindow and I found the following problem:

-          I use a telerik radwindow which contains a telerik radgridview and a button .When the radwindow is opened, i click to the button and get data to fill in the radgridview. When i do that, sometimes i have the following error :

 

Error: Sys.InvalidOperationException: ManagedRuntimeError error #4004 in control 'Xaml1':

Hello,

Thanks for your support. I got the sample project of Telerik about radgridview problem. However, I can’t  open it because it uses Silverlight V3.0, not in Silverlight V2.0. So would you send me another sample project using Silverlight V2.0?

I’m looking forward to your answer. Thank you very much.
