At the moment I'm trying to use new in Silverlight 4 IDataErrorInfo interface to handle my validation.
Unfortunately I've hit the wall with radgridview.

The full scenario is:
1. I'm using RadControls for Silverlight  Q1 2010 SP1 for Silverlight 4.
2. ItemsSource for RadGridView is OservableCollection of entities implementing both INotifyPropertyChanged and IDataErrorInfo
3. When I try to pass the invalid value in gridview cell, the grid becomes unresponsive. After debugging, I determined that events used for validation are fired almost constantly, also, the property indexer inherited from IDataErrorInfo also gets called constantly.

Does the RadGridView support validation using IDataErrorInfo?
If not, are there any plans to provide such support, preferably shortly?

Hello Szymon Wantuch,

With the next latest internal build we will introduce an improvement to editing and validation mechanism which fixes the problem. LIB assemblies will be available later today for download. Could please try your scenario with these assemblies and let me know about the result?

Kind regards,

Thank you for answer.

I have used build RadControls_for_Silverlight_4_2010_1_0430_Dev.zip to test the functionality and indeed it works great.
My problem now is the fact that I cannot use this exact build for production purposes. When can we expect next release of production ready RadControls fo Silverlight 4?

Best Regards,
SW
