RowValidating is not working with NewRow

[Andrew]

I use `RowValidating` event for `RadGridView`. It works fine with regular rows, but new row is not getting red when I set `e.IsValid = false;` However, error message displays properly.
What should I do to get it working?

Hi Andrew,

Does your model/object  implement the INotifyPropertyChanged interface ? If not, I would recommend you to implement it. Then all updates will happen automatically in RadGridView. 

I believe that this will resolve your problem.

I use EF, how do I implement INotifyPropertyChanged since classes are generated automatically?

Hello Andrew,

Thank you for clarifying that!

I have tested your scenario with our latest official release (Q3 2012 SP1) and everything is working as expected. For your convenience, I have attached a sample project.

Would it be possible to let me know what exactly version of RadGridView you are using?

Kind regards,
