I am sure I am missing something obvious in the documentation, but I can't seem to find it. Is there anything built into the GridView control so I can determine if the user actaully changed the data after they entered into edit mode? I expected something in the RowEditEnded event to indicate that. I see the OldValues collection, so i know you are keeping track of the original data, but I don't want to have to write code to manually compare the new old data for every field, especially when the grid could be generated dynamically.

Hello Frank Wanicka,

If you implement the INotifyPropertyChanged Interface, you may follow up the changes of the properties. Let me know if you need any further assistance.

Hi Frank Wanicka,

Using the INotifyPropertyChanged Interface enables you to follow up the changes made in the values of the properties, without the need of subscribing to any events. I am sending you a sample project illustrating how to implement it.

I know about INotifyPropertyChanged . My question was whether there is anything built into your GridView control to determine whether the data in a row is dirty.

I'll assume the answer is no based on your response. Thanks.
