Can not undo changes after cancel edit

[Pit Pet]

Hi,

after invoke command from button:

           <telerik:RadButton  Content="Cancel"         

          Command="telerik:RadGridViewCommands.CancelRowEdit"

          CommandTarget="{Binding ElementName=nameOfRGV}" />


edit mode is canceled but values in cells are not undoing...
I use ActionAfterLostFocus="None" attribute on my gridview and in RowEditEnded event dictiorany OldValues is empty...
How can i force gridview to load old data?

I use List<MyClass> as ItemsSource for gargridview instead of ObservableCollection<MyClass>. Can it cause the problem?

I think that my source list is updated after each cell editing. I thought that source will be updated after commitedit event...

Hello Pit Pet,

Generally your business object (MyClass) should implement INotifyPropertyChanged interface in order RadGridView to reflect all values change. You could perform a simple test after CancelRowEdit command, sort RadGridView (old values should be populated). If old values are populated you could achieve this without sort with INotifyPropertyChanged interface.

Could you provide me with a little bit more information how do you perform edit (via TAB, Enter or mouse click outside the row)?
