WPF Datagrid Row Editing "ENDED" event

Question

I know that WPF datagrid has "RowEditEnding" event , but I need to fire the event on after the Row has comitted to check if the newly added row is duplicated and merge the duplicated row. My datagrid has "CanUserAddRow" property set to True.

I am using EntityObservableCollection that extends ObservableCollection to synchronize my entity with the collection. So, i considered OnCollectionChanged event, but the "InsertItem" event is raise once user click on the new item place holder row, which means the object is still empty and I cant check for duplicate.

Is there anyway that I can raise the RowEditEnded event?

Thanks...

    private void dgrid_RowEditEnding(object sender, DataGridRowEditEndingEventArgs e)     {         if (this.dgrid.SelectedItem != null)         {             (sender as DataGrid).RowEditEnding -=dgrid_RowEditEnding;             (sender as DataGrid).CommitEdit();             (sender as DataGrid).Items.Refresh();             (sender as DataGrid).RowEditEnding += dgrid_RowEditEnding;         }         else Return;         //then check if the newly added row is duplicated     }

You can use UpdateSourceTrigger=PropertyChanged on the binding of the property member for the datagrid. This will ensure that when CellEditEnding is fired the update has already been reflected in the observable collection. see this post https://stackoverflow.com/a/27239243/9285072
