Hi friends
Is there any way (something like event) to find out changing the value of a column that expression property set for it.
 
I think that the ColumnChanged event of the DataTable should be your best bet. That occurs after the value has changed. If you want notification before the change is committed then handle ColumnChanging instead.
 
Thanks
I test your way just now , but ColumnChanged or ColumnChanging events don't occur when an expression set for column.
This is the list of events that I test :

1-DataTable.ColumnChanging
2-DataTable.Column changed
3-Dgv.CellValueChanged
