Hi

I have a grid and a button outside of the grid.  My grid has 3 columns - id, name, and comment - and it is bound to an ObservableCollection and the RaisePropertyChanged event updates
the cells properly with the exception of the last cell.  For instance, I have 3 records and if I enter the comment on all 3 records and I click the button, only the first 2 comments
were saved.  But if I click on another cell, after I entered the comment on 3 records, then I can see all of them.  How can I fix this issue?  Thanks!
