DataGrid in OK-Cancel-Apply dialog (BindingGroup)

Apr 7, 2009 at 1:10 AM
My application has a configuration dialog which uses the common OK-Cancel-Apply buttons. I use a BindingGroup on the Window and call the appropriate BeginEdit/CommitEdit/CancelEdit when the buttons are clicked. That works well for all the controls in the Window except for the DataGrid.
When I change a value in the DataGrid, it changes the source (data) object on the cell end edit. For example, if in my grid I have a list of catagories and that I change the name of a category, as soon as the cell ends the editing, the category is updated (I can see it in my main window). I would like it to update the source data object only when I click OK or Apply (which calls CommitEdit on the modal Window BindingGroup).

Is there a way to do this with the DataGrid?

Thank you,
