问题 I have a WPF application with MVVM pattern. In one of my view, I have to bind an ObservableCollection to view. In that view, I have one ListBox and one DataGrid both bind to the same ObservableCollection but doing different things like events, style etc..

问题 I have a WPF datagrid which works for what I want, but there are two cells in each row which can be edited. Is it possible to place both of these rows into edit mode when the row is edited, then fire the update when the row edit ends/the row loses focus?
