WPF DataGrid source updating on cell changed

Question

I am new to the WPF ,and i use it to build a point of sale system.

I have a DataGrid control in the main window bound to an ObservableCollection

Almund is right. UpdateSourceTrigger=LostFocus will work best in you case. And as you have mentioned that your source is updating when you move to next row, that means I guess, you are using ObservableCollection to bind your DataGrid's ItemSource. Because that is what which you need to achieve what you want.

You need to add "UpdateSourceTrigger=LostFocus" to each of your columns.
