Datagridview Real-Time Calculation

You need to take care of this in the collection that is bound to this grid, following these guidelines:

- Create a class A to hold the data for one row, and implement INotifyPropertyChanged on it
- Create another class that has the collection of A objects as a property
- Create each instance of class A, subscribe to the PropertyChanged event of it, and add to the collection
- Recalculate the values and update the items in the collection in your PropertyChanged event handler
- Implementing INotifyPropertyChanged should make sure that your grid is refreshed automatically when you bind the collection to it.
