Providing a complex cell editor
The following example demonstrates how to change the edit template of the cell editor for the Freight column to a custom calculator control. The C# code for the Calculate method called in the buttons' Click event simply calculates the new equation and is not provided. To shorten the code, some of the Button and KeyActivationGesture declarations have been removed.
