Remarks
This method enables derived classes to modify the contents of the cell before it enters edit mode. This method is invoked from DataGridCell (instead of DataGrid) when it has entered edit mode.
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnPreparingCellForEdit method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors
When overriding OnPreparingCellForEdit(DataGridPreparingCellForEditEventArgs) in a derived class, be sure to call the base class' OnPreparingCellForEdit(DataGridPreparingCellForEditEventArgs) method so that registered delegates receive the event.
