The DataGrid control calls the PrepareCellForEdit method when a cell in a column derived from DataGridColumn enters editing mode. Derived column types override this method to respond to the user gesture indicated by editingEventArgs and return the current value prior to editing.

To respond to editing mode for cells in columns derived from DataGridTemplateColumn, handle the DataGrid.PreparingCellForEdit event.
