Remarks
The DataGrid control calls the PrepareCellForEdit method when a cell in a column derived from DataGridColumn enters editing mode. The DataGridCheckBoxColumn class overrides this method to respond immediately to the user gesture by updating the value in the hosted CheckBox control. This immediate response is necessary because a DataGridCheckBoxColumn cell enters edit mode with the same user gesture that changes the state of its hosted CheckBox.
