Remarks

The DataGrid control calls the PrepareCellForEdit method when a cell in a column derived from DataGridColumn enters editing mode. The DataGridTemplateColumn class overrides this method to return nulla null reference (Nothing in Visual Basic).

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