Occurs when a cell in a DataGridTemplateColumn enters editing mode.
Assembly: System.Windows.Controls.Data (in System.Windows.Controls.Data.dll)
You can handle this event to respond to a user who is attempting to edit a cell in a DataGridTemplateColumn. This event does not occur for cells in other column types. If the user attempts to edit a cell in other columns derived from DataGridColumn, the DataGrid control calls the column's PrepareCellForEdit method.
