Remarks
Set the IsReadOnly property to true to make all cells in an individual column read-only. Set the DataGrid.IsReadOnly property to true to make all cells in the DataGrid read-only. Set the DataGridCell.IsReadOnly property to true to make an individual cell read-only. If a conflict exists between the settings at the DataGrid, column, or cell levels, a value of true takes precedence over a value of false.
