Set the property to true to make all the cells in the DataGrid read-only. To make individual columns or cells read-only, set the DataGridColumn.IsReadOnly or DataGridCell.IsReadOnly properties. 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.
If this property is set to true while the control is in editing mode, all pending edits are discarded.
