Individual columns provide the ColumnBase.AllowEditing property which allows the default behavior specified by the grid to be overridden for individual columns. By default, this property is set to 'Default'. In this instance, the column's behavior is controlled by the grid. Setting this property to 'True' or 'False' overrides the default behavior. For instance, you can set the column's ColumnBase.AllowEditing property to 'False' to prevent an end-user from changing its values.
