This property is used to determine which sorting glyph appears when the column specified by the SortedColumn property has a SortMode property value of Automatic. When the column has a SortMode property value of Programmatic, you must display and hide the sorting glyph yourself through the SortGlyphDirection property. When the column has a SortMode property value of NotSortable, you can display the sorting glyph, but space is not reserved for it if the column is automatically resized.
The value of this property is not meaningful when you sort the control using custom sorting. For more information about custom sorting, see the Sort method and the SortCompare event.
