Use the Item property to access to a specific column.  The Count property counts the columns in the control. Use the Columns property to access the control's Columns collection. The SortBarColumn / SortBarColumnsCount properties can be used to enumerate the columns in the control's sort bar. The Visible property indicates whether the column is visible or hidden. The Position property specifies the position of the column. The user can change the column's position by drag and drop, so the position of the column can be changed at runtime. Instead the Index property is a read only property that gives the index of the column in the collection.
