A column’s Visible property specifies whether this column is visible. To define the column’s position among visible columns, use the VisibleIndex property.
The false value of the Visible property sets the VisibleIndex property to -1. If you change the VisibleIndex property value to non-negative, a web control sets the Visible property to true.
