昇順で並べ替え。Sort from smallest to largest. たとえば、A から Z。For example, from A to Z.

Descending Descending Descending Descending 1

降順で並べ替え。Sort from largest to smallest. たとえば、Z から A。For example, from Z to A.

次のコード例は、 SortDirection列挙体を使用して、 GridViewコントロールがその項目を表示する方向を決定する方法を示しています。The following code example demonstrates how to use the SortDirection enumeration to determine the direction in which the GridView control is displaying its items. コントロールのプロパティは、並べ替えの方向を決定するために、その値がテストされます。 SortDirection GridViewThe SortDirection property of the GridView control is tested for its value to determine the sort direction.
