Felder

Ascending Ascending Ascending Ascending 0

Sortierung vom kleinsten zum größten.Sort from smallest to largest. Beispielsweise von A bis Z.For example, from A to Z.

Descending Descending Descending Descending 1

Sortierung vom größten zum kleinsten.Sort from largest to smallest. Beispielsweise von Z bis A.For example, from Z to A.

Beispiele

Im folgenden Codebeispiel wird veranschaulicht, wie die SortDirection -Enumeration verwendet wird, um die Richtung GridView zu bestimmen, in der das-Steuerelement seine Elemente anzeigt.The following code example demonstrates how to use the SortDirection enumeration to determine the direction in which the GridView control is displaying its items. Die SortDirection -Eigenschaft GridView des-Steuer Elements wird auf seinen Wert getestet, um die Sortierrichtung zu bestimmen.The SortDirection property of the GridView control is tested for its value to determine the sort direction.

Hinweise

Die SortDirection -Enumeration wird verwendet, um die Richtung darzustellen, in der Elemente sortiert werden.The SortDirection enumeration is used to represent the direction in which items are sorted. Sie wird häufig von Eigenschaften (z. b. SortDirection die-Eigenschaft GridView der-Klasse) verwendet, um die Reihenfolge anzugeben, in der Elemente in einem-Steuerelement angezeigt werden.It is commonly used by properties (such as the SortDirection property of the GridView class) to indicate the order in which items are displayed in a control.
