Beispiele

Im folgenden Codebeispiel wird die Verwendung dieser Eigenschaft in einem DataGridView Steuerelement veranschaulicht, das in erster Linie für die Anzeige vorgesehen ist.The following code example illustrates the use of this property in a DataGridView control intended primarily for display. In diesem Beispiel wird das visuelle Erscheinungsbild des Steuer Elements auf verschiedene Weise angepasst, und das Steuerelement ist für eingeschränkte Interaktivität konfiguriert.In this example, the visual appearance of the control is customized in several ways and the control is configured for limited interactivity. Dieses Beispiel ist Teil eines größeren Beispiels, das in der DataGridViewCellStyle Übersicht über die-Klasse verfügbar ist.This example is part of a larger example available in the DataGridViewCellStyle class overview.

Hinweise

Wenn die Neupositionierung von Spalten aktiviert ist, können Benutzer eine Spalten Kopfzeile an eine neue Position ziehen.When column repositioning is enabled, users can drag a column header to a new position. Beachten Sie, dass fixierte und nicht fixierte Spalten zwei separate Gruppen bilden. Benutzer können Spalten innerhalb einer Gruppe neu positionieren, aber keine Spalte aus einer Gruppe in die andere verschieben.Note that frozen and unfrozen columns form two separate groups; users can reposition columns within a group, but cannot move a column from one group to the other.

Hinweis

Das DataGridView -Steuerelement unterstützt die doppelte Pufferung nicht.The DataGridView control does not support double buffering. Wenn DoubleBuffered in einem abgeleiteten DataGridView Steuerelement auf festgelegt ist, erhalten Benutzer keine visuellen Rückmeldung, wenn Sie die Größe von true Zeilen, Spalten oder Headern ändern oder Spalten neu anordnen.If DoubleBuffered is set to true in a derived DataGridView control, users will not receive visual feedback when resizing rows, columns, or headers or when reordering columns.
