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

Das DataGridView -Steuerelement zeigt seine Zellen mithilfe der Stile an, InheritedStyle die von der Cell-Eigenschaft angegeben werden, die Stile DataGridViewCellStylevon anderen Eigenschaften des Typs erbt.The DataGridView control displays its cells using the styles indicated by the cell InheritedStyle property, which inherits styles from other properties of type DataGridViewCellStyle. Die durch die DefaultCellStyle -Eigenschaft angegebenen Stile betreffen alle Zellen, außer wenn Sie durch die durch die folgenden Eigenschaften angegebenen Stile überschrieben werden:The styles specified through the DefaultCellStyle property affect all cells except when overridden by the styles specified through the following properties:

Weitere Informationen finden Sie unter Zellen Stile im Windows Forms DataGridView-SteuerElement.For more information, see Cell Styles in the Windows Forms DataGridView Control.

Beim Abrufen dieser Eigenschaft wird eine DataGridViewCellStyle mit Standardwerten erstellt, wenn nicht bereits auf die Eigenschaft zugegriffen wurde.When getting this property, a DataGridViewCellStyle with default values will be created if the property has not already been accessed. Dies kann zu Leistungseinbußen führen, wenn diese Eigenschaft für viele Zeilen erhalten wird.This can cause a performance impact when getting this property for many rows. Verwenden Sie nach Möglichkeit eine einzelne DataGridViewCellStyle , um diese Eigenschaft für mehrere Zeilen festzulegen.Whenever possible, use a single DataGridViewCellStyle to set this property for multiple rows. Weitere Informationen finden Sie unter Empfohlene Vorgehensweisen für das Skalieren des DataGridView-Steuerelements in Windows Forms.For more information, see Best Practices for Scaling the Windows Forms DataGridView Control.
