Beispiele

Im folgenden Codebeispiel wird veranschaulicht, wie sich das Festlegen von DataGridViewCellStyle Eigenschaften für mehrere Objekte auswirkt.The following code example demonstrates the effect of setting properties on multiple DataGridViewCellStyle objects. In diesem Beispiel DataGridView wird die Hintergrundfarbe der Zellen in festgelegt, BackColor indem die- DefaultCellStyle Eigenschaft für die-Eigenschaft festgelegt wird.This example sets the background color of cells in the DataGridView by setting the BackColor property on the DefaultCellStyle property. Die Hintergrundfarbe wird für abwechselnde Zeilen überschrieben, BackColor da die-Eigenschaft für AlternatingRowsDefaultCellStyle die-Eigenschaft festgelegt ist.The background color is overridden on alternating rows because the BackColor property is set on the AlternatingRowsDefaultCellStyle property. Im Beispiel Last Prepared wird auch das Format der Datumsangaben in der Spalte durch Festlegen der Format -Eigenschaft für die- DefaultCellStyle Eigenschaft der Spalte bestimmt.The example also determines the format of dates in the column named Last Prepared by setting the Format property on the column's DefaultCellStyle property.

Hinweise

Mit DataGridViewCellStyle der-Klasse können Sie Stil Informationen für DataGridView mehrere Zellen, Zeilen, Spalten, Zeilen-oder Spaltenüberschriften freigeben, um die Arbeitsspeicher Anforderungen für das Festlegen von Stileigenschaften für einzelne Zellen zu vermeiden.The DataGridViewCellStyle class lets you share style information across multiple DataGridView cells, rows, columns, and row or column headers, avoiding the memory requirements of setting style properties on individual cells. Weitere Informationen zu Klassen, die über eine-Eigenschaft des DataGridViewCellStyle Typs und deren Beziehung zueinander verfügen, finden Sie unter Zellen Stile im Windows Forms DataGridView-SteuerElement.For more information about classes that have a property of type DataGridViewCellStyle and how they relate to each other, see Cell Styles in the Windows Forms DataGridView Control.
