Beispiele

Im folgenden Codebeispiel wird veranschaulicht, wie Sie mit der BorderWidths Methode der DataGridViewCell Klasse, um die verfügbare Zeichenbereich in einer Zelle bestimmt.The following code example demonstrates how to use the BorderWidths method of the DataGridViewCell class to determine the available drawing area in a cell. Dieses Codebeispiel ist Teil eines umfangreicheren Beispiels Vorgehensweise: Deaktivieren von Schaltflächen in einer Schaltflächenspalte im der Windows Forms-DataGridView-Steuerelement.This code example is part of a larger example provided in How to: Disable Buttons in a Button Column in the Windows Forms DataGridView Control.

Hinweise

Die Standardbreite des Rahmens Zelle beträgt ein Pixel.The default width of the cell border is one pixel. Verwenden Sie die folgenden DataGridViewAdvancedCellBorderStyle Werte die Breite des Rahmens geändert:Use the following DataGridViewAdvancedCellBorderStyle values to modify the width of the border:

Darüber hinaus, wenn die DividerHeight -Eigenschaft festgelegt ist, für die Zelle, Zeile besitzt die, die Höhe des Rechtecks erhöht den Wert der DividerHeight.In addition, if the DividerHeight property is set for the cell's owning row, the rectangle's height is increased by the value of DividerHeight. Wenn die DividerWidth Eigenschaft wird festgelegt, für die besitzende Spalte von der Zelle, die durch den Wert der Breite des Rechtecks erhöht DividerWidth.If the DividerWidth property is set for the cell's owning column, the rectangle's width will be increased by the value of DividerWidth.
