Beispiele

Im folgenden Codebeispiel werden die Zellrahmen eines DataGridView angepasst, sodass ein doppelter Rahmen die inneren Zellen und die obere linke Kopfzeilenzelle von den Zeilen- und Spaltenüberschriften trennt. In diesem Beispiel wird veranschaulicht, wie die AdjustColumnHeaderBorderStyleMethoden , AdjustRowHeaderBorderStyleund und AdjustCellBorderStyle sowie die -Eigenschaft überschrieben AdjustedTopLeftHeaderBorderStyle werden. Diese Member verwenden DataGridViewAdvancedBorderStyle Objekte, um einzelne Zellränder zu ändern.

Hinweise

Mit DataGridView dem Steuerelement können Sie das Erscheinungsbild vollständig anpassen, einschließlich der Rahmen der Zellen und Header. Der DataGridView verfügt über CellBorderStyle, ColumnHeadersBorderStyleund RowHeadersBorderStyle -Eigenschaften, mit denen Sie die Darstellung des Zellrahmens festlegen können. Wenn Sie die Rahmen jedoch weiter anpassen müssen, können Sie mit der DataGridViewAdvancedBorderStyle -Klasse den Stil des Rahmens an den einzelnen Seiten der Zellen festlegen. Die LeftEigenschaften , Right, Topund Bottom von DataGridViewAdvancedBorderStyle stellen den linken, rechten, oberen und unteren Rahmen einer Zelle dar. Sie können diese Eigenschaften für die AdvancedCellBorderStyleEigenschaften festlegenDataGridView, AdvancedRowHeadersBorderStyleAdvancedColumnHeadersBorderStyleum verschiedene Darstellungen für die Ränder zwischen den Zellen zu erzeugen.

Konstruktoren

DataGridViewAdvancedBorderStyle()

Initialisiert eine neue Instanz der DataGridViewAdvancedBorderStyle-Klasse.

Eigenschaften

All	Ruft die Rahmenart für alle Rahmen einer Zelle ab oder legt diese fest.
Bottom	Ruft das Format für den unteren Rahmen einer Zelle ab oder legt dieses fest.
Left	Ruft das Format für den linken Rahmen einer Zelle ab.
Right	Ruft das Format für den rechten Rahmen einer Zelle ab.
Top	Ruft das Format für den oberen Rahmen einer Zelle ab.

Methoden

Equals(Object)	Bestimmt, ob das angegebene Objekt dem aktuellen DataGridViewAdvancedBorderStyle-Objekt entspricht.
GetHashCode()	Dient als Hashfunktion für einen bestimmten Typ.
GetType()	Ruft den Type der aktuellen Instanz ab. (Geerbt von Object)
MemberwiseClone()	Erstellt eine flache Kopie des aktuellen Object. (Geerbt von Object)
ToString()	Gibt eine Zeichenfolge zurück, die den DataGridViewAdvancedBorderStyle darstellt.

Explizite Schnittstellenimplementierungen

ICloneable.Clone()

Erstellt ein neues Objekt, das eine Kopie der aktuellen Instanz darstellt.
