Hinweise

In der Regel verwenden Sie diese Methode, wenn Sie entweder einen Designer für das System.Windows.Forms.DataGrid erstellen oder ihr eigenes Steuerelement erstellen, das die Integration enthält System.Windows.Forms.DataGrid. Sie können die Methode verwenden, um zu bestimmen, ob sich der ShouldSerializeHeaderBackColor Eigenschaftswert von seinem Standard geändert hat.
