public System.Drawing.Rectangle GetCellBounds (int row, int col);

member this.GetCellBounds : int * int -> System.Drawing.Rectangle

Public Function GetCellBounds (row As Integer, col As Integer) As Rectangle

Parameter

row

Int32

Die Zeilennummer der Zelle.

col

Int32

Die Spaltennummer der Zelle.

Gibt zurück

Rectangle

Ein Rectangle, das die Ecken der aktuellen Zelle bestimmt.

Beispiele

Im folgenden Codebeispiel wird die GetCellBounds -Methode verwendet, um eine Rectangle der angegebenen Zelle zurückzugeben.
