alignToRight
Boolean Boolean Boolean Boolean

Ein Wert, der angibt, woran der Spalteninhalt rechts auszurichten ist.A value indicating whether to align the column's content to the right. true, wenn der Inhalt am rechten Rand ausgerichtet werden soll, andernfalls false.true if the content should be aligned to the right; otherwise, false.

Hinweise

Die- GetColumnValueAtRow Methode verwendet, um den Wert zu bestimmen, der in der Zelle gezeichnet werden soll. PaintThe Paint method uses the GetColumnValueAtRow to determine the value to draw in the cell. Die PaintText -Methode wird aufgerufen, um die Zelle und ihren Inhalt zu zeichnen.The PaintText method is called to draw the cell and its contents.
