- alignToRight
- Boolean
Valeur indiquant s'il faut aligner le contenu de la colonne à droite. true
si le contenu doit être aligné à droite ; sinon, false
.
Remarques
La Paint méthode utilise la GetColumnValueAtRow méthode pour déterminer la valeur à dessiner dans la cellule. La PaintText méthode est appelée pour dessiner la cellule et son contenu.
