Comment créer une grille complexe

  • Article

Cet exemple montre comment utiliser un contrôle Grid pour créer une disposition qui ressemble à un calendrier mensuel.

Exemple

L’exemple suivant définit huit lignes et huit colonnes à l’aide des classes RowDefinition et ColumnDefinition. Il utilise les propriétés attachées Grid.ColumnSpan et Grid.RowSpan, ainsi que les éléments Rectangle, qui remplissent les arrière-plans de plusieurs colonnes et lignes. Cette conception est possible, car plusieurs éléments peuvent exister dans chaque cellule d’un Grid, une différence de principe entre Grid et Table.

L’exemple utilise des dégradés verticaux pour Fill les colonnes et les lignes pour améliorer la présentation visuelle et la lisibilité du calendrier. Les éléments styletés TextBlock représentent les dates et les jours de la semaine. Les éléments TextBlock sont positionnés de manière absolue dans leurs cellules par la propriété Margin, ainsi que par les propriétés d'alignement définies dans le style de l'application.
