Remarques

Si vous définissez la LastChildFill propriété truesur , qui est le paramètre par défaut, le dernier élément enfant d’un DockPanel remplit toujours l’espace restant, quelle que soit la valeur d’accueil que vous définissez sur le dernier élément enfant. Pour.docker un élément enfant dans une autre direction, vous devez définir la LastChildFill propriété sur false et spécifier également une direction d’ancrage explicite sur le dernier élément enfant.

Notes

La position des éléments enfants d’un DockPanel sur l’écran est déterminée par la Dock propriété des éléments enfants respectifs et l’ordre relatif de ces éléments enfants sous le DockPanel. Par conséquent, un ensemble d’éléments enfants avec les mêmes valeurs de propriété Dock peut être positionné différemment sur l’écran en fonction de l’ordre de ces enfants sous le DockPanel. L’ordre enfant affecte le positionnement, car le itère à travers ses éléments enfants dans l’ordre, en définissant la position de chaque élément en fonction de l’espace DockPanel restant.
