Комментарии

Если для свойства задано LastChildFill значение trueпо умолчанию, последний дочерний элемент DockPanel всегда заполняет оставшееся пространство независимо от любого другого значения закрепления, заданного для последнего дочернего элемента. To.dock дочерний элемент в другом направлении, необходимо задать LastChildFill для свойства false значение и также указать явное направление закрепления для последнего дочернего элемента.

Примечание

Положение дочерних элементов DockPanel на экране определяется свойством соответствующих дочерних элементов и относительным порядком Dock этих дочерних элементов под элементом DockPanel. Таким образом, набор дочерних элементов с одинаковыми значениями свойств Dock можно размещать по-разному на экране в зависимости от порядка этих дочерних элементов в разделе DockPanel. Дочерние эффекты упорядочения располагаются, так как DockPanel итерирует его дочерние элементы в порядке, устанавливая положение каждого элемента в зависимости от оставшегося пространства.
