備註
如果您將 LastChildFill 屬性設定為 true ，這是預設設定，則 的最後一個 DockPanel 子項目一律會填滿剩餘的空間，而不論您在最後一個子項目上設定的任何其他擴充值。 若要將子專案停駐在另一個方向，您必須將 屬性 false 設定 LastChildFill 為 ，而且也必須在最後一個子項目上指定明確的停駐方向。
注意
畫面上 之 DockPanel 子專案的位置取決於 Dock 個別子專案的 屬性 ，以及 下這些子項目的 DockPanel 相對順序。 因此，一組具有相同 Dock 屬性值的子專案，可以視這些子系在 底下 DockPanel 的順序，以不同的方式放置在畫面上。 子順序效果的位置，因為 DockPanel 會依序逐一查看其子項目，根據剩餘的空間設定每個元素的位置。
