隱藏silverlight控件和其他控件應該自動向上移動

我有一個Silverlight窗體（xaml），其中有多個控件像標籤，文本框和網格，在某些情況下，我必須隱藏一些控件，我正在通過隱藏silverlight控件和其他控件應該自動向上移動

ctrl.Visibility = Visibility.Collapsed;

它們隱藏窗體中的控件，但控件佔用的空間不會縮小。我想要的是當這些控件被隱藏時，表單的其他控件將自動向上移動。

我有同樣的問題，我可以通過把我所有的控件，我要隱藏在一個StackPanel內部做到上述。如果將控件的可見性設置爲StackPanel內部的Collapsed，那麼此面板會自動將下面的元素移至頂部。
