コントロールの高さや幅にWindowの高さや幅をバインドする方法

More than 3 years have passed since last update.

Frameなんかを使っていてそのFrameのサイズが動的に変わる場合、
Frameをはめ込んでいる親ItemのサイズもFrameにつられて変わってしまう。

そんな時とりあえず親ItemのサイズはWindowのサイズに合わせたいってことがあると思いますが
こんな感じでWindowのサイズをバインドできます。

コードは幅をバインドさせてるけどHeightに変えれば高さをバインドできます。
また、AncestorTypeのx:TypeにGridを指定すればWindowじゃなくGridをバインドさせることができます。

<StackPanel Width="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}, Path=Width}">
    <Frame NavigationUIVisibility="Hidden" Name="XXXX" Content="{Binding XXXXPage}" />
</StackPanel>
