title: How to databind control height to another control's height?
body: <p>I'm trying to have 2 controls have the same height. Can I do it with XAML only?</p>
  
  <p>If I did something like <code>&lt;Canvas Height="{Binding Height, ElementName=AnotherControl}" /&gt;</code> it doesn't actually do anything and the height goes to zero. The Output panel doesn't complain about any binding errors so AnotherControl.Height really exists. I tried binding to ActualHeight but it doesn't do anything either.</p>
  
  <p>Anything else I missed?</p>
