Binding to ActualWidth

Quick question: Is binding to ActualWidth supported?

  <StackPanel>
    <Grid ColumnDefinitions="300">
      <Button Name="Test" Content="Hello"></Button>
    </Grid>

    <Button Content="World" Width="{Binding #Test.ActualWidth}"></Button>
  </StackPanel>

The second button should have a width of 300 now, but it’s NaN instead. What am I missing out?

Use Bounds.Width instead.

Ah, I didn’t notice that one. Ok, I will close this and assign myself to that issue, hope that’s ok. Will fix asap.
