Windows 8（Metro App）中的透明度

Question

I am trying to make transparent Grid but Text(or something else) on it not transparent. What i am supposed to do? And sorry for my English.

Answer 1

Per an older question, the trick to allow a child element to override the opacity is to use a brush on the parent's background instead:

  <Grid.Background>
            <SolidColorBrush Color="Black" Opacity="0.5"/>
  </Grid.Background>
