XAML, binding Width and Height properties to the same properties of other control
- by JAG
I'm trying to create a reflection effect and it's working great except that I have to hard-code some values. This is my XAML:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="60"/>
<RowDefinition />
<RowDefinition Height="80"/>
</Grid.RowDefinitions>
<StackPanel Grid.Row="1" VerticalAlignment="Center">
<UserControl x:Name="CurrentPresenter" />
<Border Width="500" Height="200" >
<Border.Background>
<VisualBrush Visual="{Binding ElementName=CurrentPresenter}" >
<VisualBrush.Transform>
<TransformGroup>
<ScaleTransform ScaleX="1" ScaleY="-1" CenterX="500" CenterY="99" />
</TransformGroup>
</VisualBrush.Transform>
</VisualBrush>
</Border.Background>
<Border.OpacityMask>
<LinearGradientBrush StartPoint="0,0" EndPoint="0,0.6">
<GradientStop Offset="-0.6" Color="Black"></GradientStop>
<GradientStop Offset="0.6" Color="Transparent"></GradientStop>
</LinearGradientBrush>
</Border.OpacityMask>
</Border>
</StackPanel>
</Grid>
I've tried to replace Border's Width="500" and Height="200" by Width="{Binding ElementName=CurrentPresenter, Path=Width}" and Height="{Binding ElementName=CurrentPresenter, Path=Height}" but it doesn't seem to work.
Wha's wrong with this code?
UPDATE: If I set Width and Height here:
<UserControl x:Name="CurrentPresenter" Height="200" Width="500" />
It works as expected. However it doesn't work if I set those values in the UserControl XAML. Any ideas?
