Question

I got the following xaml

<Grid>
<Grid.RowDefinitions>
  <RowDefinition Height="Auto" />
  <RowDefinition Height="Auto" />
</Grid.RowDefinitions>

<TextBlock x:Name="_sampleText"
           Grid.Row="0"
           VerticalAlignment="Stretch" 
           HorizontalAlignment="Stretch"
           Width="200" 
           Height="50"
           FontSize="36"
           Text="Hello world"
           TextAlignment="Center"
           Visibility="Collapsed" />

<Border Grid.Row="1" 
        Width="{Binding ActualWidth, ElementName=_sampleText}" 
        Height="{Binding ActualHeight, ElementName=_sampleText}">
  <Border.Background>
    <VisualBrush Stretch="None" 
                 Visual="{Binding ElementName=_sampleText}" />
  </Border.Background>
</Border>
</Grid>

I want my visual to be render even if the control he bind too is not visible. Is there a way of doing that?

You could also place the TextBlock in a Border and make that Hidden:

<Border Visibility="Hidden">
    <TextBlock ... />
</Border>
