title: Silverlight TextBlock Visibility property inital value before binding is applied
body: <p>I Have a TextBlock on Silverlight Page.</p>
  
  <p>XAML</p>
  
  <pre><code> &lt;TextBlock Text="*"  x:Name="HasChangesTextBlock" Foreground="Red" FontSize="14" Visibility="{Binding Path=HasChanges, Converter={StaticResource BooleanToVisibilityConverter}}"
                             Margin="5,0,0,0"&gt;
  
   &lt;/TextBlock&gt;
  </code></pre>
  
  <p>Page loading takes few moments. And before binding is applied I want  TextBlock to be collapsed, but default value of Visibility Property is Visible.</p>
  
  <p>Is there way to make TextBlock to be collapsed before binding is applied?</p>
