title: WPF - Is it possible to negate the result of a data binding expression?
body: <p>I know this works fine:</p>
  
  <pre><code>&lt;TextBox IsEnabled="{Binding ElementName=myRadioButton, Path=IsChecked}" /&gt;
  </code></pre>
  
  <p>...but what I really want to do is negate the result of the binding expression similar to below (psuedocode). Is this possible?</p>
  
  <pre><code>&lt;TextBox IsEnabled="!{Binding ElementName=myRadioButton, Path=IsChecked}" /&gt;
  </code></pre>
