title: Suspend Databinding of Controls
body: <p>I have a series of controls that are databound to values that change every second or so.  From time to time, I need to "pause" the controls, so that they do not update their databindings (in either direction).  I then later need to "unpause" the controls, so that they can update the datasource with their values, and receive future updates from the source as normal.  How do I accomplish this?</p>
  
  <p><strong>Sample Binding:</strong></p>
  
  <pre><code>&lt;TextBox Text="{Binding UpdateSourceTrigger=LostFocus, Mode=TwoWay, Path=myData}"&gt;
  </code></pre>
