title: In WPF, how to clear DataBinding in a DataGrid?
body: <p>I am using WPFToolKit DataGrid in my application. I have bound the DataGrid to a XMlDocument.
  The grid displays the Data from XML. I have to remove all the bindings in DataGrid and reset it during some event.</p>
  
  <p><strong>Now my question is how do I remove the DataBinding between DataGrid and XMLDocument.</strong><br>
  <br>
  I have tried something like this ::</p>
  
  <pre><code>dg.SetValue(DataGrid.BindingGroupProperty, null); //doesn't work
  </code></pre>
  
  <p>What am I doing wrong?</p>
