title: Unable to reset ProgressBar
body: <p>I am experimenting a behavior which makes me crazy.</p>
  
  <p>I have a <code>ProgressBar</code> which represents the evolution of an import in database (in percents, from <code>0</code> to <code>100</code>). </p>
  
  <p>After the import is done (<code>ProgressBar.Value = 100.0</code>), I open a log window with a code which looks like this :</p>
  
  <pre><code>RadWindow window = new RadWindow()
  {
      //Set some properties
  };
  window.Closed += Log_Closed;
  window.ShowDialog();
  </code></pre>
  
  <p>After the <code>RadWindow</code> is closed, I want to reset the <code>ProgressBar</code>. As you can see I use the function <code>Log_Closed</code> whose code is bellow :</p>
  
  <pre><code>private void Log_Closed(object sender, EventArgs e)
  {
      //pbImport.Value = pbImport.Minimum; (didn't work)
      pbImport.Value = 0;
  }
  </code></pre>
  
  <p><em>Note</em> : <code>pbImport</code> is my progress bar.</p>
  
  <p><strong>The instruction in</strong> <code>Log_Closed</code> <strong>has no effect.</strong></p>

  <p>Obviously, the progress bar is not updated in UI. I can't understand this. Thank you for your help.</p>
