title: Popup temporary form in the current one
body: <p>I have one main form and another which I have to popup in the following code:</p>
  <pre><code>private void barButtonItemEditCopy_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e)
      {
          PopupForm pop = new PopupForm();
          pop.Show();
      }
  </code></pre>
  <p>and I want when event itemclick happens to lock current form afret <code>pop.Show()</code> and after closing pop form to continue with the main one. Now when I hit itemclick event the whole function pass and after that I see the popupform and my main form from which I popup is still available.</p>
