title: How to run telerik RadWindow from code behind
body: <p>I am trying to run telerik rad window from code behind. But I have some issues.
  I don't know is it important but I am trying to run rad window from button clicked in edit mode from rad grid.</p>
  
  <pre><code>RadWindow window1 = new RadWindow();
  window1.NavigateUrl = "http://www.google.com";
  window1.VisibleOnPageLoad = true;
  window1.ID = "RadWindow1";
  window1.Width = 500;
  window1.Height = 300;
  window1.VisibleOnPageLoad = true;    
  rwm_WindowManager.Windows.Add(window1);
  </code></pre>
  
  <p>On the page I also have <code>RadAjaxManager</code> and <code>rwm_WindowManager</code> I put in <code>RadAjaxPanel</code>.<br/>
  Problem is that this rad window never shows up. There are no errors but no rad window also.</p>
