title: ModalPopupExtender Animations OnShown
body: <p>I am learning ASP .NET and came across modal popup extender. I found that animations are possible with modal popup but I have a question as to what is the difference between OnShowing and OnShown tags. A google search gave me </p>
  
  <pre><code>OnShowing – Called before the modal popup is shown.
  OnShown – Called after the modal popup is shown.
  OnHiding – Called before the modal popup is hidden.
  OnHidden – Called after the modal popup is hidden.
  </code></pre>
  
  <p>But, I am confused about something. When I click on the target button and use OnShowing, there is no animation effect. But when I use OnShown, the animation is successful. Now, isn't the OnShowing called BEFORE the modal popup is shown, so when I Click on the target button, it is the function OnShowing which is supposed to be called. I think I am missing something here. Thanks for the help!</p>
