title: Catch activated user control c#
body: <p>I am working with <code>C#</code>. I was wondering how to catch an event when a user control is activated?</p>
  
  <p>I have created a document manager with <code>DevExpress</code> using <code>windowUIview</code>.</p>
  
  <p>On the start page, I have <code>tiles</code>.</p>
  
  <p>When I click <code>tiles_1</code>, it loads <code>userform_1</code>, I want to go back to start page and click <code>tile_1</code>, and start <code>userform_1</code> again. But I dont know how to do that.</p>
