title: Where should I populate a control based on a selected value from master page
body: <p>I have the following situation:</p>
  
  <ul>
  <li>Master page contains a tree control</li>
  <li>Page use the previous master page</li>
  <li>Control populates its items based on the selected node in the tree (which is in the master page)</li>
  </ul>
  
  <p>The question is:
  Where should I populate a control based on a selected value from master page?</p>
  
  <p>The problem is that the <code>Load</code> event of the master page is fired after the <code>Load</code> event of the page, so I couldn't handle the selected node from the master page in the <code>Load</code> event of the page.</p>
  
  <p>I tried also to use the <code>PreRender</code> event of the page, but the control is not populated true.</p>
  
  <p>Any help!</p>
