title: .net Page events firing order changing
body: <p>Ok this is a really annoying bug that I have been having issues with all morning!.</p>
  
  <p>I have a custom control that we have used on many project that has properties that are set and stored in Viewstate by the calling pages onload.  the control sets up childcontrols with propertes on the CreateChildControls() method of the custom control.</p>
  
  <p>Normally as usual on a postback the Page_Load event is fired then the CreateChildControls method of the control on the page is fired.  </p>
  
  <p>The strange thin though is we have a login system (custom membership provider) on the site and when a user is logged in the opposite happens first the CreateChildControls() method fires then the Page_Load so the control properties are wrong (set from the previous postback)</p>
  
  <p>How could the events be firing in a different order?  I thought all page events happened in the same order no matter what and I don't see how being logged in would change that order.</p>
  
  <p><strong>UPDATE:</strong> It seems the issue is I'm not calling EnsureChildControls() but I'm not sure where it should be called?  If several properies are set on the control which are used in setting up the child controls when should I call EnsureChildControls(), I guess I don't fully understand what EnsureChildControls() does?</p>
