POpage_load event in Master and Content Pages

Body
copied!<p>Here is the sequence in which events occur when a master page is merged with a content page:</p> <p><a href="http://msdn.microsoft.com/en-us/library/dct97kc3.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/dct97kc3.aspx</a></p> <p>So, my problem is:</p> <p>I have one login page (not use master page), one master page, and hundreds of content page.</p> <p>I check login session <code>Session["loggedInUser"]</code> in master page (if not logged in, redirect to login page)</p> <p>So, when I don't log in, if I type the address of one content page, it must check login session in master page and redirect to login page, right? But it has two cases here:</p> <p>If in content page, I don't use anything related to <code>Session["loggedInUser"]</code>, it will redirect to login page, so, it's OK here!</p> <p>The second case: if I use <code>Session["loggedInUser"]</code> to display Username in content page for example:</p> <pre><code>UserInfo loggedInUser = (UserInfo)Session["loggedInUser"]; </code></pre> <p>it will return null object here, <strong>because the <code>page_load</code> in content page is fired before <code>page_load</code> in master page</strong>, so it thows null object instead of redirecting to login page.</p> <p>I also tried <code>Page_PreInit</code> in master page but no help</p> <pre><code>protected void Page_PreInit(object sender, EventArgs e) { if (Session["loggedInUser"] == null) { Response.Redirect("~/Login.aspx"); } } </code></pre> <p>Any suggestion?</p>
