title: server side click event doesn't fire on LinkButton when PostBackUrl property has been set to another page
body: <p>I put a linkbutton control named as "Logout" on my webpage with VS 2010.
  When users press the "Logout" linkbutton , I want the system to do two things.
  First is to trigger a server side click event to do some things such clear all session variables etc..
  Second is to redirect to user to another page such logon.aspx </p>
  
  <p>So I wrote following codes</p>
  
  <pre><code>protected void Page_Load(object sender, EventArgs e)
  {
      if (!this.IsPostBack)
      {
          LinkButton1.PostBackUrl = "LogOn.aspx";
      }
  }
  
  protected void LinkButton1_Click(object sender, EventArgs e)
  {
      Session.Abandon(); 
      ....
      ....
  
  }
  </code></pre>
  
  <p>But when the programs runs , any user clicks the linkbutton.The codes of LinkButton1_Click never be executed, because the page has already been redirect to Logon.aspx page and never do the LinkButton1_Click()</p>
  
  <p>My Question is why LinkButton1 offers PostBackUrl property and server-side click event , but it seems that they don't cooperate very well ~</p>
