Why don't Response.Write("MasterPage_SaveStateComplete<br/>") launch?
<p>I add a Site.Master file to my ContentPage, I hope to see the order of page launch, 
but I find some codes such as  Response.Write("MasterPage_SaveStateComplete"), Response.Write("MasterPage_PreRenderComplete"); are not launched why? </p>
