Prerender()

Marco

Hello,
I read this
http://www.c-sharpcorner.com/UploadFile/Santhi.M/ASP.NETLifeCycle11282005043446AM/ASP.NETLifeCycle.aspx
and I was wondering if there's anyone that can explain to me what Prerender should do, for example for a button or a calendar component.
I can't imagine it; can you show me few lines?
thanks

thanks but I don't still understand what it can update or change. Can you give me some examples, please? Is it something put inside the head tag or what? Either it doesn't produce code to put in the html page but it only change the state of some variabiles? Can you give me an example on the Calendar component? What does it can do for it? thanks

It is the event before the page is actually displayed on the screen. Or more technical, it happens BEFORE the render method gets called which creates the HTML code using the HtmlWriter. What's intersting is, that the viewstate isn' t updated and stored yet. Viewstate is the state of the webpage. If you need to change/update something which has to go into the viewstate, you should do this in the prerender event handler. If you do this after the render event, it will not be written to the viewstate, since the viewstate gets written just after the render event occurred.
