I have a project in VS 2008 that is using Master Pages.  I want to add an event handler to the Page_PreRender event, but I don't see it listed under any of the control properties.  If I select a panel control, it has a Panel_PreRender event, but there is no "Page" control to select.  The top item in the list is DOCUMENT, which does not have any events.  Thanks!

Visual studio doesn't list the events for pages. I dont remember Visual Studio 2005 doing it either. And if you are looking for them under a control, you won't find them there. Controls expose their events, they have never exposed the Page events.

But here is what you do. You have two options.
1. In your <%@ Page directive on your markup page, add AutoEventWireup="true". Then in your code behind you type in your page eventhanders using the name "Page" followed by "_<eventname>" just like you did above with Page_PreRender. So you can also have protected void Page_Load(object sender, EventArgs e), protected void Page_Init(object sender, EventArgs e), etc. The runtime will register the eventhandler with the event for you as long as you follow the naming convention.

2. You wire them up yourself and you can use any name you want, but by convention you should still use the naming pattern. So in the constructor for your page, you can enter:
Page.Load += Page_Load, Page.PreRender += SomeOtherEventHandlerIfYouWant. In this case, set AutoEventWireup="false" otherwise you will will register it twice and it will fire twice.

There are other ways but they get more obscure.
