I must be totally missing something, but I'm confused about these statements in the book:

On postback, the story looks quite different. When you click the button to cause a postback, the following events are raised:
...
GridView1_RowCreated
GridView1_RowCreated
GridView1_RowCreated
GridView1_RowCreated
Page_Load
Button1_Click
Page_PreRenderComplete
— — — — — — — — -

It’s important to understand and remember that user-triggered control events like a Button control’s Click or a SelectedIndexChanged of a DropDownList occur after the Load event of the Page.

-----------------------------------------------
But me clicking the button obviously initiates the PostBack. So how is the event happening after the subsequent load of the page? The click is what cause the page to load, no? Very confused.

Yes, you clicking on the button happens first. However that happens on the server side. In order to respond to that click, the Click event fires on the server. But before that can happen, other stuff needs to happen first. The page doesn't have a button that can be clicked until it's loaded for example, so those events need to happen first.

Does that help?
