I have a pretty simple page with a GridView, a DropDownList as a filter to
the GridView, and a filter Button.  Both gridview and dropdownlist are bound
to SqlDataSources.  I am setting another parameter in the Selecting event of
the datasource, but the strange thing is the order of the events that fire.

When I first enter the page the event order is:

Page_Init
Page_Load
SqlDataSource.Selecting

But when I press the filter button and get a postback, the event order
changes to:

Page_Init
SqlDataSource.Selecting
Page_Load

Why would this happen?  There are things that have to happen in the
Page_Load before the Selecting event happens.  Its very disturbing that I
can't count on the life cycle of the page to be consistant...
