Hi
each time you populate a DDL ( or every other control )
it's previous ViewState is Cleared/Ignored
that may be the cause for that
the SelectedIndexChange isn't fired
becuse according to the Page the contence has
change , thus irrelevant ( even if it's contence is the same )
-------------------------------------------
If my answer helped you please press "Yes" bellow

The bizarre thing is the AutoPostBack="True" does fire. If I place a
breakpoint in my code on the Page_Load it is hit after I select
something in the DropDownList. But when it hitsthe line to see if
it's a postback or not it says it isn't. If I hover over if(!
this.IsPostBack) it tells me IsPostBack is false.

So even the the postback has fired and the breakpoint has been
triggered in my Page_load method, it thinks it's not a postback.
That's what baffles me...
