Hi Oliver,
After some tests on my local side, seems the Event sequence are always as
we normally expected:
Contro's creation events ----> Page_Load/Control's Load events ---->
PostBack events
Also, below is my simple test page, which output
=============
dgEvent_ItemCreated get called!
dgEvent_ItemCreated get called!
dgEvent_ItemCreated get called!
Page_Load get called!
=============
you can also have a test on your side to see whether you still get the
strange event sequence.
