ok I seem to have 2 possible solutions.
The first is just let the server side events occur after
CreateChildControls(). The downside to this is that I will have to
enforce CreateChildControls() to run a second time which means doing
everything twice and will be slower but should at least work.
The other solution seems to be to handle all the events client side
and from there manually send a postback event back and set the
argument to a string that contains all of the event information I need
and parse that string (Me.Page.Request.Params("__EVENTARGUMENT")) at
the beginning of CreateChildControls or maybe Init() and so handle it
before i create any child controls.
Does the second solution sound workable? Anyone done anything like
this before?
