RaisePostBackEvent question

[Karl Hungus]

how come RaisePostBackEvent doesn't work correctly if the
IPostBackDataHandler isnt implemented. It seems that I must at least have:

public bool LoadPostData(String postDataKey, NameValueCollection values) {
return false;
}

public void RaisePostDataChangedEvent() {
}
In order for the eventArgument string to come through properly in:

public void RaisePostBackEvent(String eventArgument) {
Anyone know why?

TIA
Karl

If you have IPostBackDataHandler implemented and you wish
IPostBackEventHandler.RaisePostBackEvent called (means you have implemented
both interfaces), you'd need to use Page.RegisterRequiresRaiseEvent to get
RaisePostBackEvent called . Otherwise it is not called at postback
processing stage.

If this doesn't help, what kind of control it is in question? If it is a
composite one, you'd need to implement INamingContainer interface for
postback data to be routed correctly. Post some more code.

Im asking why it doesnt work if you *dont* implement IPostBackDataHandler. I
dont need to do anything with either method of that interface.

If I do not implement that interface, my RaisePostBackEvent is called but
the eventArgument is empty. If I do implement it, just in a barebones way,
as described below, eventArgument behaves correctly.
