How to get post back data in page pre-init stage? Can I do that?

---

Use the

Request[key] 

dictionary directly

EDIT: But, as Oded said, no ASP.NET "services". You get the raw post back data and have to do everything self.

EDIT2:

var val = Request["NAME_OF_MY_HTML_INPUT_ELEMENT"];

not testes, but should also work:

var val = Request[myHiddenFieldControl.UniqueID];

---

No, you can't.

Post back data is not available at that point as can be seen here.

If the request is a postback, the values of the controls have not yet been restored from view state.
