ASP.NET Partial Back Part Size Problem

In my page_load I create

HiddenField newField= new HiddenField();

and then assign it to him newField.ID = "someid"and Value="0". on a partial postback (called by UpdatePanel), I check

Request.Form["someid"]

in the panel_Load event during postback. but the request returns null since someid was not sent back. (not contained in the Request.Form collection) Why can this be?

thank

ASP.NET manages the identifier when rendered by the default client. To access it from the Form collection, try the following:

Request.Form[newField.ClientID]
