Page controls are actually classes, so the easiest way to do this probably is to implement properties on the control which can be set from the parent. THis is generally more appropriate than setting Session variables, which require a significant (comparitively) amount of overhead as there's always boxing involved as well as writing and retrieving from the Session store (especially if it's not an InProc session store such as the StateServer or SQL Server one of which should always be used with ASP.Net IMHO).

Note that page controls by default aren't added to the Form as properties like other controls, so you may have to manually perform this step after dropping the custom control on the Web form. Just add the property like the other page controls. After that you can reference it from teh main form with

this.MyPageControl.Property

>I'm designing a web form that has a user defined control (ascx) on it. This ascx needs values from parent container controls. How do I pass values to the child ascx? I need these values when the ascx's Save button is clicked. I don't know if session variables would be appropriate or not?
