hi,

check this code

in child window:
  ClientScript.RegisterStartupScript(this.GetType(), "msg", "alert(' Details Added Successfully!');window.close();window.opener.__doPostBack('ChildWindowPostBack', '');", true);
in parent window:

in the page load event
 this.ClientScript.GetPostBackEventReference(this, string.Empty);

        if (this.IsPostBack)
        {
            string eventTarget = (this.Request["__EVENTTARGET"] == null) ? string.Empty : this.Request["__EVENTTARGET"];

            if (eventTarget == "ChildWindowPostBack")
            {
//do your coding to fire listbox
            }
}
