Well, i asked that a short while back as well, you'll have to use a html button and in the onclick bit put: window.open("website url","one_word_id_type_thing","resizable=0,width=550,height=400") resizable=0 means you cant resize it 1 means that you can. Just thought, to open a page in a new window, and keep the web forms button, add: using System.Diagnostics; then in the button put: Process.Start("website url"); that should open it in a new window.
