I had been messing around with the paths but couldn't seem to get it to work. However, when you open JQuery.JQGrid.js, you see that one of the first lines is
var pathtojsfiles = "js/"; // need to be adjusted When I changed "js/" to point to all of the other Javascript files associated with JQGrid, it worked just fine. So, I changed it from "js/" to "../JavaScript/JQGrid/js/". Thanks.
