使用Jqgrid和Ajaxfileupload上传文件

I'm working with a jqgrid and I would like to upload a file (pictures and pdf's). I've seen a lot of examples but nothing... I'd like to do un ajaxfileupload. Here is my code,

 colModel: [
        { name: "id", index:"id", key: true,width: 30,editable: false },

        { name: "name", index:"name", width: 100,editable: true },           
        { name: "fileToUpload", 
          editoptions: {
              enctype: "multipart/form-data"
            }, 
            edittype:'file',
            index: 'fileToUpload', 
            width: 150,
            align: "left",
            editable: true },
    ],
