I got your sample to work the way you want it with the following changes:
  1) Changed the GridView to have a SaveAll button on the header and converted the "Qty Labels" column to be edit always.  Like this:
         
                <!%--Read Only Fields here--%>
               
                   
                       
                   
               
               
                   
               
             
  2) Changed the BindFunction to reload the data W/O binding like this:
   void BindGrid(Boolean LoadDataOnly)
        {
            DataSet oDs = new DataSet();
            oDs.ReadXml(this.XmlFile);
            GridView1.DataSource = oDs;
            if (!LoadDataOnly)
                GridView1.DataBind();  //Only bind AFTER data is changed
        }      
  3)  Added the HandleSaveAll command:

        protected void HandleSaveAll(object sender, GridViewCommandEventArgs e)
        {
            if (e.CommandName == "SaveAll")
            {
                BindGrid(true);
                DataSet oDs = (DataSet)GridView1.DataSource;
                foreach (GridViewRow row in this.GridView1.Rows)
                    if (row.RowType == DataControlRowType.DataRow)
                        UpdateRow(oDs, row.RowIndex, row.DataItemIndex);
 
                oDs.AcceptChanges();
                oDs.WriteXml(this.XmlFile);
                BindGrid(false);
            }
        }
        protected void UpdateRow(DataSet oDs, int rowIndex, int DataRowIndex)
        {
            //Scrape the values of controls in edit mode
            //string strStyle = ((TextBox)GridView1.Rows[rowIndex].Cells[2].Controls[1]).Text;
            //string strName = ((TextBox)GridView1.Rows[rowIndex].Cells[3].Controls[1]).Text;
            string strAntal = ((TextBox)GridView1.Rows[rowIndex].Cells[4].Controls[1]).Text;
 
 
 
            //Update the data
            oDs.Tables[0].Rows[DataRowIndex]["Antal"] = strAntal;
        }
