Ok,
I have modified the code for the webservice in charge of saving the edited data and now i can add rows, edit rows and delete rows when using the pager and editurl property as posted in my previous post.
At least, everything works with the form editing predefined with the pager.
Now, I'll try again to use cell editing.
Here is my current code for the saving data webservice:
using System;
using System.Collections.Generic;
using System.Collections.Specialized;
using System.ComponentModel;
using System.Web;
using System.Web.Services;
using System.Web.Script.Services;
using System.Web.Script.Serialization;
using MySql.Data.MySqlClient;
namespace Test
