Hello
I tried your sample and it works for me (Ext.Net 2.4.0.30091)

Hovewer I would recommend to modify the code of Page_Load

protected void Page_Load(object sender, EventArgs e)
	{
		if (IsPostBack == false)
		{ 
// what you have now
                }
        }

if you still have problems, , can you take firebug or fiddler and check that part if request is something like (third line is important)


__EVENTARGUMENT btnGuardar|event|Click
__EVENTTARGET ResourceManager1
rsmAlimentos [{"RecordID":3,"RowIndex":2}
