Row level functionality

Hello,

Is their a way where i can bind an Id with row in datatables?

I get 3 columns from my database and display 2 in datatable to user, but what i want is to attach 1th column (which is Id) to whole row so that when user clicks on a particular row, it takes user to different page depending on Id.

ex

"aoColumns": [
                        { "mData": "Id",
                            "bSearchable": false,
                            "bSortable": false,
                            //"bVisible": false,
                            "fnRender": function (oObj) {
                                return '<a href=\"Details/' + oObj.aData[0] + '\">Id</a>';
                            }
                         },

                        { "mData": "FullName" },
                        { "mData": "Age" }
                    ]

and this is what i get in Json

{"sEcho":"1","iTotalRecords":1,"iTotalDisplayRecords":1,"aaData":[{"Id":425,"FullName":"xxx","Age":21,}]}

also oObj.aData[0] always comes out as undefined? i am showing FullName and Age but want user to click on row level.

Any help will be appreciated

Thanks
