Javascript:

$(function () {
$("tr[name='StudentTableRow']").click(showStudent);    
});

function showStudent() {    
var link = '/Base/ShowSpecificStudent';
var id = this.cells[0].innerText;

$.ajax({
    type: 'POST',
    url: link,
    data: { id: id },
    dataType: 'json',
    success: function (result) {

        //$("#StudentDetail").html(result);
    },
    error: function (result) {
