Hi,

Unclear. js is not typed so int id=0; should be rather var id=0;

Also int result=data.d wouldn't likely make sense anyway. The result is not an integer but more likely a list of object which is likeky why your code doesn't work.

What if using var result=data.d;

Also the append line seems incorrect - no closing ), missing tags??? or is this a problem when copy/pasting your actual code?

Also you could first try append("<tr><td>A</td><td>B</td><td>C</td></tr>"); for example to validate the principle and then add the actual properties one at a time so that you can better see what fails exactly.

also you could cleanup the append:

    var id=0, opAction='';
    $(function () {
        BindGridview();
    });
    function BindGridview() {
        $.ajax({
            type: "POST",
            contentType: "application/json; charset=utf-8",
            url: "jQueryGridviewEmpEntry.aspx/BindGridview",
            data: "{}",
            dataType: "json",
            success: function (data) {
                int result = data.d;
                for (var i = 0; i < result.length; i++) {
                    $("<tr/>")
                         .append($("<td/>").text(result[i].id))
                         .append($("<td/>").text(result[i].Fname))
                         .append($("<td/>").text(result[i].MName))
                         .append($("<td/>").text(result[i]. LastName))
                         .appendTo("#NameDetails");
                }          
           }
       });
    }

Hi desikankannan,

 int id=0; opAction='';

We declare a JavaScript variable with the var keyword. Int is not a keyword, we could not use it to declare a variable in JavaScript code. Besides, if you’d like to parse a string and return an integer, you could use parseInt() function.
