I think you should post your data without stringifying your JSON:

$("#UpdateTbl").click(function () {
    var id = $(this).attr("edit-id");
    var user = {};
    debugger;
    user.DayDesc = $("#DaybookDesc1").val();
    user.VoucherNo = $("#Prifix1").val();
    user.VoucherNo1 = $("#Surffix1").val();


    $.ajax({
        type: "Post",
        contentType: "application/json; charset=utf-8",
        url: "DaybookMast.aspx/UpdateData",
        data: {"objEmployee": user, "eid": id},
        dataType: "json",
        success: function (data) {
            if (confirm("Are you want to change !") == true) {
                alert("Updated successfully");
            } else {
                alert("canceled changes");
            }
        },
        error: function (data) {
            alert("Error while Updating data of :" + id);
        }
    });
});

On a side note: don't do SQL injection in your DB statements... Use parameters instead to avoid possible security breaches. More info @ https://stackoverflow.com/a/6548006/2805121
