        var rowname = grid.rows[rowIndex].cells[1].textContent;
        var rowcontact = grid.rows[rowIndex].cells[2].innerHTML;
        var rowaddress = grid.rows[rowIndex].cells[3].innerHTML;

                };

But when i run that page it becomes disable and immediately enable automatically.....:( Can anyone give me solution ???

You have to call this function after form is completely loaded. Use below code to make it that happen if you are using jQuery.

$( document ).ready(function() {
    DoStuff(lnk);
});
