$('[id$=txtname]').rules("add", {
             required: true,
             messages: {
                 required: "fill this"
             }
});
//for the textbox you want to compare with 
$('[id$=txtname2]').rules("add", {
             equalTo: '#txtname',
             messages: {
                 required: "values not does not match."
             }
});
