Jquery css border radius specific corners radius?

Hello I am trying to change the border-radius of specific corners of some uls with jquery sortable on the method sort.

Here is my code so far and it is not working, any ideas?

sort: function() {
    var borderSet = $('#fluidWrap ul:last-child').attr('id');
    if (borderSet == 'sideWrap') {

        $('#sideWrap ul').css({BorderTopRightRadius: 10, BorderBottomRightRadius: 10});
    }
    else {
        $('#sideWrap ul').css({BorderTopLeftRadius: 10, BorderBottomLeftRadius: 10});
    }
}

try

.css({'border-top-right-radius': 10})

You could use:

border-radius: 0px 10px 0px 0px;

which is:

border-radius: [top-left],[top-right],[bottom-right],[bottom-left];

This tool is very good for css3: css3generator.com

It may be more helpful to try using the jQuery corner plugin as it will also account for browser differences in border radius definitions.

this should work

css({BorderTopRightRadius: '10px', BorderBottomRightRadius: '10px'})
