Marconcilio, you need to cancel the default click behavior, either with a return false or a event.preventDefault , in this way the postback will not be executed.

Then in the Sim of dialog you can do the postBack manually. For this you can use the __doPostBack method.

var PassoWorkflow = parseInt(<% =vsIdPassoWorkflow %>);
var lnkGravar = "<%= this.lnkGravar.ClientID %>";
function CheckConfirm(IdPassoWorkflow) {
    if (IdPassoWorkflow == 2) {
        var dialog = jQuery("#EncaminharGestor").dialog({
            resizable: false,
            height:140,
            modal: true,
            buttons: {
                "Sim": function() {
                    $( this ).dialog( "close" );
                    __doPostBack(lnkGravar, '');
                },
                Cancel: function() {
                    $( this ).dialog( "close" );
                }
            }
        });

        dialog.dialog("open");
        return false;
    }
}
