Sounds like you will need both server-side and client-side code. Server-side, take a list of all skills and a list of employee skills and create a new list using LINQs “Except”, something like:

var unusedSkills = db.skils.ToList().Except(db.empSkils);
@viewbag.empskil = new selectlist(unusedSkills,"skillid","skillname");

Client-side, you’ll want to use jQuery to remove a skill from the list after it is selected and add it to the employee’s list, something like:

$("#button1").click(function(){
    $("#list1 > option:selected").each(function(){
        $(this).remove().appendTo("#list2");
    });
});
