This is a jquery plugin that does the transformation client side. You haven't tagged your question to indicate what server side technology you are using, but from your description I infer it is ASP.NET.

Here's a sample page I've setup illustrating how to achieve the functionality you are looking for:

<%@ Page Language="C#" %>
<%@ Import Namespace="System.Linq" %>

<script type="text/C#" runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            listBox.DataSource = new[] { "Aries", "Taurus", "Gemini" };
            listBox.DataBind();
        }
    }

    protected void BtnClick(object sender, EventArgs e)
    {
        var selectedItems = (from item in listBox.Items.Cast<ListItem>()
                 where item.Selected
                 select item.Text).ToArray();
        result.Text = "You selected: ";
        result.Text += string.Join(",", selectedItems);
    }
</script>
