Multiple values in db generated dropdownlist

I have a stored procedure which returns data to a dropdownlist in asp.net VB the back end looks like this:

Dim aDataAdapter As Data.SqlClient.SqlDataAdapter
        Dim aDataset As New Data.DataSet("MyDataSet")

        aDataAdapter = New Data.SqlClient.SqlDataAdapter("dbo.[listing]", strConn)
        aDataAdapter.SelectCommand.CommandType = Data.CommandType.StoredProcedure
        aDataAdapter.Fill(aDataset, "Groups")

        Dim Table As Data.DataTable = aDataset.Tables("Groups")

        DropDownList1.DataSource = Table
        DropDownList1.DataBind()

And the front end looks like this:
<asp:DropDownList ID="DropDownList1" runat="server" CssClass="textstyle" AppendDataBoundItems="True" DataTextField="name" DataValueField="id">
<asp:ListItem Value="--">--Please Select--</asp:ListItem>
</asp:DropDownList>

This works fine but how can i get not only the name in the dropdown list but also other data as well, not in the value field but in the text part that the user sees: example:

Name | Country ID

Thanks in advance
