DropDownLists Edit In Grid View To Display Names But Have Value Of User_ID ... Possible?

Hello,
I have inserted a drop down list in my Edit template of Grid view.  This DDL should control the User_ID who is responsible for the Computer being edited.  However I want it to display the User Names rather than the user IDs.  I have a COMPUTERS and a USERS table.  They are related by having User_ID in both. 
 
Below is my grid view with the parts i feel relative highlighted in bold:

<asp:GridView ID="GridView1" runat="server" AllowSorting="True"
        AutoGenerateColumns="False" DataKeyNames="Computer_ID"
        DataSourceID="SqlDataSource1" CellPadding="4" ForeColor="#333333"
           GridLines="None">
           <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
           <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
        <Columns>
            <asp:CommandField ShowEditButton="True"/>
            <asp:BoundField DataField="Computer_ID" HeaderText="Computer_ID"
                InsertVisible="False" SortExpression="Computer_ID" ReadOnly="true" />
            <asp:BoundField DataField="Computer_Name" HeaderText="Computer Name"
                SortExpression="Computer_Name"/>
            <asp:BoundField DataField="Manufacturer" HeaderText="Manufacturer"
                SortExpression="Manufacturer"/>
            <asp:TemplateField HeaderText="User Name" SortExpression="Name">

                <ItemTemplate>

        SelectCommand="SELECT COMPUTERS.Computer_ID, USERS.User_ID, COMPUTERS.Computer_Name, COMPUTERS.Manufacturer, USERS.Name FROM COMPUTERS INNER JOIN USERS ON COMPUTERS.User_ID = USERS.User_ID"
        UpdateCommandType="StoredProcedure" UpdateCommand="StoredProcedure1" 
        >
        <UpdateParameters>
            <asp:Parameter Name="Computer_ID" Type="Int32" />
             <asp:Parameter Name="User_ID" Type="Int32"/>
             <asp:Parameter Name="Name" Type="String" />
