How can I use 2 sqldatasources to populate a dropdownlist? This is the relevant code I have but it's not working. Thanks.

<asp:DropDownList ID="DropDownList1" runat="server" DataSourceID="SqlDataSource1"
                DataTextField="Name" DataValueField="Name">
            </asp:DropDownList>
 <asp:DropDownList ID="DropDownList2" runat="server" DataSourceID="SqlDataSource2"
                DataTextField="Name" DataValueField="Name" Visible="true">
            </asp:DropDownList>


            <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:BRConnectionString %>"
                SelectCommand="select Name from Company"></asp:SqlDataSource>
            <asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:BRNewConnectionString %>"
                SelectCommand="select Name from Company"></asp:SqlDataSource>


    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {

            foreach (var item in this.DropDownList2.Items)
            {
                this.DropDownList1.Items.Add(item.ToString());
            }

        }
    }
