Help C# ASPX Database/dropdown error

[Davidtheo]

I have a drop Download list that is being filled from a database:

My ASPX.cs file

[Select]

        myDataAdapter.Fill(myDataSet, "country,country_id");

        DropDownList1.DataSource = myDataSet;
        DropDownList1.DataValueField = "country_id";
        DropDownList1.DataTextField = "country";
        DropDownList1.DataBind();

my APSX File

[Select]

<asp:ScriptManager ID="ScriptManager1" runat="server">
                                </asp:ScriptManager>
                                <asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">
                                    </asp:DropDownList><br /><br />
                                <asp:UpdatePanel ID="UpdatePanel1" runat="server">
                                    <ContentTemplate>
                                       
                                        Adderss: label stuff
                                        Adderss: label stuff
                                    </ContentTemplate>
                                    <Triggers>
                                        trigger stuff
                                    </Triggers>
                                </asp:UpdatePanel>
