I am working on a Asp.net project, where i need to fill a form with two two fields. Let’s say

<form>
 a_text <asp:TextBox ID="UserName" runat="server"/>

        <asp:CheckBox ID="TestCheckboxes" runat="server" CssClass="tb_sm" />

        <asp:DropDownList ID="DropDownList1" runat="server"  
            CssClass="ddlb" Width="210px" Height="30px"  DataSourceID="SqlDataSource2" 
            DataTextField="OrderPeriod" DataValueField="OrderPeriodID">
        </asp:DropDownList>

       <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$  ConnectionStrings:ProdDB %>" SelectCommand=" # Some Command">
     </asp:SqlDataSource>

     <asp:Button ID="ButtonSubmit" runat="server" Text="Done" />

1 hello you hgave error on DataSourceID=”SqlDataSource2″

-> DataSourceID="SqlDataSource1"

You must select good SqlDataSource

try with this code

        <asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True" 
            CssClass="ddlb" Width="210px" Height="30px"  DataSourceID="SqlDataSource1" 
            DataTextField="OrderPeriod" DataValueField="OrderPeriodID">
        </asp:DropDownList>

        <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$  ConnectionStrings:ProdDB %>" SelectCommand=" # Some Command">
        </asp:SqlDataSource>

DropDownList1.Text
