'StateList' has a SelectedValue which is invalid because it doesnot exist in the list of items.

    I'm getting this error when my page loads. The control is not a dependent control. Below is the
    code used to populate the control.

    IDataReader dr = DB.GetData("select Name, Abbrv from State");
    StateList.DataSource = dr;
    StateList.DataTextField = "Name";
    StateList.DataValueField = "Abbrv";
    error here ---> StateList.DataBind();

    Here's the control declaration

    <asp:DropDownList ID="StateList" runat="server"></asp:DropDownList>

    This used to work and the only thing that changed is that an application in a subdirectory of the
    website was changed so that it's not a separate application anymore. This is now happening on all
    databound dropdownlist controls in the website.

    I found many references to this problem but the scenarios all involve dependent controls or null
    values in the data, neither of which is a problem in my case. I'm stumped.
