    why does the ASP dropdownlist not work when binding?

    I have placed a dropdown list in the edititemtemplat e of a formview control and followed specific MSDN instructions on how to bind the list source to a separate SQL lookup data source but have the formview bound to the main data source. If I set the selecteditem value to bind to the formview control I always get the following error:
    'DropDownList2' has a SelectedValue which is invalid because it does not exist in the list of items.

    This is my asp:
    <asp:DropDownLi st ID="DropDownLis t2" runat="server" AutoPostBack="T rue"
    DataSourceID="S qlDataSource2" DataTextField=" Type"
    DataValueField= "Type"
    selectedvalue=' <%# Bind("ServicePr oviderType") %>'>
    </asp:DropDownLis t>
    I have read over 50 posts on this and got nowhere - HELP!

    Hello garyhumf7,

    From my understanding this is a "Classic" ASP forum. Your question should be posted in the ".NET" section.

    Sorry,

      You are correct, this definitely is a "ASP.NET" question, and doesn't belong in the "classic ASP" forum.

      I have moved it over for you.

          Is there a "ServiceProvide rType" in your data source?
