why does the ASP dropdownlist not work when binding?

I have placed a dropdown list in the edititemtemplate 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:DropDownList ID="DropDownList2" runat="server" AutoPostBack="True"
DataSourceID="SqlDataSource2" DataTextField="Type"
selectedvalue='<%# Bind("ServiceProviderType") %>'>
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.

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.

Thanks - please bear with the newbie.

Is there a "ServiceProviderType" in your data source?
