I have a transaction table with a field called product. There is a limited number of choices for product so I also have a product table. I am showing the transactions in a ListView with a dropdownlist for Product. The field Product can be blank (all works well then). The user can leave the field blank or they can choose from the dropdownlist. I am running into a problem with the dropdownlist in the Edit Template. No matter what the product is in the transaction file, I get a page error of "ddlEditProduct has a SelectedValue which is invalid because it does not exist in the list of items". I have verified the product does exist in the product table.
My markup is:
<asp:DropDownList ID="ddlEditProduct" runat="server"
SelectedValue='<%# Bind("Product") %>' >
using 3.5 and C#
