I have a page with 2 Content Controls. Content1 has a SqlDataSource with a Control Parameter
that uses a Dropdown list. The dropdownlist is in Content2. I used viewsource to get
the dropdownlist control name which was
ctl00_ContentPlaceHolder6_ddlPersonFilter. I also got an error if I used ddlPersonFilter.
Thanks for any assistance.
Could not find control 'ctl00_ContentPlaceHolder6_ddlPersonFilter' in ControlParameter ''.

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" DataSourceID="dsProduct"DataTextField="Product" DataValueField="Product"AppendDataBoundItems="true"SelectedValue='<%# Bind("Product") %>' ><asp:ListItem Selected="True"></asp:ListItem></asp:DropDownList>

It is a general ASP.NET questions. Many times some items in dropdownlist will become inactive (retired)or active again. It is easy to handle in the new records which use only currently active items. But how to handle the inactive items which need to be used to show history records. It bothered me a long time, not sure how to solve this problem efficiently.
