Hey thanks for the reply.

Here is the code for the ddl:
                                                    <asp:DropDownList Width="224px" ID="ddlFACID" runat="server">

I searched the codebehind for anything that references the ddl and there isn't anything other than the code that I'm having problems with, which is...

Dim dvFac1 As DataView = dsLookupTables.Tables("Facilities").DefaultView
ddlFACID.DataSource = dvFac1
ddlFACID.DataValueField = "FacID"
ddlFACID.DataTextField = "FacilityName"

The error that I get is "'ddlFACID' has a SelectedValue which is invalid because it does not exist in the list of items." When I debug I learn that the ddl for some reason already has a selectedValue of "57" (quotes included). Of course that is not in the dataView so it throws an error. The really weird thing is that I haven't even yet assigned a value to ddlFACID.SelectedValue. Ordinarily, I would do that right after binding to a data source.
