I think you are missing some things in your DDL,

<asp:DropDownList
          id="drpTime"
          runat="server"
          DataTextField="Time"
          DataValueField="TimeID"
          [b]DataSourceID="ObjectDataSource3"[/b]>
      </asp:DropDownList>

and to post code its the [ not the < !

let us know

 

[NickMalloy]

There is no datasource for the DDL because it doesn't populate from a database. It is all on the page.

 

[adamroof]

Yeah, but i think you have to associate with the datasource to apply the update parameters. Have u tried, does it get error, simplify it a bit?

<asp:DropDownList ID="drpTime" runat="server" SelectedValue='<%#Bind("startTimeDisplay") %>'
[b]DataSourceID="ObjectDataSource3"[/b]>
                                    <asp:ListItem Text="1" Value="1:00"></asp:ListItem>
                                    <asp:ListItem Text="2" Value="2:00"></asp:ListItem>
                                    <asp:ListItem Text="3" Value="3:00"></asp:ListItem>
                                    <asp:ListItem Text="4" Value="4:00"></asp:ListItem>
                                    <asp:ListItem Text="5" Value="5:00"></asp:ListItem>
                                    <asp:ListItem Text="6" Value="6:00"></asp:ListItem>
                                    <asp:ListItem Text="7" Value="7:00"></asp:ListItem>
                                    <asp:ListItem Text="8" Value="8:00"></asp:ListItem>
                                    <asp:ListItem Text="9" Value="9:00"></asp:ListItem>
                                    <asp:ListItem Text="10" Value="10:00"></asp:ListItem>
                                    <asp:ListItem Text="11" Value="11:00"></asp:ListItem>
                                    <asp:ListItem Text="12" Value="12:00"></asp:ListItem>
                                </asp:DropDownList>

as in this example...

<asp:DropDownList ID="ddlPriority" runat="server"
SelectedValue='<%# Bind("priority") %>' DataSourceID="sqlDS">
<asp:ListItem Value="0">low</asp:ListItem>
<asp:ListItem Value="1">middle</asp:ListItem>
<asp:ListItem Value="2">high</asp:ListItem>
</asp:DropDownList>

I get this error

'drpTime' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value

When I remove tthe selectedValue tag. The dropdown contains nothing related to my data. when I put the datavalue column, the only thing in the dropdown is the current time. and I still get the error on update.
