I am using asp:TemplateField instead of asp:BoundField. I have coded a TextBox inside a DetailsView. I then coded a SqlDataSource asp:ControlParameter and the ControlParameter cannot find the TextBox. Is this another case of needing FindControl? Below is the pertinent code, minus the validators.

<asp:DetailsView ID="SchedulingDetailsView" runat="server"
    BorderWidth="0px"
    DataSourceID="SqlTrips"
    DataKeyNames="Id"
    OnItemInserted="SchedulingDetailsView_ItemInserted "
    AutoGenerateRows="false"
    AutoGenerateInsertButton="true"
    DefaultMode="Insert"
    CssClass="SchedulingDetailsView"
    CommandRowStyle-CssClass="SchedulingDetailsViewCommandStyle">
<Fields>
<asp:TemplateField>
    <HeaderTemplate>
       <asp:Label ID="lblDepartureDate" runat="server"
            CssClass="SchedulingDetailsViewHeader"
            Text="Departure Date:">
       </asp:Label>
    </HeaderTemplate>
    <InsertItemTemplate>
         <asp:TextBox ID="tbDepartureDate" runnat="server"
             CssClass="SchedulingDetailsViewItem">
         </asp:TextBox>
    </InsertItemTemplate>
 </asp:TemplateField>
</Fields>
</asp:DetailsView>

<asp:SqlDataSource ID="SqlTrips" runat="server"
  ConnectionString="<%$ ConnectionStrings:fireConnection %>"
  InsertCommand="INSERT INTO [fireTrips] ([DepartureDate],[ReturnDate],[DestinationCity],[DestinationCountry],[TripDescription],[Cost],[TripStatus],[Availability]) VALUES (@DepartureDate, @ReturnDate, @DestinationCity, @DestinationCountry, @TripDescription, @Cost, @TripStatus, @Availability)"
  InsertCommandType="Text">
 <InsertParameters>
  <asp:ControlParameter ControlID="tbDepartureDate" Name="DepartureDate" Type="DateTime" />

    </InsertParameters>
</asp:SqlDataSource>

How do I access the controls inside the DetailsView from the ControlParameter.

Thanks in advance for any help given.

The problem was solved by adding Text='<%# Bind("DepartureDate") %>'> to each of the fields. Changing DepartureDate to the appropriate column name.

I discovered this by creating an asp:BoundField and then converting it to a asp:TemplateField and examining what the converted asp:TemplateField looked like.

So the connection between a TemplateField contained control and the SqlDataSource is the Text parameter of the control.
