How to code a DropDownList on a bit data type in DetailsView?

[joker77]

Hi,

 

I'm having a bit of trouble with the DropDownList control, on a bit data type. I have one screen for inserting records, and another for updating. The insert works fine, but my update screen keeps crashing with the message "lstBluetooth has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value"

 

The code I have for the dropdown is:

               <asp:TemplateField HeaderText="Bluetooth">
                   <EditItemTemplate>
                       <asp:DropDownList ID="lstBluetooth" runat="server" Width="100px" 
                                         DataValueField="Bluetooth" SelectedValue='<%# Bind("Bluetooth") %>'>
                           <asp:ListItem Text="True" Value="true"/>
                           <asp:ListItem Text="False" Value="false"/>
                       </asp:DropDownList>
                   </EditItemTemplate>
                   <ItemTemplate>
                      <asp:Label ID="lblBluetooth" runat="server" Text='<%# Eval("Bluetooth") %>' />
                   </ItemTemplate>
               </asp:TemplateField>

I've tried changing the Value field for the 2 ListItems to 0 and 1 (as this is all that will ever be retrieved from the field Bluetooth which is defined as a bit in the database).

 

The above code for the DropDownList works fine on my insert page. The template field above exists in a DetailsView control, which used a PageDataSource for binding.

 

Any ideas on how to get this working?
