How to make drop down menu enable with only one value
<p>I have a drop down menu that retrieved ID from database and four labels. From the user id, the labels will display data that belongs to the ID. In my case, the ID only has 1 value which it makes the auto post back not refresh the page. Is there any ways to make the labels show the data?</p>

<pre><code>  &lt;asp:DropDownList ID="DropDownList5" runat="server" 
                DataSourceID="SqlDataSource3" DataTextField="Id" DataValueField="Id" 
                Height="16px" Width="145px" AutoPostBack="True" 
                onselectedindexchanged="DropDownList5_SelectedIndexChanged"&gt;
            &lt;/asp:DropDownList&gt;
            &lt;asp:SqlDataSource ID="SqlDataSource3" runat="server" 
                ConnectionString="&lt;%$ ConnectionStrings:Connection %&gt;" 
                SelectCommand="SELECT [Id] FROM [Rsvp] WHERE (([Model] = @Model) AND ([Username] = @Username))"&gt;
                &lt;SelectParameters&gt;
                    &lt;asp:ControlParameter ControlID="DropDownList2" Name="Model" 
                        PropertyName="SelectedValue" Type="String" /&gt;
                    &lt;asp:ControlParameter ControlID="DropDownList3" Name="Username" 
                        PropertyName="SelectedValue" Type="String" /&gt;
                &lt;/SelectParameters&gt;
            &lt;/asp:SqlDataSource&gt;
</code></pre>
