I have an asp:dropdown populated from a sqldatasource control and it works great.  However, I need to add 1 more listitem that is not pulled from the query to put in the dropdown but it does not show up.  How can I do this?
<asp:DropDownList ID="DropDownList1" runat="server" DataSourceID="sdsMember" DataTextField="MEMBER_SNAME" DataValueField="MEMBER_ID">
                                    
<asp:ListItem Text="All Members" Value="0" Selected="True"></asp:ListItem>
                                    
</asp:DropDownList>
                                    
<asp:SqlDataSource ID="sdsMember" runat="server" ConnectionString="<%$ ConnectionStrings:DBSFL %>" SelectCommand="select MEMBER_SNAME, MEMBER_ID from MEMBER order by MEMBER_SNAME ASC"></asp:SqlDataSource>

In case it wasn't clear, the output on the page is all of the items from the select statement of the sqldatasource but the asp:listitem "All Members" does not show up - looking to see how this is done.  Thanks!

Add AppendDataBoundItems="true" to asp:DropDownList

<asp:DropDownList ID="DropDownList1" runat="server" DataSourceID="sdsMember" DataTextField="MEMBER_SNAME" DataValueField="MEMBER_ID" AppendDataBoundItems="true">
