Using an asp:DropDownList control on a webform. The databound has id, lastname, firstname fields, but no fullname (lastname + ', ' + firstname). I need the fullname however I am not allowed to alter the sql query to return the fullname...so I think I need to find an alternative to the datatextfield.
<asp:DropDownList ID="ddlFullName" runat="server" DataTextField="???" DataValueField="ID"></asp:DropDownList>
