<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:JC %>"         SelectCommand="SELECT distinct(CarModel) FROM [cars] where Carbrand=replace(@carbrand,'-',' ')">
<SelectParameters>             <asp:RouteParameter Name="carbrand" RouteKey="carbrand" />         </SelectParameters>
