How to change a telerik: RadMenu to a one .NET component?

I'm trying to change a menu made in Telerik to .NET components. I leave you an example of code.

<div id="MenuBody" style="float: left; width: 15%; height: 210px;">

           <%-- <telerik:RadMenu ID="RadMenu1" runat="server" Flow="Vertical"
                Font-Bold="False" Font-Names="Leelawadee UI" Font-Size="10pt" EnableRoundedCorners="True"
                DataFieldID="IdMenu" DataFieldParentID="MenuP" DataNavigateUrlField="Url_Archivo" DataTextField="Descripcion"
                DataSourceID="SqlMenu" RenderMode="Lightweight" Style="top: 0px; left: 0px; height: 36px" EnableAriaSupport="True">
                <DefaultGroupSettings OffsetX="5" />
            </telerik:RadMenu>--%>

Any ideas?
