How to assign a SiteMapDataSource object to a user control property

I have the following user control:

public partial class UserControlLeftMenu : System.Web.UI.UserControl
{
    private SiteMapDataSource _siteMapDataSrc;

    public SiteMapDataSource DataSource
    {
        get { return _siteMapDataSrc; }
        set { _siteMapDataSrc = value; }
    }

  }

How do I assign the property on an .aspx page?

...
<%@ Register src="UserControlLeftMenu.ascx" tagname="UserControlLeftMenu" tagprefix="bvt" %>
...
<asp:SiteMapDataSource ID="WebSiteMapDataSource" runat="server" />
...

Neither of these work, both produce compile errors:
<bvt:UserControlLeftMenu ID="UserControlLeftMenu1" runat="server" DataSource=WebSiteMapDataSource/>
<bvt:UserControlLeftMenu ID="UserControlLeftMenu1" runat="server" DataSource="WebSiteMapDataSource"/>

What you need to remember is that in its current form you are actually passing in the string "WebSiteMapDataSource", not the control itseld.

 You have 2 options to get this working :

1) Programatically assign the datasource in the codebehind:

UserControlLeftMenu1.DataSource = WebSiteMapDataSource

2) Change the type of your parameter to String (and for the sake of good practice rename it DataSourceID), then in your code use a recursive FindControl on the usercontrol's Page  property using that string value to find the datasource

For SiteMap alone why do you required a seperate user control?
