Use this method

C#

public static string RenderControl(Control ctrl)
    {
        StringBuilder sb = new StringBuilder();
        StringWriter tw = new StringWriter(sb);
        HtmlTextWriter hw = new HtmlTextWriter(tw);
        ctrl.RenderControl(hw);
        return sb.ToString();
    }

and call function as

C#

Msg.Body += RenderControl(datalist1);

Hope it will resolve your problem.
