put security to dropdown menu

Question

good!! I have a drop down menu

 <div id="topnav">  
      <ul>  
        <li class="active"><a href="PageLogin.aspx">Acceso</a></li>  
        <li><a href="#" >Style Demo</a></li>  
        <li><a href="#">Full Width</a></li>  
        <li><a href="#">Seguridad</a>  
          <ul>  
            <li><a href="PageAltaEmpleado.aspx">Alta de Usuario</a></li>  
            <li><a href="PageBuscaUsuario.aspx">Busca Usuarios</a></li>  
            <li><a href="PagePuertas.aspx">Puertas ABM</a></li>  
            <li><a href="PageAdmPuertas.aspx">Administra Puerta</a></li>  
            <li><a href="PageUsuarios.aspx">prueba</a></li>  
            <li><a href="PageAccesos.aspx">Administra Accesos</a></li>  
            <li><a href="PageAutocompletado.aspx">Autocompletado </a></li>  
            <li><a href="#">Link 8</a></li>  
            <li><a href="#">Link 9</a></li>  
            <li><a href="#">Link 10</a></li>  
            <li><a href="#">Link 11</a></li>  
            <li><a href="#">Link 12</a></li>  
            <li><a href="#">Link 13</a></li>  
  
          </ul>  
        </li>  
        <li class="last" ><a href="#">A Long Link Text</a></li>  
          <asp:Label ID="MuestraFecha" runat="server"></asp:Label>  
      </ul>  
    </div>  
  

by SQL I bring the security of the doors that the user can see

DataTable access = (DataTable)Session["MyAccess"];  

return this result

I would like to know if the item (<li> <a href="#"> Link 8 </a> </li>) can be given the code (example 2055) and then buy it with what I bring from the database and I save it in the session variable, and then this line, remove it, enable, disable, with javascript or somehow ???

de esta manera el usuario no podra acceder a esa linea del menu desplegable o no la ve.

Answer 1

there I found a solution

in the drop-down menu I put

<div id="topnav">
      <ul>
        <li class="active"><a href="#">Home</a></li>
        <li><a id="A2047" runat="server" href="WebForm2.aspx">PUERTAS</a></li>
        <li><a id="A2048" runat="server" href="#">URUARIO</a></li>
        <li><a id="A2049" runat="server" href="#">SEGURIDAD</a>
          <ul>
            <li><a id="A2050" runat="server" href="#">Link 1</a></li>
            <li><a id="A2051" runat="server" href="#">Link 2</a></li>
            <li><a id="A2052" runat="server" href="#">Link 3</a></li>
          </ul>

then the code looked for the menu item and took it out

Page_Load

1º

            A2047.Visible = false;
            A2048.Visible = false;
            A2049.Visible = false;

then with the accesses that the user can see, I visualize them

 DataTable access = (DataTable)Session["MyAccess"];

//esto recorre la tabla (Datatable) 

            for (int i = 0; i < access.Rows.Count; i++)
            {
                string door = access.Rows[i]["D_NO"].ToString();

                if (door == "2049")
                {
                    A2049.Visible = true;

                }
             }

or it can also be done by Css

 //A2049.Attributes["class"] = "yourCssClass";
