Site,Master Navigation

Oct 05, 2020 04:21 PM|NJ2|LINK

I've created a sample application where Site.Master.aspx has all navigations and Login.aspx/Register.aspx etc. are in Account folder.
By default, all menu options are enabled and I don't want all enabled unless user has successfully logged in. Once a user logs in then the Home page should be displayed and the navigation bar should enable "Home", "Contact" and "About".

How do I get it done?

The following is the code for Page.Master.aspx and Page.Master.aspx.c but you should be able to create a default web form application which should give you the same.

I have assigned an ID (id="myDiv") to DIV but the following code still won't work, I get an Exception "dv was null"

<div id="myDiv" class="navbar-collapse collapse">
                    <ul id="ulMenu" class="nav navbar-nav">
                        <li><a runat="server" href="~/">Home</a></li>--%>
                        <li><a runat="server" href="~/About">Home</a></li>
                        <li><a runat="server" href="~/Contact">About</a></li>
                   </ul>

OK, I have partially resolved the issue and hide/show the "LoginView" control but still trying to figure out how to do the same for "ulMenu"

<ul id="ulMenu" class="nav navbar-nav">
      <li><a runat="server" href="~/">Home</a></li>--%>
      <li><a runat="server" href="~/About">Home</a></li>
        <li><a runat="server" href="~/Contact">About</a></li>
</ul>

The following is what I did to hide/display "LoginView"

            LoginView navLoginRegister2 = (LoginView)this.Master.FindControl("lvLoginRegister");
            if (navLoginRegister2 != null)
            {
                navLoginRegister2.Visible = true;
            }
