How to hide a sidebar on a login page using server events

Question

I have a website made with ASP.NET Maker that has a login page that includes a sidebar, which should be hidden when the user is not logged in. What is the best way to implement this functionality using server events?

Answer 1

the login page could use a different layout, or the layout could check for authentication before rendering the sidebar.

See the code of Views/Shared/_LoginPartial.cshtml. It will provide you with a clue to hide a sidebar from anonymous users.

The code uses SignInManager.IsSignedIn(User) to judge if the user is logged in as follows:

@using Microsoft.AspNetCore.Identity
@inject SignInManager<IdentityUser> SignInManager
@inject UserManager<IdentityUser> UserManager

<ul class="navbar-nav">
@if (SignInManager.IsSignedIn(User))
{
    <li class="nav-item">
        <a  class="nav-link text-dark" asp-area="Identity" asp-page="/Account/Manage/Index" title="Manage">Hello @User.Identity?.Name!</a>
    </li>
    <li class="nav-item">
        <form  class="form-inline" asp-area="Identity" asp-page="/Account/Logout" asp-route-returnUrl="@Url.Action("Index", "Home", new { area = "" })">
            <button  type="submit" class="nav-link btn btn-link text-dark">Logout</button>
        </form>
    </li>
}
else
{
    <li class="nav-item">
        <a class="nav-link text-dark" asp-area="Identity" asp-page="/Account/Register">Register</a>
    </li>
    <li class="nav-item">
        <a class="nav-link text-dark" asp-area="Identity" asp-page="/Account/Login">Login</a>
    </li>
}
</ul>
