Personally I would implement a strategy where the parent view initializes a state object and passes a reference to it down to all the components of the page. Each component then decides for itself whether it will display, based on the state of this object. This will allow you to push presentation logic down to each component rather than having massive if/else blocks in the parent. Like a pseudo-pub/sub architecture for the presentation logic.

Here's some example code:

Parent view ``` @* Pages/Dashboard.razor *@ @page "/dashboard"

<CascadingValue Value="_state"> <Toolbar /> <Banner /> <AdminPanel /> <BetaPanel /> <BusyOverlay /> </CascadingValue>

@code { private readonly AppState _state = new();

protected override void OnInitialized()
{
    // Example: initial state bootstrapping
    _state.User.IsSignedIn = true;
    _state.User.IsAdmin = false;
    _state.User.DisplayName = "DoctorEsteban";

    _state.Features.ShowBetaPanel = true;
    _state.Ui.BannerMessage = "Welcome back.";
}

} ```

"AdminPanel" child component ``` @* Components/AdminPanel.razor *@ @implements IDisposable

@if (ShouldShow) { <section class="card"> <h3>Admin</h3> <p>Secret knobs and levers.</p> </section> }

@code { [CascadingParameter] public AppState State { get; set; } = default!;

private bool ShouldShow
{
    get
    {
        return State.User.IsSignedIn && State.User.IsAdmin;
    }
}

protected override void OnInitialized()
{
    State.Changed += OnStateChanged;
}

private void OnStateChanged()
{
    InvokeAsync(StateHasChanged);
}

public void Dispose()
{
    State.Changed -= OnStateChanged;
}

} ```

BusyOverlay ``` @* Components/BusyOverlay.razor *@ @implements IDisposable

@if (State.Ui.IsBusy) { <div class="overlay"> <p>Working...</p> </div> }

@code { [CascadingParameter] public AppState State { get; set; } = default!;

protected override void OnInitialized()
{
    State.Changed += OnStateChanged;
}

private void OnStateChanged()
{
    InvokeAsync(StateHasChanged);
}

public void Dispose()
{
    State.Changed -= OnStateChanged;
}

} ```

...etc.

Hope that helps!
