V2 update for popup

[TheR7angelo]

using CommunityToolkit.Maui.Extensions;
using Serilog;

namespace MyExpenses.Smartphones.ContentPages.CustomPopups.CustomPopupActivityIndicator;

public static class CustomPopupActivityIndicatorHelper
{
    private static CustomPopupActivityIndicator? _customPopupActivityIndicator;
    private static bool _isOpen;

    public static void ShowCustomPopupActivityIndicator(this Page contentPage, string messageToDisplay)
    {
        _customPopupActivityIndicator = new CustomPopupActivityIndicator { LabelTextToDisplay = messageToDisplay };
        _customPopupActivityIndicator.Opened += CustomPopupActivityIndicatorOnOpened;
        _customPopupActivityIndicator.Closed += CustomPopupActivityIndicatorOnClosed;
        contentPage.ShowPopup(_customPopupActivityIndicator);
    }

    private static void CustomPopupActivityIndicatorOnClosed(object? sender, EventArgs e)
    {
        Log.Information("CustomPopupActivityIndicator closed");
        _isOpen = false;
    }

    private static void CustomPopupActivityIndicatorOnOpened(object? sender, EventArgs e)
    {
        Log.Information("CustomPopupActivityIndicator opened");
        _isOpen = true;
    }

    public static void CloseCustomPopupActivityIndicator()
    {
        Log.Information("CustomPopupActivityIndicator close requested");
        _customPopupActivityIndicator?.CloseAsync();
    }
}

In Popup V1 I used this code to open a popup to say a waiting message to the user and after a load I close the popup but in V2 the popup opens too late and the close request does nothing.
If I click outside the popup to close it manually, my application crashes saying there is no popup open.

Can you help me understand what the problem is, whether it's my code or a V2 bug?

With CoPilot hep, you need to do await, so you wait for the opening the popup.

CoPilot suggested code:

using CommunityToolkit.Maui.Views;
using Microsoft.Maui.ApplicationModel; // for MainThread if needed

public static class CustomPopupActivityIndicatorHelper
{
    private static CustomPopupActivityIndicator? _popup;

    public static async Task ShowCustomPopupActivityIndicatorAsync(this Page contentPage, string message)
    {
        _popup = new CustomPopupActivityIndicator { LabelTextToDisplay = message };
        _popup.Opened += OnOpened;
        _popup.Closed += OnClosed;

        // Await the Show so the popup is fully opened before code continues
        await contentPage.ShowPopupAsync(_popup, PopupOptions.Empty);
    }

    public static async Task CloseCustomPopupActivityIndicatorAsync()
    {
        if (_popup is null) return;

        // Ensure we run CloseAsync on the UI thread
        await MainThread.InvokeOnMainThreadAsync(async () =>
        {
            await _popup.CloseAsync();
        });
    }

    private static void OnOpened(object? s, EventArgs e)
    {
        // handle opened
    }

    private static void OnClosed(object? s, EventArgs e)
    {
        if (_popup != null)
        {
            _popup.Opened -= OnOpened;
            _popup.Closed -= OnClosed;
            _popup = null;
        }
    }
}

Hello,
If I do as you say, my background change process no longer works at all.
I found another solution: I use a library that does it, opens a pop-up, and performs a task in the background.
Thank you for your attention in asking an AI anyway.

@TheR7angelo what is the library called?

[TheR7angelo]

public static async Task ShowCustomPopupActivityIndicatorAsync(this Page contentPage, string title, string messageToDisplay, Func<Task> function)
    {
        using (await contentPage.DisplayProgressAsync(title, messageToDisplay))
        {
            await function.Invoke();
        }
    }

The library is Uranium UI

@TheR7angelo good work. Now I understand what you wanted to do. Controls.UserDialogs.Maui library is also an alternative.
