How can you DisplayAlert from a .NET Maui ContentView?

Question

I am trying to do something similar to:

await DisplayAlert("Alert", "You have been alerted", "OK");

The issue is the button that is triggering this is on a ContentView, not a ContentPage. I understand why it is not available on the view (sort of), but there must be a way to trigger an alert dialogue if your UI object is part of a view I would think.

Any ideas?

Thanks.

Answer 1

Use

App.Current.Mainpage.DisplayAlert(…);

Answer 2

Just for the people wondering how to do something similar in .NET Maui Blazor, this is how I got an alert in .NET Maui Blazor.

It is similar to the answer, but we use Application.Current inside namespace Microsoft.Maui.Controls here.

Example usage, note the usage of async/await :

   private async Task OnInputFile(InputFileChangeEventArgs args)
    {
        var imageSaveModel = await ImageSaveService.SaveImage(args.File);
        Model = new IndexModel(imageSaveModel);
        await Application.Current.MainPage.DisplayAlert($"MAUI Blazor ImageAnalyzer app App", $"Wrote file to location : {Model.SavedFilePath} Size is: {Model.FileSize} kB", "Ok", "Cancel");
    }
