    After photo gallery browsing it goes back to the first page

    Good Day

    in my Xamarin page i have a button that browse the gallery to allow a user to bind it to an image editor , after selecting the image , the page refreshes to the first page that led to this current page. i would like to make it keep it in the current page after image selection . below is the code on my button

    Code:
    async private void Btnupload_Clicked(object sender, EventArgs e)
            {
                GenericMethods.IS_IMAGE_SELECTON = true;
                    if (!CrossMedia.Current.IsPickPhotoSupported)
                    {
                        await DisplayAlert("Photos Not Supported", ":( Permission not granted to photos.", "OK");
                        return;
                    }
                    var file = await CrossMedia.Current.PickPhotoAsync(new Plugin.Media.Abstractions.PickMediaOptions
                    {
                        PhotoSize = Plugin.Media.Abstractions.PhotoSize.Medium
                    });
    
                    if (file == null)
                        return;
    
                    filePath = file.Path;
                    paths.Enqueue(filePath);
    
                    //Linux path 
                    readytosave = GenericMethods.StreamToByteArray(file.GetStream());
    
                    Uri uri = new Uri(file.Path);
                    filename = string.Empty;
                    if (uri.IsFile)
                    {
                        filename = System.IO.Path.GetFileName(uri.LocalPath);
                    }
                    var extension = filename.Split('.')[1].ToLower();
    
                    file_extension = extension;
    
                     imageEditor.Source = ImageSource.FromStream(() =>
                    {
                        var stream = file.GetStream();
                        return stream;
                    });
                imagepopup.IsOpen = true;
            }
    Thanks

    Re: After photo gallery browsing it goes back to the first page

    Display an ActionSheet with Prism.IPageDialogService to give choices to the user.

    Method for a button.

    Code:
    private async void AddImage() // This is your method for your button
    {
        string chosen = await _dialogService.DisplayActionSheetAsync("Which source do you want to use?", "Cancel", null, "Camera", "Galery");
        if (chosen == "Camera")
        {
            TakePhoto();
        }
        else if (chosen == "Galery")
        {
            PickPhoto();
        }
    }
    Implementation of TakePhoto()

    Code:
    private async void TakePhoto()
    {
        await CrossMedia.Current.Initialize();
    
        if (!CrossMedia.Current.IsCameraAvailable || !CrossMedia.Current.IsTakePhotoSupported)
        {
            await _dialogService.DisplayAlertAsync("Warning", "Camera not available", "OK");
            return;
        }
    
        _mediaFile = await CrossMedia.Current.TakePhotoAsync(new Plugin.Media.Abstractions.StoreCameraMediaOptions
        {
            SaveToAlbum = true,
            Directory = "Sample",
            Name = "sample" + DateTime.Now.ToLocalTime().ToString("yyyyMMddHHmmss") + ".jpg"
        });
    
        if (_mediaFile == null)
        {
            return;
        }
    
        ImageButtonAddGroup = _mediaFile.Path;
    }
    Implementation of PickPhoto()

    Code:
    private async void PickPhoto()
    {
        await CrossMedia.Current.Initialize();
    
        if (!CrossMedia.Current.IsPickPhotoSupported)
        {
            await _dialogService.DisplayAlertAsync("Warning", "Camera not available", "OK");
            return;
        }
    
        _mediaFile = await CrossMedia.Current.PickPhotoAsync();
        if (_mediaFile == null)
        {
            return;
        }
        ImageButtonAddGroup = _mediaFile.Path;
    }
    Using this code you can select a pic from gallery and take a pic from camera.
