File Picker in Windows Phone 8.1

c#, windows-phone-8.1

Solution

I think you can handle the OnActivated event even in the page where you required. Something like this

CoreApplicationView view = CoreApplication.GetCurrentView();

ImagePath=string.Empty;
FileOpenPicker filePicker = new FileOpenPicker();
filePicker.SuggestedStartLocation = PickerLocationId.PicturesLibrary;
filePicker.ViewMode = PickerViewMode.Thumbnail;

// Filter to include a sample subset of file types
filePicker.FileTypeFilter.Clear();
filePicker.FileTypeFilter.Add(".bmp");
filePicker.FileTypeFilter.Add(".png");
filePicker.FileTypeFilter.Add(".jpeg");
filePicker.FileTypeFilter.Add(".jpg");

filePicker.PickSingleFileAndContinue();
view.Activated += viewActivated; 

private void viewActivated(CoreApplicationView sender, IActivatedEventArgs args1)
{
    FileOpenPickerContinuationEventArgs args = args1 as FileOpenPickerContinuationEventArgs;

    if (args != null)
    {
        if (args.Files.Count == 0) return;

        view.Activated -= viewActivated;
        storageFileWP = args.Files[0];

    }
}

When you select the files from the picker the above method will be called. I believe it helps you.

Problem

I want to pick an image from my pictures album in windows phone 8.1 . For this I used this code but its gives error ``` private async void gallery_Tapped(object sender, TappedRoutedEventArgs e) { FileOpenPicker opener = new FileOpenPicker(); opener.ViewMode = PickerViewMode.Thumbnail; opener.SuggestedStartLocation = PickerLocationId.PicturesLibrary; opener.FileTypeFilter.Add(".jpg"); opener.FileTypeFilter.Add(".jpeg"); opener.FileTypeFilter.Add(".png"); StorageFile file = await opener.PickSingleFileAsync(); if (file != null) { // We've now got the file. Do something with it. var stream = await file.OpenAsync(Windows.Storage.FileAccessMode.Read); var bitmapImage = new Windows.UI.Xaml.Media.Imaging.BitmapImage(); await bitmapImage.SetSourceAsync(stream); var decoder = await Windows.Graphics.Imaging.BitmapDecoder.CreateAsync(stream); MyImage.Source=bitmapImage; } else { //OutputTextBlock.Text = "The operation may have been cancelled."; } } ``` Error
