Below is my implementation. Clicking on button does nothing. How can I use FileOpenPicker to display only MP3 files? Though it shows me videos (MP4) as well as images (JPEG, PNG) if I set file type filter as only "PNG". Is there no effect of FileTypeFilter?
private void btnPick_Click(object sender, Windows.UI.Xaml.RoutedEventArgs e)
{
FileOpenPicker openPicker = new FileOpenPicker();
openPicker.FileTypeFilter.Add(".mp3");
App.ContinuationEventArgsChanged += App_ContinuationEventArgsChanged;
openPicker.PickMultipleFilesAndContinue();
}
private void App_ContinuationEventArgsChanged(object sender, IContinuationActivatedEventArgs e)
{
App.ContinuationEventArgsChanged -= App_ContinuationEventArgsChanged;
var openFileArgs = e as FileOpenPickerContinuationEventArgs;
foreach (var file in openFileArgs.Files)
{
//tb is TextBlock
tb.Text = file.Name + "\n";
}
}
