I taken two Images & added event (MouseButtonDown) for them.
When first
image handles event to open Gallery. Second
image handles events for open camera.
When user has choosed his
image from the gallery, I want to navigate to next page. Its navigates. But before completing navigation process, it displays MainPage & then moves toward next page. I didnt want to display the MainPage once user chooses the
image from the gallery.
Plz help.
Thanks in advance.
public partial class MainPage : PhoneApplicationPage
{
PhotoChooserTask objPhotoChooser;
CameraCaptureTask cameraCaptureTask;
// Constructor
public MainPage()
{
InitializeComponent();
objPhotoChooser = new PhotoChooserTask();
objPhotoChooser.Completed += new EventHandler<PhotoResult>(objPhotoChooser_Completed);
cameraCaptureTask = new CameraCaptureTask();
cameraCaptureTask.Completed += new EventHandler<PhotoResult>(objCameraCapture_Completed);
}
void objPhotoChooser_Completed(object sender, PhotoResult e)
{
if (e != null && e.TaskResult == TaskResult.OK)
{
//Take JPEG stream and decode into a WriteableBitmap object
App.CapturedImage = PictureDecoder.DecodeJpeg(e.ChosenPhoto);
//Delay navigation until the first navigated event
NavigationService.Navigated += new NavigatedEventHandler(navigateCompleted);
}
}
void navigateCompleted(object sender, EventArgs e)
{
//Do the delayed navigation from the main page
this.NavigationService.Navigate(new Uri("/ImageViewer.xaml", UriKind.RelativeOrAbsolute));
NavigationService.Navigated -= new NavigatedEventHandler(navigateCompleted);
}
void objCameraCapture_Completed(object sender, PhotoResult e)
{
if (e.TaskResult == TaskResult.OK)
{
//Take JPEG stream and decode into a WriteableBitmap object
App.CapturedImage = PictureDecoder.DecodeJpeg(e.ChosenPhoto);
//Delay navigation until the first navigated event
NavigationService.Navigated += new NavigatedEventHandler(navigateCompleted);
}
}
protected override void OnBackKeyPress(System.ComponentModel.CancelEventArgs e)
{
e.Cancel = true;
}
private void image1_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
objPhotoChooser.Show();
}
private void image2_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
cameraCaptureTask.Show();
}
