Hi Guys, I have loaded a collection of images in the listBox and I display them in the ImageBox for further modification when I click on each image.
I have a button to delete the image, when i use the below function I'm getting a message, 'Image is being used'.
How can i delete the image & select another image? Thank you very much for your help & support.
Delete Function:
private void bDeletePhoto_Click(object sender, RoutedEventArgs e)
{
currImgHandler.ClearImage();
ImageFileCollectionViewModel viewModel = imageListBox.DataContext as ImageFileCollectionViewModel;
if (viewModel != null)
{
ImageFileViewModel image = imageListBox.SelectedItem as ImageFileViewModel;
if (image != null)
{
//remove physical file from disk:
File.Delete(image.FileName);
//remove item from ObservableCollection:
viewModel.AllImages.Remove(image);
}
}
}ListBox Select Item & display in the Image:
CurrentImageHandler currImgHandler;
private string saveFilname;
private void showImage(object sender, SelectionChangedEventArgs args)
{
ListBox list = ((ListBox)sender);
if (list != null)
{
int index = list.SelectedIndex;
if (index >= 0)
{
ImageFileViewModel image = imageListBox.SelectedItem as ImageFileViewModel;
if ((image != null) )
{
Uri uriSource = new Uri(image.FileName, UriKind.RelativeOrAbsolute);
ViewedPhoto.Source = new BitmapImage(uriSource);
ViewedCaption.Content = image.ShortName.ToString();
saveFilname = image.FileName.ToString();
currImgHandler.CurrentFileHandler.Load(saveFilname);
PaintImage();
}
}
}
}
private void PaintImage()
{
System.IO.MemoryStream stream = new System.IO.MemoryStream();
currImgHandler.CurrentBitmap.Save(stream, System.Drawing.Imaging.ImageFormat.Bmp);
stream.Position = 0;
byte[] data = new byte[stream.Length];
stream.Read(data, 0, Convert.ToInt32(stream.Length));
BitmapImage bmapImage = new BitmapImage();
bmapImage.BeginInit();
bmapImage.StreamSource = stream;
bmapImage.EndInit();
ViewedPhoto.Source = bmapImage; //ImageBox
}
