Question

My ListBox.SelectedValue returns the first selected item and not the currently selected item. (Currently selected item means that aside from the selected ITEMS, I am also displaying the last item selected)

My SelectionMode this time is Multiple not Single.

private void ListBoxSource_SelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        var fileSelected = (FileFound)this.ListBoxSource.SelectedValue; 
        BitmapImage bmpImage = new BitmapImage();
        bmpImage.BeginInit();
        bmpImage.UriSource = new Uri(fileSelected.FileFullName, UriKind.Absolute);
        bmpImage.EndInit();

        Image1.Source = bmpImage;

     }

Now, instead of doing it on the event, I tried Binding my Image control to the ListBoxSource BUT nothing is displayed.

 Source="{Binding ElementName=ListBoxSource, Path=SelectedItems

Is theres a chance to bind it? or what is wrong with my SelectionChangedEvent code?

Answer 1

To get the last selected item, you’ll want the last index of the SelectedItems property.

var lb = (sender as ListBox);
lb.SelectedItems[lb.SelectedItems.Count - 1];

EDIT

To get the last selected item as a FileFound object, I think you want this:

var lb = (sender as ListBox);
FileFound lastSelectedFile = 
                 (FileFound)lb.SelectedItems[lb.SelectedItems.Count - 1];
