WPF/C# Binding custom object list data to a ListBox?

Question

I've ran into a bit of a wall with being able to bind data of my custom object list to a ListBox in WPF.

This is the custom object:

public class FileItem {     public string Name { get; set; }     public string Path { get; set; } } 

And this is the list:

private List<FileItem> folder = new List<FileItem>(); public List<FileItem> Folder { get { return folder; } } 

The list gets populated and maintained by a FileSystemWatcher as files get moved around, deleted, renamed, etc. All the list does is keeps tracks of names and paths.

Here's what I have in the MainWindow code-behind file (it's hard coded for testing purposes for now):

FolderWatcher folder1 = new FolderWatcher(); folder1.Run(@"E:\MyApp\test", "*.txt");  listboxFolder1.ItemsSource = folder1.Folder; 

Here's my XAML portion:

<ListBox x:Name="listboxFolder1" Grid.Row="1" BorderThickness="0"           ItemsSource="{Binding}"/> 

Unfortunately, the only thing that gets displayed is MyApp.FileItem for every entry. How do I display the specific property such as name?

You will need to define the ItemTemplate for your ListBox

    <ListBox x:Name="listboxFolder1" Grid.Row="1" BorderThickness="0"       ItemsSource="{Binding}">        <ListBox.ItemTemplate>          <DataTemplate>            <TextBlock Text="{Binding Name}"/>          </DataTemplate>        </ListBox.ItemTemplate>      </ListBox>
