Remarks

In general, an ItemsControl serves two roles. It can be used to present a fixed set of items, or it can be used to display a list obtained from data binding to an object. There are several controls that inherit from ItemsControl that you can use in your application, but you can also use an ItemsControl directly. For example, if you have a collection of data that you want to display as a nonselectable list, you can use an ItemsControl to contain the data. Regardless of whether you use the ItemsControl or a child class, you can use the ItemTemplate to specify the appearance of each item.

If you want to display a fixed list, populate Items with one or more FrameworkElement child objects, and leave DisplayMemberPath as the default empty string. Do not specify ItemsSource.

If you want to display data from an object source, specify ItemsSource to be a reference to an object. Usually you do this through a Binding declaration, and the resolution mechanism for the object being used as the binding source is potentially influenced by the acting DataContext. You can set DisplayMemberPath to be the name or path of the particular property that should be displayed as repeating data by using a default display for the returned object. Or you can leave DisplayMemberPath as the default empty string, and specify a DataTemplate for ItemTemplate. This last approach gives you more control of the visual representation of each item, and it also enables you to display multiple properties of each data-bound object within each item by using a layout that you define in the template.

Examples

The following example creates a page with several ListBox controls, which inherit from ItemsControl, configured in a variety of ways.

The following example creates an ItemsControl. By default, an ItemsControl lists items but does not have any other visual characteristics, such as chrome. The example specifies a ControlTemplate to give the ItemsControl a border. It also specifies a DataTemplate to specify the appearance of each item and an ItemsPanelTemplate to lay out the items horizontally.

<Grid>
  <Grid.Resources>
    <src:Tasks x:Key="myTodoList"/>
  </Grid.Resources>  
  <ItemsControl Margin="10" Width="400" 
            ItemsSource="{Binding Source={StaticResource myTodoList}}">
    <!--Use the Template property to specify a ControlTemplate to define
    the appearance of an ItemsControl. The ItemsPresenter uses the specified
    ItemsPanelTemplate (defined below) to layout the items. If an
    ItemsPanelTemplate is not specified, the default is used. (For ItemsControl,
    the default is an ItemsPanelTemplate that specifies a StackPanel that
    arranges items vertically.)-->
    <ItemsControl.Template>
      <ControlTemplate TargetType="ItemsControl">
        <Border BorderBrush="Aqua" BorderThickness="1" CornerRadius="15">
          <ItemsPresenter/>
        </Border>
      </ControlTemplate>
    </ItemsControl.Template>
    <!--Use the ItemsPanel property to specify an ItemsPanelTemplate
    that defines the panel that is used to hold the generated items.
    In other words, use this property if you want to affect
    how the items are laid out.-->
    <ItemsControl.ItemsPanel>
      <ItemsPanelTemplate>
        <StackPanel Orientation="Horizontal"/>
      </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>
    <!--Use the ItemTemplate to set a DataTemplate to define
    the appeatance of the data objects. This DataTemplate
    specifies that each data object appears with the Proriity
    and TaskName on top of a silver ellipse.-->
    <ItemsControl.ItemTemplate>
      <DataTemplate>
        <Grid Width="70" Margin="5">
          <Ellipse Fill="Silver"/>
          <StackPanel>
            <TextBlock Margin="3,3,3,0" FontSize="12" HorizontalAlignment="Center"
                   Text="{Binding Path=Priority}"/>
            <TextBlock Margin="3,0,3,7" FontSize="12" HorizontalAlignment="Center"
                   Text="{Binding Path=TaskName}"/>
          </StackPanel>
        </Grid>
      </DataTemplate>
    </ItemsControl.ItemTemplate>
  </ItemsControl>
</Grid>

public class Task : INotifyPropertyChanged
{
    private string name;
    private int priority;


    public event PropertyChangedEventHandler PropertyChanged;

    public Task()
    {
    }

    public Task(string name, int priority)
    {
        this.name = name;
        this.priority = priority;
    }

    public override string ToString()
    {
        return name.ToString();
    }

    public string TaskName
    {
        get { return name; }
        set
        {
            name = value;
            OnPropertyChanged("TaskName");
        }

    {
        PropertyChangedEventHandler handler = PropertyChanged;
        if (handler != null)
        {
            handler(this, new PropertyChangedEventArgs(info));
        }
    }

public class Tasks : ObservableCollection<Task>
{
    public Tasks()
        : base()
    {
        Add(new Task("Shopping", 2));
        Add(new Task("Laundry", 2));
        Add(new Task("Email", 1));
        Add(new Task("Clean", 3));
        Add(new Task("Dinner", 1));
    }
}

The previous example produces output that resembles the following illustration.
