Valor de propiedad

The ItemContainerGenerator that is associated with this control. The default value is referencia null (Nothing en Visual Basic).

An ItemContainerGenerator is responsible for generating the user interface (UI) for its host, such as an ItemsControl. It maintains the association between the items in the data view of the control and the corresponding UIElement objects.

If you need to get a specific ListBoxItem at a particular index in a ListBox you can use ItemContainerGenerator. The following example shows the ListBox and its items.

<ListBox Margin="10,0,0,5" Name="lb" VerticalAlignment="Top" Grid.Column="0" Grid.Row="2">
    <ListBoxItem>Item 0</ListBoxItem>
    <ListBoxItem>Item 1</ListBoxItem>
    <ListBoxItem>Item 2</ListBoxItem>
    <ListBoxItem>Item 3</ListBoxItem>
</ListBox>

This example shows how to retrieve the item by specifying the index of the item in the ContainerFromIndex property.

private void GetIndex0(object sender, RoutedEventArgs e)
{
  ListBoxItem lbi = (ListBoxItem)
      (lb.ItemContainerGenerator.ContainerFromIndex(0));
  Item.Content = "The contents of the item at index 0 are: " +
      (lbi.Content.ToString()) + ".";
}

Once you have retrieved the list box item you can do things such as display the contents of the item as shown in this example.

Item.Content = "The contents of the item at index 0 are: " +
    (lbi.Content.ToString()) + ".";
