Metadata properties set to true


You use this property or the ItemContainerStyleSelector property to set a style to affect the appearance of the elements that contain the data items. For example, for ListBox, the generated containers are ListBoxItem controls; for ComboBox, they are ComboBoxItem controls.

The ItemsControl provides great flexibility for visual customization, and therefore, provides many styling and templating properties. To affect the layout of the items, you use the ItemsPanel property. If you are using grouping on your control, you can use GroupStyle or GroupStyleSelector. You use the ItemTemplate or the ItemTemplateSelector to specify the visualization of the data objects. For more information about when to specify an ItemTemplate, see Data Templating Overview.

The following example is designed to illustrate the function of the different styling and templating related properties provided by the ItemsControl. The ItemsControl in this example is bound to a collection of Task objects. For demonstration purposes, the styles and templates in this example are all declared inline.

<ItemsControl Margin="10"
              ItemsSource="{Binding Source={StaticResource myTodoList}}">
  <!--The ItemsControl has no default visual appearance.
      Use the Template property to specify a ControlTemplate to define
      the appearance of an ItemsControl. The ItemsPresenter uses the specified
      ItemsPanelTemplate (see 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.-->
    <ControlTemplate TargetType="ItemsControl">
      <Border BorderBrush="Aqua" BorderThickness="1" CornerRadius="15">
  <!--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.-->
      <WrapPanel />
  <!--Use the ItemTemplate to set a DataTemplate to define
      the visualization of the data objects. This DataTemplate
      specifies that each data object appears with the Proriity
      and TaskName on top of a silver ellipse.-->
        <Style TargetType="TextBlock">
          <Setter Property="FontSize" Value="18"/>
          <Setter Property="HorizontalAlignment" Value="Center"/>
        <Ellipse Fill="Silver"/>
          <TextBlock Margin="3,3,3,0"
                     Text="{Binding Path=Priority}"/>
          <TextBlock Margin="3,0,3,7"
                     Text="{Binding Path=TaskName}"/>
  <!--Use the ItemContainerStyle property to specify the appearance
      of the element that contains the data. This ItemContainerStyle
      gives each item container a margin and a width. There is also
      a trigger that sets a tooltip that shows the description of
      the data object when the mouse hovers over the item container.-->
      <Setter Property="Control.Width" Value="100"/>
      <Setter Property="Control.Margin" Value="5"/>
        <Trigger Property="Control.IsMouseOver" Value="True">
          <Setter Property="Control.ToolTip"
                  Value="{Binding RelativeSource={x:Static RelativeSource.Self},
