How do I set ListBox item height in Window Resources?

Question

This

<ListBox x:Name="gLBxM">
    <ListBox.ItemContainerStyle>
        <Style TargetType="ListBoxItem">
            <Setter Property="Height" Value="21" />
        </Style>
    </ListBox.ItemContainerStyle>
</ListBox> 

sets the ListBox item height for a specific ListBox. What do add to

<Window.Resources> 

so it applies to all ListBox'es?

Answer 1

The following implicit Style will be applied to all ListBoxItems in the window unless you set the ItemContainerStyle property to some other Style:

<Window.Resources>
    <Style TargetType="ListBoxItem">
        <Setter Property="Height" Value="100" />
    </Style>
</Window.Resources>
...
<ListBox x:Name="gLBxM" />
