#132 – Inherited Property Values Pass Through All Elements

When an element looks up the element tree for an inherited property value, it doesn’t stop when it hits an element that doesn’t define that particular property.  The element “looks” all of the way up the tree, to the root element.

In the example below, we set a value for the FontStyle in the top-level Window element.  That value is inherited by the Button elements further down the tree, even though their immediate parent–the StackPanel–does not have a FontStyle property.

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:m="clr-namespace:PersonLib;assembly=PersonLib"
        Title="MainWindow" Height="350" Width="525" FontStyle="Italic">
    <StackPanel Orientation="Vertical">
        <Button Content="Run" Height="23" Width="75" />
        <Button Content="Skip" Height="23" Width="75" />
    </StackPanel>
</Window>
