Accessing WPF UserControl child element property

Question

Let\'s say I have a UserControl with several child controls

Answer 1

Try like this (although it's not the best practice to style controls in their parent control):

<local:AnyControl>
    <local:AnyControl.Resources>
        <Style TargetType="{x:Type Label}">
            <Setter Property="Background" Value="Red" />
        </Style>
    </local:AnyControl.Resources>
</local:AnyControl>

It sets the background property for all controls of a given type inside your UserControl. If you want to change it for a control selected by a name, you can do something like that (change Value="Test" to your control's name):

<local:AnyControl>
    <local:AnyControl.Resources>
        <Style TargetType="{x:Type Label}">
            <Style.Triggers>
                <Trigger Property="Name" Value="Test">
                    <Setter Property="Background" Value="Red" />
                </Trigger>
            </Style.Triggers>
        </Style>
    </local:AnyControl.Resources>
</local:AnyControl>
