커스텀컨트롤 DependencyProperty 설정

Q&A
1

xaml과 cs로 커스텀컨트롤을 제작하고 있습니다. 하지만 이제 시작하는 단계다보니 어려운 것이 많네요.
제 질문은 DropShadowEffect BlurRadius=“20” ShadowDepth=“13” Direction=“315” Color=“#33D1D9E6”
여기 부분의 속성값들을 DependencyProperty로 설정하여 다른 xaml에서 속성값 설정하듯이 하는 방법이 어떻게 되는지 입니다.
상위의 Border에서는 templateBinding을 사용해서 설정값이 반영되는지 확인했으나 같은 방법으로 시도해보아도 적용되지 않네요..

다음은 저의 코드입니다.
GlassmorphismButton.xaml

<Style TargetType="{x:Type local:GlassmorphismButton}" BasedOn="{StaticResource {x:Type Button}}">
    <Setter Property="Background" Value="{StaticResource DefaultBackground}"/>
    <Setter Property="Foreground" Value="Black"/>
    <Setter Property="Width" Value="100"/>
    <Setter Property="Height" Value="100"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type local:GlassmorphismButton}">
                <Border x:Name="FirstBorder" Background="{TemplateBinding Background}"  CornerRadius="{TemplateBinding BorderCornerRadius}" >
                    <Border.Effect>
                        <DropShadowEffect BlurRadius="20" ShadowDepth="13" Direction="315" Color="#33D1D9E6"/>
                    </Border.Effect>

GlassmorphismButton.cs

 public class GlassmorphismButton : Button
 {
     public static readonly DependencyProperty BorderCornerRadiusProperty =
         DependencyProperty.Register(
             "BorderCornerRadius",
             typeof(CornerRadius),
             typeof(GlassmorphismButton),
             new PropertyMetadata());

     public CornerRadius BorderCornerRadius
     {
         get => (CornerRadius)GetValue(BorderCornerRadiusProperty);
         set => SetValue(BorderCornerRadiusProperty, value);
     }

     public static readonly DependencyProperty BlurRadiusProperty =
         DependencyProperty.Register(
             "BlurRadius",
             typeof(double),
             typeof(GlassmorphismButton),
             new PropertyMetadata());

     public double BlurRadius
     {
         get => (double)GetValue(BlurRadiusProperty);
         set => SetValue(BlurRadiusProperty, value);
     }


     static GlassmorphismButton()
     {
         DefaultStyleKeyProperty.OverrideMetadata(typeof(GlassmorphismButton), new FrameworkPropertyMetadata(typeof(GlassmorphismButton)));
     }


 }

고수님들의 도움을 기다리겠습니다. 감사합니다!

<Setter Property="Template">
	<Setter.Value>
		<ControlTemplate TargetType="{x:Type local:GlassmorphismButton}">
			<Border
				x:Name="FirstBorder"
				Background="{TemplateBinding Background}"
				CornerRadius="{TemplateBinding BorderCornerRadius}">
				<Border.Effect>
					<DropShadowEffect
						BlurRadius="{Binding BlurRadius, RelativeSource={RelativeSource TemplatedParent}}"
						Direction="315"
						ShadowDepth="13"
						Color="#33D1D9E6" />
				</Border.Effect>
			</Border>
		</ControlTemplate>
	</Setter.Value>
</Setter>

RelativeSource, TemplatedParent 통해 Binding 해보시는건 어떤가요 ?

우와… 감사합니다! 그냥 binding만 했을때는 되지 않았는데 RelativeSource도 해줘야 하는군요
