Связывание кода в WPF

Question

Как добавить привязку в код позади?

<Canvas.Effect > 
     <fx:GreenscreenEffect Tolerance="{Binding Value, ElementName=sliderGreenscreenTolerance}" 
          ColorR="{Binding Value, ElementName=sliderGreenscreenR}" 
          ColorG="{Binding Value, ElementName=sliderGreenscreenG}" 
          ColorB="{Binding Value, ElementName=sliderGreenscreenB}" /> 
</Canvas.Effect> 

Я пытался без успеха:

GreenscreenEffect effect = new GreenscreenEffect() ; 
Binding binding = new Binding(); 
binding.Path = new PropertyPath("Tolerance"); 
binding.Source = sliderGreenscreenTolerance.Value; 
BindingOperations.SetBinding(effect, TextBlock.TextProperty, binding); 
// etc. for each property 

Answer 1

GreenscreenEffect effect = new GreenscreenEffect() ; 
Binding binding = new Binding(); 
binding.Path = new PropertyPath("Value"); 
binding.Source = sliderGreenscreenTolerance; 
// effect.SetBinding(GreenscreenEffect.ToleranceProperty, binding); 
// Commented above out since GreenscreenEffect is not a FrameworkElement, thus: 
BindingOperations.SetBinding(effect, GreenscreenEffect.ToleranceProperty, binding); 
// ... ColorRProperty etc... 

Answer 2

Я нашел решение:

GreenscreenEffect effect = new GreenscreenEffect() ; 
       Binding binding = new Binding(); 
       binding.Path = new PropertyPath("Value"); 
       binding.Source = sliderGreenscreenTolerance; 
       BindingOperations.SetBinding(effect, GreenscreenEffect.ToleranceProperty, binding);
