Nasıl Yapılır: İliştirilmiş Özelliği Kaydet
This example shows how to register an attached property and provide public accessors so that you can use the property in both Extensible Application Markup Language (XAML) and code. Attached properties are a syntax concept defined by Extensible Application Markup Language (XAML). Most attached properties for WPF types are also implemented as dependency properties. You can use dependency properties on any DependencyObject types.
Örnek
The following example shows how to register an attached property as a dependency property, by using the RegisterAttached method. The provider class has the option of providing default metadata for the property that is applicable when the property is used on another class, unless that class overrides the metadata. In this example, the default value of the IsBubbleSource property is set to false.
Statik get ve adlandırma kuralını izlemeniz set erişimcileri (bağımlılık özelliği kayıt edilmemiş olsa bile) iliştirilmiş bir özellik için bir sağlayıcı sınıfı vermesi gereken Set[AttachedPropertyName] ve Get[AttachedPropertyName]. Bu erişimcileri gerekli şekilde hareket XAML okuyucu özellik bir öznitelik olarak algılayabilir XAML ve uygun türleri.
Public Shared ReadOnly IsBubbleSourceProperty As DependencyProperty = DependencyProperty.RegisterAttached("IsBubbleSource", GetType(Boolean), GetType(AquariumObject), New FrameworkPropertyMetadata(False, FrameworkPropertyMetadataOptions.AffectsRender))
Public Shared Sub SetIsBubbleSource(ByVal element As UIElement, ByVal value As Boolean)
element.SetValue(IsBubbleSourceProperty, value)
End Sub
Public Shared Function GetIsBubbleSource(ByVal element As UIElement) As Boolean
Return CType(element.GetValue(IsBubbleSourceProperty), Boolean)
End Function
public static readonly DependencyProperty IsBubbleSourceProperty = DependencyProperty.RegisterAttached(
"IsBubbleSource",
typeof(Boolean),
typeof(AquariumObject),
new FrameworkPropertyMetadata(false, FrameworkPropertyMetadataOptions.AffectsRender)
);
public static void SetIsBubbleSource(UIElement element, Boolean value)
{
element.SetValue(IsBubbleSourceProperty, value);
}
public static Boolean GetIsBubbleSource(UIElement element)
{
return (Boolean)element.GetValue(IsBubbleSourceProperty);
}
