DependencyPropertyDescriptor Class

Provides an extension of PropertyDescriptor that accounts for the additional property characteristics of a dependency property.

Namespace:  System.ComponentModel
Assembly:  WindowsBase (in WindowsBase.dll)

public sealed class DependencyPropertyDescriptor : PropertyDescriptor

The DependencyPropertyDescriptor type exposes the following members.

  NameDescription
Protected propertyAttributeArrayGets or sets an array of attributes. (Inherited from MemberDescriptor.)
Public propertyAttributesGets the collection of attributes for this member. (Overrides MemberDescriptor.Attributes.)
Public propertyCategoryGets the name of the category that the member belongs to, as specified in the CategoryAttribute. (Overrides MemberDescriptor.Category.)
Public propertyComponentTypeGets the type of the component this property is bound to. (Overrides PropertyDescriptor.ComponentType.)
Public propertyConverterGets the type converter for this property. (Overrides PropertyDescriptor.Converter.)
Public propertyDependencyPropertyReturns the dependency property identifier.
Public propertyDescriptionGets the description of the member, as specified in the DescriptionAttribute. (Overrides MemberDescriptor.Description.)
Public propertyDesignerCoerceValueCallbackGets or sets a callback that designers use to modify the effective value of a dependency property before the dependency property value is stored in the dependency property engine.
Public propertyDesignTimeOnlyGets whether this member should be set only at design time, as specified in the DesignOnlyAttribute. (Overrides MemberDescriptor.DesignTimeOnly.)
Public propertyDisplayNameGets the name that can be displayed in a window, such as a Properties window. (Overrides MemberDescriptor.DisplayName.)
Public propertyIsAttachedGets a value that indicates whether the property is registered as an attached property and is being used through an attached usage.
Public propertyIsBrowsableGets a value that indicates the value of the BrowsableAttribute on the property. (Overrides MemberDescriptor.IsBrowsable.)
Public propertyIsLocalizableGets a value indicating whether this property should be localized, as specified in the LocalizableAttribute. (Overrides PropertyDescriptor.IsLocalizable.)
Public propertyIsReadOnlyGets a value indicating whether this property is read-only. (Overrides PropertyDescriptor.IsReadOnly.)
Public propertyMetadataGets the metadata associated with the dependency property.
Public propertyNameGets the name of the member. (Inherited from MemberDescriptor.)
Protected propertyNameHashCodeGets the hash code for the name of the member, as specified in GetHashCode. (Inherited from MemberDescriptor.)
Public propertyPropertyTypeGets the represented Type of the dependency property. (Overrides PropertyDescriptor.PropertyType.)
Public propertySerializationVisibilityGets a value indicating whether this property should be serialized, as specified in the DesignerSerializationVisibilityAttribute. (Inherited from PropertyDescriptor.)
Public propertySupportsChangeEventsIndicates whether value change notifications for this property may originate from outside the property descriptor, such as from the component itself, or whether notifications will only originate from direct calls made to SetValue. (Overrides PropertyDescriptor.SupportsChangeEvents.)

  NameDescription
Public methodAddValueChangedEnables other objects to be notified when this property changes. (Overrides PropertyDescriptor.AddValueChanged(Object, EventHandler).)
Public methodCanResetValueReturns whether resetting an object changes its value. (Overrides PropertyDescriptor.CanResetValue(Object).)
Protected methodCreateAttributeCollectionCreates a collection of attributes using the array of attributes passed to the constructor. (Inherited from MemberDescriptor.)

Public methodEqualsCompares two DependencyPropertyDescriptor instances for equality. (Overrides PropertyDescriptor.Equals(Object).)
Protected methodFillAttributesAdds the attributes of the PropertyDescriptor to the specified list of attributes in the parent class. (Inherited from PropertyDescriptor.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodStatic memberFromName(String, Type, Type)Returns a DependencyPropertyDescriptor for a provided property name.
Public methodStatic memberFromName(String, Type, Type, Boolean)Returns a DependencyPropertyDescriptor for a provided property name.
Public methodStatic memberFromProperty(PropertyDescriptor)Returns a DependencyPropertyDescriptor for a provided PropertyDescriptor.
Public methodStatic memberFromProperty(DependencyProperty, Type)Returns a DependencyPropertyDescriptor for a provided dependency property and target type.

Protected methodGetTypeFromNameReturns a type using its name. (Inherited from PropertyDescriptor.)
Public methodGetValueResturns the current value of the property on a component. (Overrides PropertyDescriptor.GetValue(Object).)
Protected methodGetValueChangedHandlerRetrieves the current set of ValueChanged event handlers for a specific component (Inherited from PropertyDescriptor.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Protected methodOnValueChangedRaises the ValueChanged event that you implemented. (Inherited from PropertyDescriptor.)
Public methodRemoveValueChangedEnables other objects to be notified when this property changes. (Overrides PropertyDescriptor.RemoveValueChanged(Object, EventHandler).)
Public methodResetValueResets the value for this property of the component to the default value. (Overrides PropertyDescriptor.ResetValue(Object).)
Public methodSetValueSets the value of the component to a different value. (Overrides PropertyDescriptor.SetValue(Object, Object).)
Public methodShouldSerializeValueIndicates whether the value of this property needs to be persisted by serialization processes. (Overrides PropertyDescriptor.ShouldSerializeValue(Object).)
Public methodToStringConverts the value of this instance to its equivalent string representation. (Overrides Object.ToString().)

This class is primarily used by designer applications. These applications may need to report the dependency property characteristics through property windows or other tools used for editing property values.

In order to check a specific property to determine whether it has DependencyPropertyDescriptor available to serve as a PropertyDescriptor, call either DependencyPropertyDescriptor.FromProperty(PropertyDescriptor), or DependencyPropertyDescriptor.FromName. If either method returns null, then the property is not a dependency property. If the method returns a valid DependencyPropertyDescriptor , then the property is a dependency property.
