The ElementPropertyDescriptor type exposes the following members.

Constructors

	Name	Description
	ElementPropertyDescriptor(ModelElement, DomainPropertyInfo, array<Attribute[])	Initializes a new instance of the ElementPropertyDescriptor class.
	ElementPropertyDescriptor(ElementTypeDescriptor, ModelElement, DomainPropertyInfo, array<Attribute[])	Initializes a new instance of the ElementPropertyDescriptor class and specifies a default value provider.

Properties

	Name	Description
	AttributeArray	Gets or sets an array of attributes. (Inherited from MemberDescriptor.)
	Attributes	Gets the collection of attributes for this member. (Inherited from MemberDescriptor.)
	Category	Gets the category in which to group the domain property when the property is displayed in a PropertyGrid control that is set to Categorized mode. (Overrides MemberDescriptor.Category.)
	ComponentType	Gets the type of the model element to which this property is bound. (Overrides PropertyDescriptor.ComponentType.)
	Converter	Gets the converter for the described property. (Overrides PropertyDescriptor.Converter.)
	Description	Gets the description of the described property, as specified in the DescriptionResourceAttribute. (Overrides MemberDescriptor.Description.)
	DesignTimeOnly	Gets whether this member should be set only at design time, as specified in the DesignOnlyAttribute. (Inherited from MemberDescriptor.)
	DisplayName	Gets the display name of the described property, as specified in the DisplayNameResourceAttribute. (Overrides MemberDescriptor.DisplayName.)
	DomainPropertyInfo	Gets the property information object that was used to create this property descriptor.
	IsBrowsable	Gets a value indicating whether the member is browsable, as specified in the BrowsableAttribute. (Inherited from MemberDescriptor.)
	IsInstanceBased	Test if this PropertyDescriptor is based on an instance or a static type.
	IsLocalizable	Gets a value indicating whether this property should be localized, as specified in the LocalizableAttribute. (Inherited from PropertyDescriptor.)
	IsReadOnly	Gets a value that indicates whether the described property is read-only. (Overrides PropertyDescriptor.IsReadOnly.)
	ModelElement	Gets the model element that was used to create this property descriptor.
	Name	Gets the name of the member. (Inherited from MemberDescriptor.)
	NameHashCode	Gets the hash code for the name of the member, as specified in GetHashCode. (Inherited from MemberDescriptor.)
	PropertyType	Gets the property type of the described property. (Overrides PropertyDescriptor.PropertyType.)
	SerializationVisibility	Gets a value indicating whether this property should be serialized, as specified in the DesignerSerializationVisibilityAttribute. (Inherited from PropertyDescriptor.)
	SupportsChangeEvents	Gets a value indicating whether value change notifications for this property may originate from outside the property descriptor. (Inherited from PropertyDescriptor.)

Methods

	Name	Description
	AddValueChanged	(Overrides PropertyDescriptor.AddValueChanged(Object, EventHandler).)
	CanResetValue	Indicates whether the value of the domain property can be reset. (Overrides PropertyDescriptor.CanResetValue(Object).)
	CanSetProperty
	CreateAttributeCollection	Creates a collection of attributes using the array of attributes passed to the constructor. (Inherited from MemberDescriptor.)
	CreateInstance	Creates an instance of the specified type. (Inherited from PropertyDescriptor.)
	Equals	Compares this to another object to see if they are equivalent. (Inherited from PropertyDescriptor.)
	FillAttributes	Adds the attributes of the PropertyDescriptor to the specified list of attributes in the parent class. (Inherited from PropertyDescriptor.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetChildProperties()	Returns the default PropertyDescriptorCollection. (Inherited from PropertyDescriptor.)
	GetChildProperties(array<Attribute[])	Returns a PropertyDescriptorCollection using a specified array of attributes as a filter. (Inherited from PropertyDescriptor.)
	GetChildProperties(Object)	Returns a PropertyDescriptorCollection for a given object. (Inherited from PropertyDescriptor.)
	GetChildProperties(Object, array<Attribute[])	Returns a PropertyDescriptorCollection for a given object using a specified array of attributes as a filter. (Inherited from PropertyDescriptor.)
	GetEditor	Returns a value editor for the described property. (Overrides PropertyDescriptor.GetEditor(Type).)
	GetElementPropertyDescriptor	Gets the ElementPropertyDescriptor given a ModelElement and DomainPropertyInfo.
	GetHashCode	Returns the hash code for this object. (Inherited from PropertyDescriptor.)
	GetInvocationTarget	This method returns the object that should be used during invocation of members. (Inherited from PropertyDescriptor.)
	GetSetValueTransactionName	Returns a localized string for the name of the set value transaction.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetTypeFromName	Returns a type using its name. (Inherited from PropertyDescriptor.)
	GetValue	Gets the value of the domain property. (Overrides PropertyDescriptor.GetValue(Object).)
	GetValueChangedHandler	Retrieves the current set of ValueChanged event handlers for a specific component (Inherited from PropertyDescriptor.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnValueChanged	Raises the ValueChanged event that you implemented. (Inherited from PropertyDescriptor.)
	RemoveValueChanged	(Overrides PropertyDescriptor.RemoveValueChanged(Object, EventHandler).)
	ResetValue	Resets the value of the domain property. (Overrides PropertyDescriptor.ResetValue(Object).)
	SetProperty	Set the property value. Property value is generally set via an ElementPropertyDescriptor. It will be set directly via the SetValue method on propertyInfo if - IsBrowsable attribute is set to false on propertyInfo and ElementPropertyDescriptor is not found.
	SetValue	Sets the value of the domain property. (Overrides PropertyDescriptor.SetValue(Object, Object).)
	ShouldSerializeValue	Indicates whether the value of the domain property should be serialized. (Overrides PropertyDescriptor.ShouldSerializeValue(Object).)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

This class provides dynamic custom property information for a domain property of a model element.

The Domain-Specific Language Tools (DSL Tools) use this type to represent the domain class properties in a domain model. This type controls how a property is handled by the property grid in the domain model and provides transactions for modifying the described property.

To create a customized element property descriptor, inherit from this class and override one or more of the members.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
