Properties

	Name	Description
	AttachedOwnerType	When overridden in a derived class, gets the type which defines this property.
	Collection	When overridden in a derived class, gets the Value property cast as a ModelItemCollection.
	ComputedValue	When overridden in a derived class, gets the currently computed value for this property.
	DefaultValue	When overridden in a derived class, gets the default value for this property.
	Dictionary	When overridden in a derived class, gets the Value property cast as a ModelItemDictionary.
	IsAttached	When overridden in a derived class, gets a value indicating whether the property represents an attached property from a different type.
	IsBrowsable	When overridden in a derived class, gets a value indicating whether the property can be shown in a property window.
	IsCollection	When overridden in a derived class, gets a value indicating whether the value contained in the property is an ItemCollection.
	IsDictionary	When overridden in a derived class, gets a value indicating whether the value contained in the property is an ItemDictionary.
	IsReadOnly	When overridden in a derived class, gets a value indicating whether the property is read-only.
	IsSet	When overridden in a derived class, gets a value indicating whether the property's value is set locally.
	Name	When overridden in a derived class, gets the name of this property.
	Parent	When overridden in a derived class, gets the parent of this property.
	PropertyType	When overridden in a derived class, gets the data type of the property.
	Value	When overridden in a derived class, gets the value of this property.

Methods

	Name	Description
	ClearValue	When overridden in a derived class, clears the local value for the property.
	Equals	Determines whether the specified object is equal to this ModelProperty object. (Overrides Object.Equals(Object).)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetAttributes(Type)	Gets the attributes of the requested type that are declared on this property and the property's property type.
	GetAttributes(TypeIdentifier)	Gets the attributes of the requested type that are declared on this property and the property's property type.
	GetHashCode	Serves as a hash function for a particular type. (Overrides Object.GetHashCode().)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsPropertyOfType(Type)	Gets a value that indicates whether this property is of the specified type or implements the specified interface.
	IsPropertyOfType(TypeIdentifier)	Gets a value that indicates whether this property is of the specified type or implements the specified interface.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	SetValue	When overridden in a derived class, sets a local value on a property.
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Operators

	Name	Description
	Equality	Determines whether two specified ModelProperty objects are equal.
	Inequality	Determines whether two specified ModelProperty objects are not equal.

Remarks

A ModelProperty represents a property on an item. ModelProperty objects are associated with an instance of an item, which enables them to have simple Value get/set properties, instead of the more cumbersome GetValue/SetValue mechanism of PropertyDescriptor. A ModelProperty’s value may come from a locally set value, or it may be inherited from somewhere higher up in the property mechanism. Because all items in the tree contain Source properties, you can easily determine the real source of a property value by using the following code:

Console.WriteLine(property.Value.Source); 

Value returns nulla null reference (Nothing in Visual Basic) if the property is not set anywhere in the hierarchy. Type converters and editors defined on the underlying data model are wrapped so that they accept ModelItem objects as parameters.

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.
