Inheritance Hierarchy

System..::.Object
System..::.Attribute
System.Windows.Markup..::.XamlSetMarkupExtensionAttribute

Namespace: System.Windows.Markup
Assembly: System.Xaml (in System.Xaml.dll)

Syntax

Visual Basic

<AttributeUsageAttribute(AttributeTargets.Class, Inherited := True, AllowMultiple := False)> _
Public NotInheritable Class XamlSetMarkupExtensionAttribute _
    Inherits Attribute

[AttributeUsageAttribute(AttributeTargets.Class, Inherited = true, AllowMultiple = false)]
public sealed class XamlSetMarkupExtensionAttribute : Attribute

Visual C++

[AttributeUsageAttribute(AttributeTargets::Class, Inherited = true, AllowMultiple = false)]
public ref class XamlSetMarkupExtensionAttribute sealed : public Attribute

[<Sealed>]
[<AttributeUsageAttribute(AttributeTargets.Class, Inherited = true, AllowMultiple = false)>]
type XamlSetMarkupExtensionAttribute =  
    class
        inherit Attribute
    end

The XamlSetMarkupExtensionAttribute type exposes the following members.

Constructors

	Name	Description
	XamlSetMarkupExtensionAttribute	Initializes a new instance of the XamlSetMarkupExtensionAttribute class.

Top

Properties

	Name	Description
	TypeId	When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)
	XamlSetMarkupExtensionHandler	Gets the name of the handler to use for markup extension set operations.

Methods

	Name	Description
	Equals	Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Returns the hash code for this instance. (Inherited from Attribute.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsDefaultAttribute	When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
	Match	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Explicit Interface Implementations

	Name	Description
	_Attribute..::.GetIDsOfNames	Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
	_Attribute..::.GetTypeInfo	Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
	_Attribute..::.GetTypeInfoCount	Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
	_Attribute..::.Invoke	Provides access to properties and methods exposed by an object. (Inherited from Attribute.)

Remarks

Default implementation for a XAML object writer uses CLR reflection and this CLR attribute to determine if there is an intentional callback for markup extension usages that set values of a type or member. For example, a XamlServices load or parse, or a XamlXmlReader / XamlObjectWriter sequence, will use this attribute and invoke the named callback as part of the operation whenever writing the object node based on a markup extension usage.
