Syntax

C++

[AttributeUsageAttribute(AttributeTargets::Assembly, AllowMultiple = true)]
public ref class TagPrefixAttribute sealed : Attribute

Constructors

	Name	Description
	TagPrefixAttribute(String^, String^)	Initializes a new instance of the TagPrefixAttribute class.

Properties

	Name	Description
	NamespaceName	Gets the namespace prefix for the specified control.
	TagPrefix	Gets the tag prefix for the specified control.
	TypeId	When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)

Methods

	Name	Description
	Equals(Object^)	This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)
	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(Object^)	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)
	ToString()	Returns a string that represents the current object.(Inherited from Object.)

Explicit Interface Implementations

	Name	Description
	_Attribute::GetIDsOfNames(Guid%, IntPtr, UInt32, UInt32, IntPtr)	Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)
	_Attribute::GetTypeInfo(UInt32, UInt32, IntPtr)	Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)
	_Attribute::GetTypeInfoCount(UInt32%)	Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)
	_Attribute::Invoke(UInt32, Guid%, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)	Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

The TagPrefixAttribute class defines an assembly-level attribute needed to specify tag prefix aliases for custom controls. This attribute is used by tools such as Microsoft Visual Studio to automatically generate a Register directive in the ASP.NET page where the custom controls are used.

This directive registers the tag prefix with a namespace. Moreover, it specifies the assembly where the custom control code implementation resides. With this directive in place, you can use custom controls in a Web page declaratively.
