Defines an attribute applied to properties that contain ID references. This class cannot be inherited.
Assembly: System.Web (in System.Web.dll)
Thetype exposes the following members.
|Equals||Returns a value that indicates whether this instance is equal to a specified object. (Overrides Attribute::Equals(Object).)|
|GetHashCode||Returns the hash code for this instance. (Overrides Attribute::GetHashCode().)|
|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.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
|_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.)|
The class is applied to properties that contain ID references. ContentPlaceHolderID is an example of a property that contains an ID reference. When this attribute is applied, designers can provide additional functionality during design time, such as listing IDs.
The following code example demonstrates how the attribute is applied to a property that evaluates to a string. In this example, the DataSourceID member identifies a data source control and therefore specifies the DataSourceControl type.
