Namespace: System.ComponentModel

The System.ComponentModel namespace provides classes that are used to implement the run-time and design-time behavior of components and controls. This namespace includes the base classes and interfaces for implementing attributes and type converters, binding to data sources, and licensing components.

The classes in this namespace divide into the following categories:

Core component classes. See the Component, IComponent, Container, and IContainer classes.
Component licensing. See the License, LicenseManager, LicenseProvider, and LicenseProviderAttribute classes.
Attributes. See the Attribute class.
Descriptors and persistence. See the TypeDescriptor, EventDescriptor, and PropertyDescriptor classes.
Type converters. See the TypeConverter class.

Members of System.ComponentModel Namespace

Classes

Class	Description
class CancelEventArgs	Provides data for a cancelable event.
class CollectionChangeEventArgs	Provides data for the DataColumnCollection.CollectionChanged event.
class Component	Provides the base implementation for the IComponent interface and enables object-sharing between applications.
class ComponentCollection	Specifies a collection of Component objects in the Container.
class Container	Encapsulates zero or more components.
class DefaultValueAttribute	Specifies the default value for a property.
class EventHandlerList	Provides a simple list of delegates. This class cannot be inherited.
class InvalidEnumArgumentException	The exception thrown when using invalid arguments that are enumerators.
class MarshalByValueComponent	Implements IComponent and provides the base implementation for remotable components that are marshaled by value (a copy of the serialized object is passed).
class PropertyChangedEventArgs	Provides data for the event.
class WarningException	Specifies an exception that is handled as a warning instead of an error.
class Win32Exception	The exception that is thrown for a Win32 error code.

Interfaces

Interface	Description
interface IComponent	Provides functionality required by all components. Component is the default implementation of IComponent and serves as the base class for all components in the common language runtime.
interface IContainer	Provides functionality for containers. Containers are objects that logically contain zero or more components.
interface IEditableObject	Provides functionality to commit or rollback changes to an object that is used as a data source.
interface ISite	Provides functionality required by sites.
interface ISupportInitialize	Specifies that this object supports a simple, transacted notification for batch initialization.
interface ISynchronizeInvoke	Provides a way to synchronously or asynchronously execute a delegate.

Delegates

Delegate	Description
delegate CancelEventHandler	Represents the method that handles a cancellable event.
delegate CollectionChangeEventHandler	Represents the method that handles the DataColumnCollection.CollectionChanged event raised when adding elements to or removing elements from a collection.
delegate PropertyChangedEventHandler	Represents the method that will handle the event raised when a property is changed on a component.
