System.ComponentModel Namespace
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
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, and for performing asynchronous operations.
| Class | Description | |
|---|---|---|
![]() | AlternateContentPropertyAttribute | Indicates whether a non-content property should be displayed in the the object tree. |
![]() | AsyncCompletedEventArgs | Provides data for the MethodNameCompleted event. |
![]() | AsyncOperation | Tracks the lifetime of an asynchronous operation. |
![]() | AsyncOperationManager | Provides concurrency management for classes that support asynchronous method calls. This class cannot be inherited. |
![]() | BackgroundWorker | Runs an operation on a separate thread. |
![]() | BrowsableAttribute | Specifies whether a property or event should be displayed in a Properties window. |
![]() | CancelEventArgs | Provides data for a cancelable event. |
![]() | CategoryAttribute | Specifies the name of the category in which to group the property or event when displayed in a property grid control set to Categorized mode. |
![]() | ComponentCollection | Gets a specific component in the container. |
![]() | CurrentChangingEventArgs | Provides data for the ICollectionView.CurrentChanging event. |
![]() | DataErrorsChangedEventArgs | Provides data for the INotifyDataErrorInfo.ErrorsChanged event. |
![]() | DefaultValueAttribute | Specifies the default value for a property. |
![]() | DescriptionAttribute | Specifies a description for a property or event. |
![]() | DesignerProperties | Provides attached properties that can be used to communicate with a designer. |
![]() | DoWorkEventArgs | Provides data for the DoWork event. |
![]() | EditorBrowsableAttribute | Specifies that a property or method is viewable in an editor. This class cannot be inherited. |
![]() | GroupDescription | Provides a base class for defining how to divide the items in a collection into groups. |
![]() | ProgressChangedEventArgs | Provides data for the ProgressChanged event. |
![]() | PropertyChangedEventArgs | Provides data for the PropertyChanged event. |
![]() | PropertyChangingEventArgs | Provides data for the INotifyPropertyChanging.PropertyChanging event. |
![]() | PropertyDescriptor | Provides a description of a property. |
![]() | ReadOnlyAttribute | Specifies whether the property this attribute is applied to is read-only or read/write. |
![]() | RunWorkerCompletedEventArgs | Provides data for the RunWorkerCompleted event. |
![]() | SortDescriptionCollection | Represents a collection of SortDescription instances. |
![]() | TypeConverter | Provides a unified way of converting types of values to other types. TypeConverter typically supports string-to-object conversion, either for property editors in design environments, or to enable XAML usages. |
![]() | TypeConverterAttribute | Specifies the class to use as a type converter for the type or property that this attribute is bound to. |
| Structure | Description | |
|---|---|---|
![]() | SortDescription | Defines the direction and the property name that will be used as the criteria for sorting a collection. |
| Interface | Description | |
|---|---|---|
![]() | IChangeTracking | Defines the mechanism for querying the object for changes and resetting of the changed status. |
![]() | ICollectionView | Enables collections to have the functionalities of current record management, custom sorting, filtering, and grouping. |
![]() | ICollectionViewFactory | Defines a method that enables a collection to provide a custom view for specialized sorting, filtering, grouping, and currency. |
![]() | IComponent | When implemented by a class, gets or sets the ISite associated with the component. |
![]() | IContainer | Provides functionality for containers. Containers are objects that logically contain zero or more components. |
![]() | IDataErrorInfo | Defines members that data entity classes can implement to provide custom validation support. |
![]() | IEditableCollectionView | Defines methods and properties that a collection view implements to provide editing capabilities to a collection. |
![]() | IEditableObject | Represents an object that has an editing mode and the ability to commit or revert changes. |
![]() | INotifyDataErrorInfo | Defines members that data entity classes can implement to provide custom synchronous and asynchronous validation support. |
![]() | INotifyPropertyChanged | Notifies clients that a property value has changed. |
![]() | INotifyPropertyChanging | Defines an event for notifying clients that a property value is changing. |
![]() | IRevertibleChangeTracking | Provides support for rolling back changes. |
![]() | ISite | Provides functionality required by sites. Sites bind a component to a container and enable communication between them, as well as provide a way for the container to manage its components. |
![]() | ISupportInitialize | Specifies that this object supports a simple, transacted notification for batch initialization. |
![]() | ITypeDescriptorContext | Provides information about a context to a type converter or a value editor, so that the type converter or editor can perform a conversion. |
| Delegate | Description | |
|---|---|---|
![]() | AsyncCompletedEventHandler | Represents the method that will handle the MethodNameCompleted event of an asynchronous operation. |
![]() | CurrentChangingEventHandler | Represents a method that can handle the CurrentChanging event of an ICollectionView implementation. |
![]() | DoWorkEventHandler | Represents the method that will handle the DoWork event that is raised when the RunWorkerAsync method is called. |
![]() | ProgressChangedEventHandler | Represents the method that will handle the ProgressChanged event that is raised when progress is reported by a BackgroundWorker. |
![]() | PropertyChangedEventHandler | Represents the method that will handle the INotifyPropertyChanged.PropertyChanged event. |
![]() | PropertyChangingEventHandler | Represents a method that will handle the INotifyPropertyChanging.PropertyChanging event. |
![]() | RunWorkerCompletedEventHandler | Represents the method that will handle the RunWorkerCompleted event that is raised when the operation performed by a BackgroundWorker has completed, has been canceled, or has raised an exception. |
| Enumeration | Description | |
|---|---|---|
![]() | EditorBrowsableState | Specifies the browsable state of a property or method from within an editor. |
![]() | ListSortDirection | Specifies the direction of a sort operation. |
![]() | NewItemPlaceholderPosition | Specifies where the placeholder for a new item appears in an IEditableCollectionView. |
