System.ComponentModel namespaces

System.ComponentModel, System.ComponentModel.DataAnnotations, and System.ComponentModel.DataAnnotations.Schema contain types that implement the run-time and design-time behavior of components and controls.

This topic displays the types in the System.ComponentModel namespaces that are included in the .NET for Windows Store apps. Note that the .NET for Windows Store apps does not include all the members of each type. For information about individual types, see the linked topics. The documentation for a type indicates which members are included in the .NET for Windows Store apps.

System.ComponentModel namespace

Types supported in the .NET for Windows Store apps	Description
AsyncCompletedEventArgs	Provides data for the MethodNameCompleted event.
AsyncCompletedEventHandler	Represents the method that will handle the MethodNameCompleted event of an asynchronous operation.
CancelEventArgs	Provides data for a cancelable event.
DataErrorsChangedEventArgs	Provides data for the INotifyDataErrorInfo.ErrorsChanged event.
DefaultValueAttribute	Specifies the default value for a property.
EditorBrowsableAttribute	Specifies that a property or method is viewable in an editor. This class cannot be inherited.
EditorBrowsableState	Specifies the browsable state of a property or method from within an editor.
IChangeTracking	Defines the mechanism for querying the object for changes and resetting of the changed status.
IEditableObject	Provides functionality to commit or roll back changes to an object that is used as a data source.
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.
IRevertibleChangeTracking	Provides support for rolling back the changes
ProgressChangedEventArgs	Provides data for the ProgressChanged event.
ProgressChangedEventHandler	Represents the method that will handle the ProgressChanged event of the BackgroundWorker class. This class cannot be inherited.
PropertyChangedEventArgs	Provides data for the PropertyChanged event.
PropertyChangedEventHandler	Represents the method that will handle the PropertyChanged event raised when a property is changed on a component.

System.ComponentModel.DataAnnotations namespace

Types supported in the .NET for Windows Store apps	Description
AssociationAttribute	Specifies that an entity member represents a data relationship, such as a foreign key relationship.
ConcurrencyCheckAttribute	Specifies that a property participates in optimistic concurrency checks.
CustomValidationAttribute	Specifies a custom validation method that is used to validate a property or class instance.
DataType	Represents an enumeration of the data types associated with data fields and parameters.
DataTypeAttribute	Specifies the name of an additional type to associate with a data field.
DisplayAttribute	Provides a general-purpose attribute that lets you specify localizable strings for types and members of entity partial classes.
DisplayColumnAttribute	Specifies the column that is displayed in the referred table as a foreign-key column.
DisplayFormatAttribute	Specifies how data fields are displayed and formatted.
EditableAttribute	Indicates whether a data field is editable.
EnumDataTypeAttribute	Enables a .NET Framework enumeration to be mapped to a data column.
FilterUIHintAttribute	Represents an attribute that is used to specify the filtering behavior for a column.
KeyAttribute	Denotes one or more properties that uniquely identify an entity.
RangeAttribute	Specifies the numeric range constraints for the value of a data field.
RegularExpressionAttribute	Specifies that a data field value must match the specified regular expression.
RequiredAttribute	Specifies that a data field value is required.
StringLengthAttribute	Specifies the minimum and maximum length of characters that are allowed in a data field.
TimestampAttribute	Specifies the data type of the column as a row version.
UIHintAttribute	Specifies the template or user control used to display a data field.
ValidationAttribute	Serves as the base class for all validation attributes.
ValidationContext	Describes the context in which a validation check is performed.
ValidationException	Represents the exception that occurs during validation of a data field when the ValidationAttribute class is used.
ValidationResult	Represents a container for the results of a validation request.
Validator	Defines a helper class that can be used to validate objects, properties, and methods when it is included in their associated ValidationAttribute attributes.

System.ComponentModel.DataAnnotations.Schema namespace

Types supported in the .NET for Windows Store apps
DatabaseGeneratedAttribute	Represents a database generated attribute.
DatabaseGeneratedOption	Enumerates a database generated options.
