System.Windows.Data Namespace

Provides high-level access to the definition of a binding, which connects the properties of binding target objects (typically, WPF elements), and any data source (for example, a database, an XML file, or any object that contains data).

Defines the common characteristics of the Binding, PriorityBinding, and MultiBinding classes.

Contains information about a single instance of a Binding.

Represents the base class for BindingExpression, PriorityBindingExpression, and MultiBindingExpression.

Contains a collection of bindings and ValidationRule objects that are used to validate an object.

Represents the CollectionView for collections that implement IBindingList, such as Microsoft ActiveX Data Objects (ADO) data views.

Provides static methods to manipulate bindings, including Binding, MultiBinding, and PriorityBinding objects.

Holds an existing collection structure, such as an ObservableCollection<T> or a DataSet, to be used inside a CompositeCollection.

Provides data for the CollectionRegistering event.

Represents a view for grouping, sorting, filtering, and navigating a data collection.

Represents a group created by a CollectionView object based on the GroupDescriptions.

Provides data for the CollectionViewRegistering event.

The Extensible Application Markup Language (XAML) proxy of a CollectionView class.

Enables multiple collections and items to be displayed as a single list.

Provides a WeakEventManager implementation so that you can use the "weak event listener" pattern to attach listeners for the DataChanged event.

Common base class and contract for DataSourceProvider objects, which are factories that execute some queries to produce a single object or a list of objects that you can use as binding source objects.

Encapsulates arguments for data transfer events.

Provides information and event data that is associated with the Filter event.

Represents the collection view for collections that implement IList.

Describes a collection of Binding objects attached to a single binding target property.

Contains instance information about a single instance of a MultiBinding.

Wraps and creates an object that you can use as a binding source.

Describes a collection of Binding objects that is attached to a single binding target property, which receives its value from the first binding in the collection that produces a value successfully.

Contains instance information about a single instance of a PriorityBinding.

Describes the grouping of items using a property name as the criteria.

Implements a markup extension that describes the location of the binding source relative to the position of the binding target.

Represents an attribute that allows the author of a value converter to specify the data types involved in the implementation of the converter.

The exception that is thrown by the GetValue(Object, String) method when the value is not available.

Enables declarative access to XML data for data binding.

Declares a mapping between a uniform resource identifier (URI) and a prefix.

Represents a collection of XmlNamespaceMapping objects.

Provides a way to apply custom logic in a MultiBinding.

Provides a way to apply custom logic to a binding.

Describes the direction of the data flow in a binding.

Describes the status of a binding.

Describes the location of the binding source relative to the position of the binding target.

Describes the timing of binding source updates.

Represent the method that synchronizes a collection for cross-thread access.

Represents the method that will handle the Filter event.

Represents a method that is used to provide custom logic to select the GroupDescription based on the parent group and its level.

Represents the method that handles exceptions that are thrown during the update of the binding source value. This must be used with the ExceptionValidationRule.
