System. Windows .Forms (system. windows .forms.dll)

class

This class represents a bag of BindingManagerBase objects for a set of data bound controls. You can retrieve the BindingContext for a Control using the Control.BindingContext member. You can retrieve the binding manager for a particular child control using Item (this is the indexer property).

The BindingContext class Add() and Remove() methods , which allow you to add (or remove) a new binding manager for a data source, are actually protected. To create additional binding managers for a container BindingContext , you create a new BindingContext object and assign it to the Control.BindingContext of your child control(s). This has the effect of creating a new binding manager in the parent's BindingContext .

See Binding for more information about the data-binding hierarchy.
