BindingSource Component

.NET Framework 4.5

Encapsulates a data source for binding to controls.

The BindingSource component serves two purposes. First, it provides a layer of indirection when binding the controls on a form to data. This is accomplished by binding the BindingSource component to your data source, and then binding the controls on your form to the BindingSource component. All further interaction with the data, including navigating, sorting, filtering, and updating, is accomplished with calls to the BindingSource component.

Second, the BindingSource component can act as a strongly typed data source. Adding a type to the BindingSource component with the Add method creates a list of that type.
