Remarks

The BindingList<T> class can be used as a base class to create a two-way data-binding mechanism. BindingList<T> provides a concrete, generic implementation of the IBindingList interface. This is an alternative to implementing the complete IBindingList interface, which can be difficult because of the subtle interaction between IBindingList, IEditableObject, and the associated CurrencyManager. However, the typical solutions programmer will use a class that provides data binding functionality, such as BindingSource, instead of directly using BindingList<T>.

BindingList<T> supports factory-created instances through the extensible AddNew method. (This same type of extensibility is also found in other classes, such as BindingSource) In addition, since this class implements the ICancelAddNew interface, it enables transactional commits or rollbacks of the new item through the EndNew and CancelNew methods.

Constructors

BindingList<T>() BindingList<T>() BindingList<T>() BindingList<T>()

Initializes a new instance of the BindingList<T> class using default values.

BindingList<T>(IList<T>) BindingList<T>(IList<T>) BindingList<T>(IList<T>) BindingList<T>(IList<T>)

Initializes a new instance of the BindingList<T> class with the specified list.
