.NetGrid v2.9.2 has been released.

A significant increase in productivity when working with objects that implement the INotifyPropertyChanged interface The following bug has been fixed: [BUG] Fixed a bug where the grid redraw the content of the entire row upon receiving notification from INotifyPropertyChanged interface for missing or hidden column. [BUG] Fixed minor bugs in the designer.

Why BindingList is slow with objects implementing INotifyPropertyChanged interface

A BindingList<T> is the main tool for binding objects to grids. It is a container that may notify subscribers when data is added or removed. For this purpose it provides public ListChanged event that specifies collection changes with ListChangedType. Besides changing the collection itself (adding, removing, etc) the binding list notifies of data object changes. [...]

Binding list and thread safety

Data binding is the basis of modern applications based on separation of data layer from presentation layer. The main purpose of such separation is to make application logic independent of its representation. Otherwise, logic code should not directly call presentation layer class methods (i.e. Control class methods). When internal state changes, business logic layer sends [...]

Declarative data binding

Component model has two basic interfaces that are broadly used in data binding: INotifyPropertyChanged and IBindingList. The first interface notifies subscribers of bound object modifications while the second one notifies of object collection modifications. Object collections usually don’t contain hierarchy information and they are not intended for this purpose. Different grid developers use different ways [...]
