The XPBaseCollection class implements the IBindingList interface, so an XPCollection object can be bound to a visual control (for instance, the XtraGrid). The control will interact with the XPCollection via this interface. The BindingBehavior property determines which operations a bound control can perform on the collection (whether adding new and/or removing existing items is allowed for the bound control). Regardless of the BindingBehavior property’s value the collection’s contents can still be modified by calling the collection’s appropriate methods.
The following code snippet (auto-collected from DevExpress Examples) contains a reference to the BindingBehavior property.
