Type	Default	Description
CollectionBindingBehavior	AllowNew | AllowRemove	The CollectionBindingBehavior which specifies which operations a bound control can perform on a collection.

Available values:

Name	Description

AllowNew	Specifies that new items can be added to a collection by a bound control.
AllowRemove	Specifies that items can be removed from a collection by a bound control.

Remarks

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.
