The following properties accept/return CollectionBindingBehavior values:

• XPBaseCollection.BindingBehavior
• XPBindingSource.BindingBehavior

Remarks

A collection in XPO (the XPBaseCollection class descendant) implements the IBindingList interface, so it can be bound to a visual control (for instance, the XtraGrid). The control will interact with the XPCollection via this interface. Use the collection’s XPBaseCollection.BindingBehavior property of the CollectionBindingBehavior class to specify which operations on the collection are enabled for the bound control.

The XPBaseCollection.BindingBehavior property’s value determines the return values of the collection’s AllowNew and AllowRemove properties.
