Data List Policies

Data List policies provide places where you can hook in behaviors that trigger when items within a data list are operated upon. When items are added to a data list, removed from a data list or updated, these policies trigger and may fire into your custom handlers.

The following policies are available:

Policy QName	Description
p:beforeAddListItem	Raised before an item is added to a list
p:afterAddListItem	Raised after an item is added to a list
p:beforeUpdateListItem	Raised before an item within a list is updated
p:afterUpdateListItem	Raised after an item within a list is updated
p:beforeRemoveListItem	Raised before an item is removed from a list
p:afterRemoveListItem	Raised after an item is removed from a list
