The AllowNewChanged event's data class is EventArgs.
Handle this event to execute custom code in response to a change in the current View's AllowNew property.
A View's AllowNew state is changed in two cases:
- When the AllowNew collection does not have any elements with the value part set to false remaining.
- When the AllowNew collection, which has only items with values set to true, gets an element with the value part set to false.
To change a View's AllowNew state, use methods of the BoolList object returned by the AllowNew property.
