Public Event ListChanged As ListChangedEventHandler
The ListChanged event's data class is ListChangedEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| ListChangedType | Gets the type of change. |
| NewIndex | Gets the index of the item affected by the change. |
| OldIndex | Gets the old index of an item that has been moved. |
| PropertyDescriptor | Gets the PropertyDescriptor that was added, changed, or deleted. |
The ListChanged event is raised as a result of adding, inserting or removing records from the editor’s data source specified by the RepositoryItemLookUpEditBase.DataSource property. The editor subscribes the ListChanged event and updates itself as needed.
The editor’s ListChanged event is equivalent to the RepositoryItemLookUpEdit.ListChanged event available via the BaseEdit.Properties object, i.e. adding/removing an event handler for the current event actually affects the RepositoryItemLookUpEdit.ListChanged event.
