NETHostCtrl.HostEvents Property (EXNETHost)

By default, the HostEvents property is empty, which indicates that all events of the hosting event are fired through the NETHost's HostEvent event. The HostEvent event notifies your application once the hosting control ( Host ) fires an event. The HostEvents property of the NETHost control specifies the list of events that the control should handle. The AsString property of the NETHostEvent object gives a brief description of the event that occurred including the event's name, identifier and its list of arguments. Each control that the NETHost host provides its own events, so for what events the hosting control supports consult its documentation.

Use the following properties to identify/filter the event:

Name, Indicates the name of the event.
ID, Indicates the identifier of the event. The ID property may give different values for different versions of hosting control, so you must check for compatibility, so it is not guaranteed that the ID will be unique for any version of the hosting control.
HostEvents property specifies the list of events to be handled through the control's Event event, else all events are handled ( missing or not set ).

The following samples filter for "AfterSelect" event of a TreeView control.
