Filters the events that a component exposes through a TypeDescriptor.
public:
bool FilterEvents(System::ComponentModel::IComponent ^ component, System::Collections::IDictionary ^ events);
public bool FilterEvents (System.ComponentModel.IComponent component, System.Collections.IDictionary events);
abstract member FilterEvents : System.ComponentModel.IComponent * System.Collections.IDictionary -> bool
Public Function FilterEvents (component As IComponent, events As IDictionary) As Boolean
Parameters
- component
- IComponent
The component to filter events for.
- events
- IDictionary
A dictionary of events that can be modified.
Returns
true
if the set of filtered events is to be cached; false
if the filter service must query again.
Remarks
This method is called when a user requests a set of events for a component. The events are added to the dictionary with the event names as the keys and the corresponding EventDescriptor objects as the values. Implementers of this service can add, remove, or alter event entries in the dictionary.
Notes to Implementers
Return false
only when necessary, because repeated queries to the type descriptor filter service can decrease performance.
