ParameterCollection.ParametersChanged Event

Occurs when one or more Parameter objects contained by the collection changes state.
public:
event EventHandler ^ ParametersChanged;public event EventHandler ParametersChanged;member this.ParametersChanged : EventHandler Public Custom Event ParametersChanged As EventHandler Event Type
Remarks
If the ParameterCollection collection is contained by a data source control, the ParametersChanged event raises the data source control's DataSourceChanged event, causing any data-bound controls to rebind.
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnParameterChanged method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors
When overriding OnParameterChanged() in a derived class, be sure to call the base class's OnParameterChanged() method so that registered delegates receive the event.
