ParameterCollection::ParametersChanged Event

Occurs when one or more Parameter objects contained by the collection changes state.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

public:
 event EventHandler^ ParametersChanged {
	void add (EventHandler^ value);
	void remove (EventHandler^ value);
}

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 Raising an Event.

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.
