Syntax

protected virtual void OnNewItemNeeded(
    EventArgs e
)

protected:
virtual void OnNewItemNeeded(
    EventArgs^ e
)

abstract OnNewItemNeeded : 
        e:EventArgs -> unit
override OnNewItemNeeded : 
        e:EventArgs -> unit

Protected Overridable Sub OnNewItemNeeded (
    e As EventArgs
)

Parameters

• e
  Type: System.EventArgs

  An object that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnNewItemNeeded method also enables 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 you override OnNewItemNeeded in a derived class, make sure to call the OnNewItemNeeded method of the base class so that registered delegates receive the event.
