Raises the Changing event.

Namespace:   Microsoft.VisualStudio.Shell.Design
Assembly:  Microsoft.VisualStudio.Shell.Design (in Microsoft.VisualStudio.Shell.Design.dll)

C#
C++
F#
VB
Copy 
protected:
virtual void OnChanging(
	EventArgs^ e
)

Parameters

e
Type: System::EventArgs^

An EventArgs that contains the event data.

The OnChanging method is called by the PerformChange method before it initiates a modification to the current type.

Raising an event invokes the event handler through a delegate. For more information, see NIB: Raising an Event.

The OnChanging 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 OnChanging in a derived class, be sure to call the base class’s OnChanging method so that registered delegates receive the event.
