System.Windows.Forms.BindingsCollection.OnCollectionChanging Method

Raises the BindingsCollection.CollectionChanging event.

Syntax

protected virtual void OnCollectionChanging (System.ComponentModel.CollectionChangeEventArgs e)

Parameters

e
A System.ComponentModel.CollectionChangeEventArgs that contains event data.

Remarks

The BindingsCollection.CollectionChanging event occurs when the event is about to change.

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

The BindingsCollection.OnCollectionChanging(System.ComponentModel.CollectionChangeEventArgs) 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.

Requirements

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
