DataGridViewCellCollection.OnCollectionChanged Method

Definition

Namespace:

System.Windows.Forms

Assembly:

System.Windows.Forms.dll

Raises the CollectionChanged event.

protected:
 void OnCollectionChanged(System::ComponentModel::CollectionChangeEventArgs ^ e);

protected void OnCollectionChanged (System.ComponentModel.CollectionChangeEventArgs e);

member this.OnCollectionChanged : System.ComponentModel.CollectionChangeEventArgs -> unit

Protected Sub OnCollectionChanged (e As CollectionChangeEventArgs)

Parameters

e

CollectionChangeEventArgs

A CollectionChangeEventArgs 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 OnCollectionChanged 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 OnCollectionChanged(CollectionChangeEventArgs) in a derived class, be sure to call the base class's OnCollectionChanged(CollectionChangeEventArgs) method so that registered delegates receive the event.
