Definition

protected:
 virtual void OnValidating(System::ComponentModel::CancelEventArgs ^ e);
protected virtual void OnValidating (System.ComponentModel.CancelEventArgs e);
abstract member OnValidating : System.ComponentModel.CancelEventArgs -> unit

Protected Overridable Sub OnValidating (e As CancelEventArgs)

Parameters

Remarks

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

The OnValidating 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 overriding OnValidating(CancelEventArgs) in a derived class, be sure to call the base class's OnValidating(CancelEventArgs) method so that registered delegates receive the event.
