クラスのClick ReturnValueプロパティをに設定するtrueことによって、要素のイベントの既定のアクションを取り消すことができます。 HtmlElementEventArgsYou can cancel the default action for a Click event on an element by setting the ReturnValue property of the HtmlElementEventArgs class to true.

HtmlDocument BubbleEventまた、 HtmlElementEventArgsクラスのプロパティをに設定しない限り、要素のイベントは、その要素の親要素およびクラス自体でも発生します。true ClickA Click event on an element will also occur on that element's parent elements and on the HtmlDocument class itself, unless you set the BubbleEvent property of the HtmlElementEventArgs class to true.

現在入力フォーカスClickがない要素をユーザーがクリックすると、イベントはイベントのFocusing後、その要素のイベントのLostFocus前に発生します。If the user clicks on an element that does not currently have input focus, the Click event will occur after the Focusing event, but before the LostFocus event for that element.
