Remarks

You typically specify an EventHandler<HtmlEventArgs> when you require the additional event details that are available from HtmlEventArgs. Because of the overhead in fetching this information from the browser, you can instead use an EventHandler object for cases where you do not need the Document Object Model (DOM) information as part of event processing.
