In some cases I have found, developers unwire event then wire it again like this:
control.Click -= new eventHandler(eventHandler)
control.Click += new eventHandler(eventHandler)
why do they do that?
Possibly because there is other code in between that will trigger the event, and they don’t want
eventHandlerto act on it. IMHO this isn’t the best way to do things, but it’s easy and it works.If there is no other code in between there cannot possibly be a reason to remove and add the same event handler again.
