Is there any way of getting a list of registered listeners for an EventDispatcher? I know that EventDispatcher has the hasEventListener method to tell you if any listeners are registered, but is there an easy way of interrogating the EventDispatcher to find out what the listeners are? One way I figured to do this was to subclass Event...
Because of the issue explained in this question I have a situation where I need to attach the mousewheel event to the drop down list only when it is expanded (I do this in the onclick event). However I need to remove the mousewheel event when the list collapses. How do I go about detecting this? I can't just use the onchange event becau...

I've been doing some work lately on a project that makes extensive use of events. One of the things that I need to do is asynchronously call multiple event handlers on a multicast delegate. I thought the trick would be to call BeginInvoke on each item from GetInvocationList, but it appears as though BeginInvoke doesn't exist there. Is t...
It's a somewhat broad question, and for that I apologise, however I am struggling to get to grips with an approach for turning an overly complex (read: poorly designed) ASP.NET WebForms application into something more maintainable. I believe it can be transformed into something which is largely event-driven. I don't mean events as in th...
I'm working on a project where I'd place an search box with a default set of results, over the layout using Prototype which is triggered from a click event. When the output is set, that new page has it's own Javascript which is uses, to dynamically filter the results. Now the new set of results do not work with the Javascript set previ...

I'm cutting my teeth on events and delegates today and to do so, I have been toying with the idea of experience bars, those progress bars from games. But I have a question about the better way to solve my problem - it could be as simple as bad design. Let me provide you some details. I have modelled my idea with an ExperienceBar class. ...
I have a PreviewKeyDown handler on my mainwindow which handles up and down keys so I can navigate with the keyboard between my controls. Now I have the problem that in some Textboxes I also want to use the up/down keys. This seems impossible because the other handler seems to swallow the keys first. Is it possible that when one of thes...
I have a modal box window (pop-up) that contains an iframe, and inside that iframe there's a div that is scrollable. When I scroll the iframe's inner DIV, and it has reached its top or bottom limit, the window of the browser itself starts to scroll. this is an unwanted behavior. I've tried something like this, which kills the main win...

I have been looking for descriptions of events "Preview**" like every element has events KeyDown and PreviewKeyDown. What is difference (not that one is attached event and one is not, the real conventional difference and programming way difference) In any class derived from Control, you can override both methods.. OnKeyDown and OnPrevie...

Hi, This might be a very dumb question but I can't find an answer anywhere. I was wondering how do you handle events in Django. I've read the tutorial in their webpage and I cant find a sign of explanation or I'm missing it. I work in ASP.NET webforms and the way to do that, as you probably know, is putting the event name in the ASP.NE...
Hi, I try to detect the event on a mapview. I just need to detect zoom (double tap or 2 fingers on screen).

I've browsed through the questions on the site, but haven't found a decent answer yet. My problem is that my main form class is cluttered due to all the events and methods.
