Is there any way to retreive a list of events of a DOM in Javascript? e.g. I register FuncA, FuncB, FuncC for the onclick event using AddEvent or AddEventListener methods. How do I get the reference of all these functions for that onclick event? Ideally, I want to have a function like this: eventList = getEvents(obj, 'onclick'); a...
I'm trying to figure out how to wrap a boost::function member (used as an event callback) of an unmanaged class with a C++/CLI class event. I do not have control over the unmanaged class. All I can do is figure out how to write the C++/CLI class properly. Here's the example unmanaged class: class X { public: boost::function<void ...
If actions is a Panel, am I able to raise the Click event of it's parent? I have this code at the moment, but the Click event isn't a method, so this code is invalid. Does anyone know how I can achieve this? actions.Click += delegate(object Sender, EventArgs e) { ((Panel)Sender).Parent.Click(); } ...
I dynamically load a UserControl into a View that's in a MultiView control. Although the UserControl adds an event handler, the event never fires. What am I missing here? Thanks!

Hi, I'm migrating some code from VB.NET to C# (3.5). I find structurs like: Public Event DataLoaded(ByVal sender As Object, ByVal e As EventArgs) Protected Sub Mag_Button_Load_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Mag_Button_Load.Click [..] RaiseEvent DataLoaded(Me, EventArgs.Empty) End Sub [..] 'Other C...
I've heard that it's no good idea to make elements global in JS. I didn't understand why. Is it something IE can't handle? For example: div = getElementById('topbar'); ...
I'm throwing this out there just as a question of curiosity... Assuming you're only expecting/wanting one method to be provided, would this be frowned upon or bad practice? public class Something { public Action OnRemove = () => { }; public Action<object, EventArgs> OnFinishedLoading = (sender, e) => { }; } // then used like....
According to the official documentation, the KeyDown event on a Windows Forms control occurs only once, but it is easy to demonstrate that the event fires continually aslong as a key is held down: private void textBox1_KeyDown(object sender, KeyEventArgs e) { label1.Text = string.Format("{0}", globalCounter++); } H...
I have a ListView where each item has a checkbox. Initially there are no events attached and I set the state of the checkboxes programatically.

I've been playing around with assigning an ASP.NET WebControl's DataSource when I'm handling its DataBinding event. For general data binding logic in my pages, it seems to work well in organizing things. What arguments are there for not doing this? ...
I understand the purpose of events, especially within the context of creating user interfaces. I think this is the prototype for creating an event. public void EventName(object sender, EventArgs e); but I don't understand event handlers, specifically what they do, why they're needed, and to create one. Could someone please enlighten m...

Say that I have a web user control that has several drop down lists in it. They are all set to AutoPostBack = true, BUT each SelectedIndexChanged event handler in my control will fire/chain the other SelectedIndexChanged handlers I have defined for the other DDLs. This means that when the user changes a single DDL, the event handlers are...

I am a senior level developer but I haven't had a lot of formal training and I although I have used many design patterns and seen them used in my years as a developer, no one really went out of their way to say. "Oh this is an observer pattern, or this is a Singleton pattern." Reading over some of the design patterns, I came across the ...
I need to send some events to a component in Swing, so it is handled just like any user generated, standard Swing events. Basically, something like a macro recorder, and then executor for JEditorPane. But I need more control over the generated events. SO, assume I have an editor, I want to: capture all events sent to it, and at that...

Maybe I'm just an idiot, but I can't seem to find an event that will fire for a textbox at the same time as the leave, but only when the contents of the textbox has changed. Kinda like a combination of textchanged and leave. I can't use textchanged cause it fires on each keystroke. Right now I'm storing the current value of the textbo...
