There is no built-in event for that. You have at least four choices: Any time you change $input.value in code, call the code you want triggered by the change Poll for changes Give yourself a method you use to change the value, which will also do notifications (Variant of #3) Give yourself a property you … Read more
Unfortunately there is no way to simulate a link and all associated behaviour in every browser. Therefore, the only way to achieve what you want is to have a link that follows the cursor around the <tr> element; this link would be invisible so, to the user, it looks like they’re clicking on the <tr> … Read more
From the Docs at http://api.jquery.com/triggerHandler/ The .triggerHandler() method behaves similarly to .trigger(), with the following exceptions: The .triggerHandler() method does not cause the default behavior of an event to occur (such as a form submission). Not preventing the default browser actions allow you to specify an action that occurs on focus or select, etc etc … Read more
An event is really just an “add” operation and a “remove” operation. You can’t get the value, you can’t set the value, you can’t call it – you can just subscribe a handler for the event (add) or unsubscribe one (remove). This is fine – it’s encapsulation, plain and simple. It’s up to the publisher … Read more
This is where jQuery really shines for ASP.Net developers. Lets say you have this ASP button: When that renders, you can look at the source of the page and the id on it won’t be btnAwesome, but $ctr001_btnAwesome or something like that. This makes it a pain in the butt to find in javascript. Enter … Read more
Others have explained how to get round the issue, but not why it’s coming up. When you declare a public field-like event, the compiler creates a public event, and a private field. Within the same class (or nested classes) you can get at the field directly, e.g. to invoke all the handlers. From other classes, … Read more
I use the CellContentClick event, which makes sure the user clicked the checkbox. It DOES fire multiple times even if the user stays in the same cell. The one issue is that the Value does not get updated, and always returns “false” for unchecked. The trick is to use the .EditedFormattedValue property of the cell … Read more
As you point out, where multiple threads can access SomeEvent simultaneously, one thread could check whether SomeEventis null and determine that it isn’t. Just after doing so, another thread could remove the last registered delegate from SomeEvent. When the first thread attempts to raise SomeEvent, an exception will be thrown. A reasonable way to avoid … Read more
I modified Dead.Rabit’s class EventWaiter to handle EventHandler<T>. So you can use for waiting all events type of EventHandler<T>, that means your delegate is something like delegate void SomeDelegate(object sender, T EventsArgs). public class EventWaiter<T> { private AutoResetEvent _autoResetEvent = new AutoResetEvent(false); private EventInfo _event = null; private object _eventContainer = null; public EventWaiter(object eventContainer, … Read more
I would go with present tense. Most, if not all, JavaScript frameworks seem to follow the convention set forth by the JavaScript DOM event API; i.e. to use present tense for event names. When I think about it, this seems most natural to me, despite the fact that events are handled after they are triggered. … Read more
