While this code produces the expected behavior of "1" when touching the screen: document.getElementById('someNodeId').addEventListener('touchmove', touch, true); function touch(evt) { evt.preventDefault(); alert(evt.changedTouches.length); } the same code using a jQuery selector: $('#someNodeId').bind('touchmove', touch)...
Hi, I have the code included below that allows me to do something the first time a user mouses over an element and then remove the event. It plays nice in the W3C event model browsers but keeps throwing an error in IE6-8. I got the code from another question and believed it would handle IE. Anyone see what I'm doing wrong? <scrip...
I noticed that the asp:Button for example will work without javascript enabled in the browser. However any other control with an "OnClick" or "OnServerClick" event must use the javascript_doPostback. Are there any controls besides the Button that don't need to use javascript? I want to know because I want to be able to style the ...

Hey guys I am trying to overwrite a event handler of MouseWheel for a ScrollViewer. Since ScrollViewer is sealed, I cant simply create a "custom" class inheriting it. I guess the generic question would be: "How do I overwrite the default event." (Or something like that ;-)) Edit: The event which should replace the default "scroll" only...
Hi, I'm looking through a plugin that somebody else has written and for some reason all my click event handlers are destroyed. I'm going through the code and there are several uses of unbind which I've commented out to determine whether it is causing the issue. Unfortunately that is not enough, so I'm wondering if there are other ways...
I want to know if a control has a method assigned on the Click event. Button b = new Button(); b.Click += (sender, e) => { }; /* What I want */ b.Click.Count // 1 I need something that can at least tell me if the control has or not some method on the click event. ...
Hello folks, I have one page with two dropdownlists with different IDs and in my codebehind I have two distinct methods, one for each dropdownlist, with distinct names and handlers. BUT, in my codebehind, only one dropdownlist calls it's method - and sometimes it calls both methods! - while the other dropdownlist never calls its method...
If you want to get mousemove events over a group of controls in a window, it seems there are a couple of ways to do this, but none are very clean. The hacks I've seen: Application.AddMessageFilter; Blatantly check all events coming to the window. (difficult to limit to a specific part of the program.) Recursively hook up handlers to e...
I realized that on a webpage, when a form's UI (checkbox, dropdown list, etc) is changed programmatically, the event handler (onchanged) is not fired? Is this a standard rule -- that when a control is changed programmatically, the event handler will never get triggered? Is there any exception? ...
In Codegear C++ Builder, I'm trying to extend the TMemo VCL class to perform some functionality during the OnKeyDown event. I've set up the control and am able to add it to forms and so forth. The problem is that I am unable to capture the OnKeyDown event (or any other event, for that matter). Here is my class: class PACKAGE TREMemoFin...

First question is what is the proper way to unsubscribe? If the subscribe looks like this: Panel1.MouseClick += new MouseEventHandler(Action_MouseClick); is it proper to unsubscribe like this...
I have: $('#myTextArea').keyup(function(e) { if(e.keyCode == 13) { e.preventDefault(); // Makes no difference $(this).parent().submit(); // Submit form it belongs to } }); How do I prevent the newline that shows up right before form submission? preventDefault() and stopPropagation don't work. I could manually rese...
I created a link with static text. That works fine but now I also want to change the text when you click the link. I got as far as this: add(new Link("doAnything") { @Override public void onClick() { // change the text! // this.modelChanging(); // this.detach(); } }); I hope you can giv...
I have a textbox tbx. For it I had an event handler: public void tbxPress(object sender, KeyPressEventArgs e) { MessageBox.Show("message 1"); if (e.KeyChar == 13) // i.e. on Enter { MessageBox.Show("message 2"); } } and it worked perfect until I set AutoCompleteMode parameter of tbx....
I am attempting to share a sub menu among several different parts of an application so that it is consistent (not wanting to copy/paste.) I thought it would be simple. I am doing something like this: public class MyClientClass Private WithEvents ctx As ContextMenuManager = New ContextMenuManager Private Sub handler() Handles ...
In Silverlight 4, I wish to invoke one of the mouse button click events when the right mouse button is clicked. I have the RightMouseButtonDown click event wired up, but I don't know how to manually fire the MouseLeftButtonUp event.
