I highly recommend you use this jQuery plugin: PLUGIN Without a plugin, try this example: EXAMPLE HTML: <div id=’foo’ style=”height:300px; width:300px; background-color:red”></div> Javascript: $(‘#foo’).bind(‘mousewheel’, function(e) { if(e.originalEvent.wheelDelta / 120 > 0) { alert(‘up’); } else { alert(‘down’); } }); There is no scrollbar on the div but the wheel event is detected.
I suspect the OP wants to get scroll events when just the mouse is hovering over the panel even though the panel does not have the focus. A way to accomplish this behaviour is explained here: http://social.msdn.microsoft.com/forums/en-US/winforms/thread/eb922ed2-1036-41ca-bd15-49daed7b637c/ and here: http://social.msdn.microsoft.com/forums/en-US/winforms/thread/6bfb9287-986d-4c60-bbcc-23486e239384/ One of the code snippets taken from the linked forum: using System; using System.ComponentModel; using … Read more
I know it’s a really old post, but here is a good solution I made : function handle(delta) { var animationInterval = 20; //lower is faster var scrollSpeed = 20; //lower is faster if (end == null) { end = $(window).scrollTop(); } end -= 20 * delta; goUp = delta > 0; if (interval == … Read more
You can also create a behavior and attach it to the parent control (in which the scroll events should bubble through). // Used on sub-controls of an expander to bubble the mouse wheel scroll event up public sealed class BubbleScrollEvent : Behavior<UIElement> { protected override void OnAttached() { base.OnAttached(); AssociatedObject.PreviewMouseWheel += AssociatedObject_PreviewMouseWheel; } protected override … Read more
This may help you.. private void ListViewScrollViewer_PreviewMouseWheel(object sender, System.Windows.Input.MouseWheelEventArgs e) { ScrollViewer scv = (ScrollViewer)sender; scv.ScrollToVerticalOffset(scv.VerticalOffset – e.Delta); e.Handled = true; }
Use the MouseWheel event for your ComboBox: void comboBox1_MouseWheel(object sender, MouseEventArgs e) { ((HandledMouseEventArgs)e).Handled = true; } Note: you’ll have to create event in code: comboBox1.MouseWheel += new MouseEventHandler(comboBox1_MouseWheel);
Update 2: My solution is based on disabling the browser’s native scrolling altogether (when cursor is inside the DIV) and then manually scrolling the DIV with JavaScript (by setting its .scrollTop property). An alternative and IMO better approach would be to only selectively disable the browser’s scrolling in order to prevent the page scroll, but … Read more
There’s no “stop” event here really – you get an event when you do scroll, so every time a mousewheel event happens the event is triggered…when there’s nothing you’ll get no events and your handler won’t be firing. You ca however detect when the user hasn’t used it in say 250ms, like this: $(“#myElem”).mousewheel(function() { … Read more
HTML5 Canvas The HTML element is used to draw graphics, on the fly, via JavaScript. The element is only a container for graphics. You must use JavaScript to actually draw the graphics. Canvas has several methods for drawing paths, boxes, circles, text, and adding images. In general, to scroll the mousewheel up and down we … Read more
Due to several VCL constructs (whether they are deliberate implementation choices or may possibly be bugs1), I leave in the middle) only the focused control and all its parents get mouse wheel messages, as well as the control which has the mouse captured ánd has a focused parent. At the TControl level, the latter condition … Read more
