This can be accomplished via attached behaviors. So instead I came up with the following IgnoreMouseWheelBehavior. Technically it’s not ignoring the MouseWheel, but it is “forwarding” the event back up and out of the ListBox. Check it. /// <summary> /// Captures and eats MouseWheel events so that a nested ListBox does not /// prevent an … Read more
You can do so by returning false at the end of your handler (OG). this.canvas.addEventListener(‘wheel’,function(event){ mouseController.wheel(event); return false; }, false); Or using event.preventDefault() this.canvas.addEventListener(‘wheel’,function(event){ mouseController.wheel(event); event.preventDefault(); }, false); Updated to use the wheel event as mousewheel deprecated for modern browser as pointed out in comments. The question was about preventing scrolling not providing the right … Read more
Simplest answer: <input type=”number” onWheel={(e) => e.target.blur()} /> e is short for event. This also works: <input type=”number” onWheel={() => document.activeElement.blur()} /> Either of these can be used either in a functional or in a class component.
What worked for me was adding panel1_MouseEnter EventHandler: private void panel1_MouseEnter(object sender, EventArgs e) { panel1.Focus(); }
I recently came across this issue as well and I wasn’t finding a lot of support for it, so I quickly forgot about the problem. A few months later I saw a better example of the smooth scrolling so I went in and dug around the JavaScript files they were using and I found that … Read more
Scrolling origins An action with the mouse wheel results in a WM_MOUSEWHEEL message being sent: Sent to the focus window when the mouse wheel is rotated. The DefWindowProc function propagates the message to the window’s parent. There should be no internal forwarding of the message, since DefWindowProc propagates it up the parent chain until it … 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
There are Javascript methods, see the thread you duplicated. A better solution is to set the target div to overflow:scroll, and wrap it inside a second element that is 8px narrower, who’s overflow:hidden. The target element will have a hidden scrollbar. The mousewheel will work, but the scroll bar will not show. <div style=”overflow:hidden; width:200px;”> … Read more
Overview: While the scroll value resulting from DOM_DELTA_LINE may not be specifically defined by any specification, based on the following comment from the Chromium issue tracker and my own observations, it appears that Firefox is presently the only browser that will report wheel events with anything other than deltaMode as DOM_DELTA_PIXEL (0). Comment from Chromium … Read more
