How to disable mouse scroll in combobox?

3 New Member
Hi,

I have a problem with combobox. On my form is many comboboxes and when I select same option and use my mouse roll, combobox change to next value. How to disable mouse roller? I tried to change focus on another combo but it isn't good solution because you again cannot scroll page but change option in combobox. I also tried to change focus to parent -> combobox.parent .focus() but if combo is on bottom of the page view is centered and I lose current position of scrollbar. Any idea??

Click anywhere outside of your combo boxes before mouse-wheel scrolling.
That's the way it's been for years now, you've never noticed?
(I've had it change radio-button values on me...has caused me some troubles when filling out online forms)

Ok I see your point, I thought you were in a webpage.

Don't see a good way to stop it, it seems to be an OS thing, maybe you can capture the windows Message saying scroll and stop it I dunno.

Why are you making a windows application that SCROLLs....nobo dy likes to scroll.

Is there a way to disable scroll wheel support in a combobox? Basically, I have a situation where a user chooses an option in a combobox. I'm handling the selected index change event, and due to the option they chose, the combobox itself is being destroyed (dynamic UI). However, if they've managed to choose an option and then roll the scroll wheel, I'll get an unhandled exception when Windows tries to fire the events associated with...

I have quite a few of continuous form and subform where I do allow scroll bars. I run into problems with the mouse wheel whenever the data on the form does not take up the whole page. In this instance, whenever a user uses the mouse wheel to scroll down, the first record disappears off the screen and they can't get it back unless they click on the Refresh button or Page Up. The mouse wheel never scroll back up to the first record. ...

Hi, If on an asp.net page the user has just selected a value in a dropdownlist and scrolls with the wheel of his mouse, the selected value of the dropdownlist will change. How could I avoid this. So how could I disable the mouse scrolling that dropdownlist. Or how could I disable the mouse-scroll on those pages.

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
