Hi,
I’ve found a problem that when the mouse is hovered over a NumericUpDown control and the mouse wheel scrolled, the NumericUpDown will change value even if the NumericUpDown does not have the focus.
It’s the same in WinForms, the wheel changes the NumericUpDown when the mouse point is over the control, it doesn’t have to be focused since the wheel events are dispatched to the control under the mouse.
Checked DevExpress ASPNET Ajax controls and Sencha ExtJS and there it’s different, the wheel changes the value only if it has the focus.
Looks like it’s an implementation choice. I’ll see if we can add an option or change it to behave like ExtJS.
