NumericUpDown - large step by mouse wheel

[Karel]

Hello,

is there any way how to change NumericUpDown control so that mouse wheel would do large step instead of small step? (users would like to add 10 by mouse wheel but only 1 by up/down arrows)

 

Thanks,

Karel

Hello Karel,

The control does not provide a mechanism for altering this default behavior. What I can suggest you as a possible solution would be to inherit the default RadNumericUpDown control and override its OnMouseWheel method. Can you please give it a try?

Hopefully, this helps.

Thanks, I tried it and it works very well. Here is code I used (for someone else):

public class CustomRadNumericUpDown : RadNumericUpDown
    {
        protected override void OnMouseWheel(MouseWheelEventArgs e)
        {
            HandleMouseWheel(e.Delta);
        }

        private void HandleMouseWheel(int delta)
        {
            if (delta > 0)
                ChangeValue(LargeChange);
            else
                ChangeValue(-LargeChange);
        }
    }
