how to prevent the controls in a form and form itself to scroll?

[Guest]

Hi All,

I have a MDI form application. In a child form I placed a bunch of
NumericUpDown controls. The problem happens when I use the mouse scroll
button, the value in the NumericUpdown has changed and the form also scrolls
out of control. How do I make the detatch those two types of controls so that
only one gets the mouse scrolling event. I tried to override the OnMouseWheel
event for the NumericUpDown, it seems that it did not get fired. I also try
to let the NumericUpDown to loose control,-- no success!

Thanks much!

MH,

Normal an event is binded to one control. Did you maybe do some code to get
this general doing?

Thanks! But No, the NumericUpDown is just a standard control I picked up from
the toolbox under windows form and placed it in a form. when the program
runs, if you click mouse inside the NumericUpDown, you can change value use
either arrow key, clicking up/down button, or just the scroll the mouse. The
trouble is I can not make the NumericUpDown loose focus and let the form
capture the mouse scroll.
