How does one Disable the Mousewheel on a WinForm in VB.NET 2005? I have a form with some text fields and a datagridview. When the main form is active, I want to prevent the user from inadvertently scrolling to the next record. (i.e. force them to use the record navigation buttons.) However, if the datagridview has the focus, I want the user to be able to scroll through the list.
