When writing a simple application, I needed one of the numeric boxes to be read only, so I just changed the
ReadOnly property of
true. But after a while, I noticed that I can change the value in it, not by typing, but by using the up and down buttons.
To save people time, I posted this article presenting a simple and fast solution to the problem:
public class FixedNumericUpDown : NumericUpDown
public override void DownButton()
public override void UpButton()
