title: How to prevent key entry with NumericUpDown control?
body: <p>I have a numericupdown control on a winform and I noticed while testing that not only you have the option of changing the value by pressing up and down key but also simply entering the values from your keyboard. </p>
  
  <p>I don't want that. I only want the user to be able to change the numericupdown's value only by clicking the up and down buttons within the box.</p>
  
  <p>So far I simply can't find a solution. </p>
  
  <p>Does anyone know how to do this?</p>
