title: Winform - Override textbox to show sample text and clear on click
body: <p>I have a windows form with textfields. I would like that the textbox shows sample text and when i click on the textbox, the text is cleared. What is the best way to do this?</p>
  
  <p>e.g. the form shows text: 192.18.130.44, as the user clicks on that textbox, the text is cleared.</p>
