Visual Studio button not appearing (Obv C#)

if you are using winforms, and manualy (in code) adding the button. Make sure the parent control adds the button to its Controls list. if the parent control is a form you can do:

Controls.Add(button); // where button is your button

Controls.Add(button); // where button is your button
