Select the Border all Controls command from the Options menu to cause a border always to be displayed around your controls in Painter.
If you define any control property with a border style of none and those controls have the same background color as the form, they are invisible when they are not selected. Selecting the Border all Controls command identifies the position of your controls on forms.
This command does not affect the status of your control borders at run time.
