Is your control hidden and you want to show it permanently again?
if so in your block diagram right click on the control and click show control
or
do you want to keep it hidden until the user clicks in a certain part of the screen?
for this you will have to use a property node for the control and use the visible property. sometimes this is handy when you want a button to show up when you click another button. for this you may need to use events and when the event fires then you enable the visible property. you could also look at events like mouse-over to unhide something when your mouse is in a certain postion but the mouse-over event must be tied to an indicator or control
