Setting User Control Property Only Sometimes

I have a usercontrol that I use in multiple windows. I want to use tooltip with this usercontrol but only under one window. How do I set the tooltip to be see only under that window and not all of them. I place the tooltip under the usercontrol code. Hope that is clear enough, thanks.

Create a boolean property ShowToolTips and put its default value as false. Then in the desired window set it to true
