Is it possible to make a control global (or public) so that every window can access to that control which is located in a window. In other words, how can I access to that control within windows?

I’m not sure what your intention is, but my educated guess is that you want to update the visual state (UI) of a control instance (let’s call it C1) within a window (let’s call it W1) from other controls in other windows.
Assuming that’s the case, the .NET framework already has everything you need: Events and Delegates.
When some data changes in a window/control that should trigger a change in C1, that window/control should fire an event that C1 listens for and handles with a delegate. The UI update would happen in said delegate.
