panel help with a class

Hi Guys

Hope you can help me ! I have a application that opens a instance of a class called controller class each time you click on a different treeview node. the class then creates a panel in a tabpage. In my Controllerclass i references another class (Commentclass) creating a other panel with different controls on. My problem is that when i reference Comment class I make the 1st panel visibility false but when i want to make it true from comment class i cant

Can anyone please advice?


Thanks
