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.

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?

推荐答案

如果要执行此操作，则必须在第二个面板中维护对第一个面板的引用:创建一个类级别的面板可变，并在其中隐藏该面板，将引用保存到您刚刚隐藏的面板.然后，您可以使用它稍后显示面板.

You have to maintain a reference to the 1st panel in the second if you want to do this: Create a class level Panel varaiable and where you hide the panel, save the reference to the panel you just hid. You can then use this to show the panel later.

private Panel myOtherPanel = null;
...
theOtherPanel.Visible = false;
myOtherPanel = theOtherPanel;
...
if (myOtherPanel != null)
   { 
   myOtherPanel.Visible = true;
   }
