C # hides and shows a panel on top of a separation container

Question

I have a screen that is divided by several separation containers. One of them contains rectangles that I created custom components, these "rectangles" are hospital beds. I would like to give users the ability to switch between this “custom component view” and the “datagrid” view.

So, I created the pnlPatients panel, which I give to the size of the shared container with custom components. When the user selects "Change View", the program should switch between the two layouts.

Code: Attempt 1:

if (pnlPatients.Visible)
  pnlPatients.Hide();
else
{
  pnlPatients.Show();
  pnlPatients.BringToFront();
}

Attempt 2:

pnlPatients.Visible = !pnlPatients.Visible;
pnlPatients.Invalidate();

It is strange that both attempts work like this:

" ". , . , . , . : TRUE FALSE. - , TRUE, .

- ?

: , :

pnlPatients.Visible = !pnlPatients.Visible;
if (pnlPatients.Visible)
{
  pnlPatients.BringToFront(); 
}
else
{
  pnlPatients.SendToBack();
}
