Question

I have a problem with docking. Here is the thing. I hope I can explain it well.

The design of the form is like this

The form
   panelA -docked on top (there is a groupbox in this, it is also docked on top)
   panelB -docked on top
   tablist -docked fill

The thing is, panelB needs to be in the middle. The visibility of panelB is controlled by a combobox in panelA. So, when the user selects anything in combobox(in panelA), the panelB is visible and loaded with the associated user control.

The Document Outline is

The form
  tablist
  panelB
  panelA

They are on the same level but not the same order with the design. I don’t know why.

The problem is, I make panelB visible=false in constructor, and make it visible again in combobox_selectedIndexChanged. But the panelB appears to be on top of panelA. After making it visible, this is how it looks;

the form
  panelB
  panelA
  tablist

How can I fix this?

Answer 1

Try this sequence after making panelB visible to true:

panelA.BringToFront();
panelB.SendToBack();
