I managed to arranged few forms to be located on 1 window form inside each panel for each forms. What I'm having problem is whenever I want to maximize the winform inside the panel to full screen, it only maximize to the panel not pc screen. Code below shows how I view the winform into the panel.

panel1.Dock = DockStyle.Fill; <------ this code somehow work to maximize it but why the form located behind instead of floating on top

What I have tried:

Quote:
con = new MySqlConnection(cs);

Centile_Chart centile = new Centile_Chart();
centile.TopLevel = false;
panel1.Controls.Add(centile);
panel1.Dock = DockStyle.Fill;
centile.Show();

As far as I know controls inside a panel cannot expand beyond the limits of the panel.

Seems it like that, or should I just put all the forms at fixed position of a parent form with default size instead put all forms inside panel?

The only form that you can maximise is the main form that has no parent; which means that the Desktop is effectively its parent. If you want to maximise a form to the entire screen then it must be a freestanding one.

the closest answer i get is using
1)form.Dock = DockStyle.Fill; <------this one only maximize to full panel
2)panel.Dock = DockStyle.Fill; <-----this one able to fill the dock of parent but it located behind other text/form

Yes, for the reasons I have already explained. You need to understand how Windows and Windows Forms actually work. Every window is a child of some other window. The ones that are on the Desktop (usually main forms) can expand to fill the screen. The ones that are children of other windows can only expand to fill their parent control, main form, panel, dialog etc.

Then you must be doing something wrong. But there is no way anyone here can guess what that may be.

1 solution

Try this:
C#
centile.TopMost = true;
centile.TopLevel = false;
centile.Dock = DockStyle.Fill;
panel1.Controls.Add(centile);
centile.Show();

centile.Dock = DockStyle.Fill;

when i use this, it only enlarge max to the size of panel instead of full screen
