C# – Child Form is hidden behind MDI Parent Container

cmdinetvisual studiowinforms

When a child form is opened it is hidden behind the title bar of MDI Parent Container.

enter image description here

The Child form's WindowState is set to Maximized. FormBorderStyle is set to None.

If I minimize the MDI parent and maximize it, then the child form comes in to front.

How to overcome this situation?

Edit:

I use the following code to open a child form.

    this.childForm= new ChildForm();
    this.childForm.MdiParent = this;
    this.WindowState = FormWindowState.Maximized;

    this.childForm.Dock = DockStyle.Fill;
    this.childForm.Show();
    this.childForm.BringToFront();
    this.childForm.Focus();

Try the following code.

    Form1 newMDIChild = new Form1();
    newMDIChild.MdiParent = this;
    newMDIChild.Show();
    this.LayoutMdi(MdiLayout.Cascade);
    newMDIChild.Dock = DockStyle.Fill;

R – How to make a child form resize when its MDI parent form is maximized

use a custom event - when the parent changes window state to maximized, it raises the event; child forms attach to the event and maximize themselves

of course this begs the question of "why would you want to do this?" since only the last child to maximize itself will be visible...

.net – Problem with icon on creating new maximized MDI child form in .NET

A slight modification to Calanus' solution:

    private void MdiBase_Load(object sender, EventArgs e)
    {
        // Fixes bug where loading form maximised in MDI window shows incorrect icon.
        this.Icon = Icon.Clone() as Icon;
    }

This allows you to set the icon at design time (just as you would for other forms), and does not need any hard-coded file or resource accessing.
