Remove top bar on child form

Question

Making an MDI form, i wish to remove the top bar on all child forms. Working on Visual studio and c#. Any idea how? Im clueless.

Here the properies of the child form:

Me.FormBorderStyle = Windows.Forms.FormBorderStyle.None
Me.WindowState = FormWindowState.Normal
Me.MinimizeBox = False
Me.MaximizeBox = False
Me.ControlBox = False
Me.ShowIcon = False
Me.ShowInTaskbar = False
Me.Dock = DockStyle.Fill

Option 1: ^*

As mentioned in this answer, you can add a MenuStrip control to your MDI parent form, set its Visible property to false, and you should be good to go. The MDI child forms won't have a title bar displayed as long as they are maximized.

Option 2: ^*

1. Set the MdiParent Property of the child form.
2. Set the FormBorderStyle property of the child form to FormBorderStyle.None.
3. Set the Dock property of the child form to DockStyle.Fill. Note: This must come after setting the MdiParent or else it won't work.
4. That's it, you don't need to change any other properties (WindowState, ControlBox, etc.). Just maintain the order of the steps above.

Here's an example:

private void OpenAndDockMdiChild()
{
    Form2 childForm = new Form2();
    childForm.MdiParent = this;              // This must come **before** setting 
                                             // the `Dock` property.
    childForm.FormBorderStyle = FormBorderStyle.None;
    childForm.Dock = DockStyle.Fill;
    childForm.Show();
}

private void Form1_Load(object sender, EventArgs e)
{
    OpenAndDockMdiChild();
}

Result:

Hope that helps.
