I like to have a MDI Child Form maximized in the parent form

Now when the parent form ist sized smaller than the child minimal formsize, the parent form should get scrollbars. If the child form is not maximized it works. How can i do this that it also works in maximized mode ?

regards
Chris

Try this:
don't place the controls directly on the form. Use a panel instead with AutoResize = true;
Place the Panel on the child form with Dockstyle Top.

Are there any other solutions because its a very hugh project where the forms are loaded very differently and i can't change every form.

is this a solution which can be added dynamically when showing the form ?

Took a while but finally I got it.
You can overload the OnLoad function of the child forms.
protected override void OnLoad(EventArgs e)
{
    Panel pnlMaster = new Panel();
    pnlMaster.Dock = DockStyle.Fill;
    pnlMaster.AutoScroll = true;
 
    while (this.Controls.Count > 0)
        pnlMaster.Controls.Add(this.Controls[0]);
 
    this.Controls.Add(pnlMaster);
    base.OnLoad(e);
}

Open in new window
