When child window is shown, parent window is minimized

Is it possible to make that when child window is opened, parent window is minimized and is inactive (child window is modal)? I tried changing WindowState property to minimized for parent window before calling child window, but then child window starts minimized.

Not sure why you want to do it this way, but this is doable with some trickery (or good design patterns). With trickery you can do this:

From parent (form1):

       private void button1_Click(object sender, EventArgs e)
    {
        this.WindowState = FormWindowState.Minimized;
        this.ShowInTaskbar = false;
        new Form2().ShowDialog(this);
        this.WindowState = FormWindowState.Normal;
        this.ShowInTaskbar = true;
    }

Although, I would recommend reconsidering your architecture instead.

There is a flaw in your design.

You have two top-level Windows, the main form and the child modal dialog. The child modal dialog is what is known as, in Win32 terminology, an owned window. The main form is un-owned. When a top-level un-owned Window is minimized, all the windows that it owns are hidden. That is functionality provided by the desktop window manager.

The documentation states:

An owned window is hidden when its owner is minimized.

What you are trying to do sounds unusual anyway. Normally when a form shows a modal dialog, the modal dialog is shown on top of the other form. Why are you wanting to hide the main form?

If you are dead-set on this design you need to arrange that your modal dialog is an un-owned window. When you do so it will appear as an item in the taskbar separate from your main form. Is this what you want?

In the child form_Load event, try this :

frmParent frm = new frmParent();
frm.WindowState = FormWindowState.Minimized;
