How to open Child form that only locks parent form?

I want to open a child form that only locks its parent form. I can't use ShowDialog() because it locks all opened forms until dialog closes.

Main Form - Users Form - Services Form

When I open a new child form as Add New User on Users form, I want only lock Users form but I can also open Services form or any other form on Main Form.

Any suggestions?

Borrowed an idea from How-To-Prevent-Control-From-Stealing-Focus. Basically, when you open "Add New User", disable the calling form. When "Add New User" closes, enable the calling form. I put an example below.

    public partial class Form1 : Form
{
    Form2 frm2;
    Form3 frm3;
    public override bool Focused
    {
        get
        {
            return HasFocus;
        }
    }
    private bool HasFocus = false;
    public Form1()
    {
        InitializeComponent(); 

        frm3 = new Form3();

    }

    void frm2_FormClosed(object sender, FormClosedEventArgs e)
    {
        frm2.FormClosed -= frm2_FormClosed;
        this.Enabled = true;
    }



    private void button1_Click(object sender, EventArgs e)
    {
        frm2 = new Form2();
        frm2.FormClosed += frm2_FormClosed;
        frm2.Show();
        this.Enabled = false;
    }

    private void button2_Click(object sender, EventArgs e)
    {
        frm3.Show();
    }
}
