Complete Source Code: https://github.com/vishipayyallore/speaker_series/tree/master/C%23/MdiAndChildDemo

Form 2:
private void button1_Click(object sender, EventArgs e)
{
    form3 = new Form3();
    form3.MdiParent = this.MdiParent;
    form3.Show();

    this.Close();
    this.Dispose();
}
Form 3:
private void button1_Click(object sender, EventArgs e)
        {
            form2 = new Form2();
            form2.MdiParent = this.MdiParent;
            form2.Show();

            this.Close();
            this.Dispose();
        }

cad sunny,
Good evening. I assume both Form2 and Form3 are the child forms for the Form1 Parent/Mdi. Please advise. Many thanks.
