Add MDI child from another MDI child

For doing this the MdiParent property for the new child has to be set from another child form. Please refer the below code snippet which illustrates this.

C#

private void buttonAdv1_Click(object sender, EventArgs e)
{
   Form3 child1 = new Form3();
   // Set the new form's MDI parent to main form
   child1.MdiParent = (Form1)this.Parent.Parent;
   child1.Text = "Document";
   child1.Show();
}

VB

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
   Dim f1 As Form3 = New Form3()
   ' Set the new form's MDI parent to main form
   f1.MdiParent = CType(Me.Parent.Parent, Form1)
   f1.Text = "Document"
   f1.Show()
End Sub
