MDI parent and child form controls interaction.

MDI parent and child form controls interaction.

• Dorsk

  This is on MDI Form's menu click
  
  private void menuItem2_Click(object sender, System.EventArgs e)
  {
  objForm2 = new Form2(this);
  objForm2.MdiParent = this;
  objForm2.Show();
  }
  
  When you instantiate Form2, you past your MDI reference also
  
  This is on your child form :
  
  private Form1 mdiForm;
  
  public Form2(Form1 pMdiForm)
  {
  InitializeComponent();
  mdiForm = pMdiForm;
  }
  
  private void button1_Click(object sender, System.EventArgs e)
  {
  mdiForm.Text = "Change";
  }

  Thnaks a lot! Passing data (such as text) between forms is very tricky in C#. I'm used to program in VB6 and now I'm try the OOP. :)
