I have a parent form called 'MainForm' and two other children forms (switchboard and newcustomer). I created a menubar for 'MainForm' that includes a 'SwitchBoard' item. When I run the application and click the 'SwitchBoard' menu at the top, my switchboard appears , as a child, as it should.

Now, the switchboard itself contains a button called 'New Customer'. When I click this button, I want the new customer dialog to appear as a child of 'MainForm'.

The following event handler code is inside my SwitchBoard.cs file:

private void ncButton_Click(object sender, System.EventArgs e)
{
  NewCustomer ncDialog = new NewCustomer();
  MainForm parentForm = new MainForm();
  ncDialog.MdiParent = parentForm;
  ncDialog.Show();
}

But when the button is clicked nothing happens.

How can I get my new customer dialog to show as a child of 'MainForm'?

Thanks in advance!

Never mind guys, I figured it out.

private void ncButton_Click(object sender, System.EventArgs e)
{
  NewCustomer ncDialog = new NewCustomer();
  ncDialog.MdiParent = this.MdiParent;
  ncDialog.Show();
}

Thanks anyway! :)
