Hi im new to c# and i cant figure out how to change what appears in the new childform window that appears when u click the new button. th coding i have so far is

private void ShowNewForm(object sender, EventArgs e)
{
// Create a new instance of the child form.
Form childForm = new Form();
// Make it a child of this MDI form before showing it.
childForm.MdiParent = this;
childForm.Text = "Window " + childFormNumber++;
childForm.Show();
}
