There are two things. "Hide" and "Close" and both have different meanings.. Over the top, there are things like MODAL and NON-MODAL dialogs.

What do you really want to achieve? and what have you tried so far..

Nayan is right.
Besides, there are no parent and child form. Most likely, you concern is about closing non-main form. My question is: do you want to exit the application when this form is closed or not?

You need to clarify your question: which Form is the "Main Form" ? Are you actually making a Form the "child" of another Form by setting the Form's Parent property ?

Do you want to show any of the Forms modally ? And, so on.

Main Form

C#

namespace cp5
{
    public delegate void dHide(bool hide);
    public partial class MainForm : Form
    {
        public MainForm()
        {
            InitializeComponent();
        }
        void Button1Click(object sender, EventArgs e)
        {
            Form1 fm1=new Form1();
            fm1.delfunc+=hideform;
            fm1.Show();
        }
        void hideform(bool hide)
        {
            if (hide) this.Hide();
            else this.Show();
        }
    }
}

and child form to hide/show main form:

C#

namespace cp5
{
	public partial class Form1 : Form
	{
		public dHide delfunc=null;
		public Form1()
		{
			InitializeComponent();
		}
		void Button1Click(object sender, EventArgs e)
		{
			delfunc(true);
		}
		void Button2Click(object sender, EventArgs e)
		{
			delfunc(false);	
		}		
	}
}
