hi.. you can do this way..

form1 button click:

private void button1_Click(object sender, EventArgs e)
   {
   Form2 frm = new Form2();
   frm.Show();
   this.Hide();
   }

form2 's FormClosed event:

private void Form1_FormClosed(object sender, FormClosedEventArgs e)
   {
   Form1 t = new Form1 ();
   t.Show();
   }

Hi,
THis is expected behaviour. Beacuse you defined Form2 object inside Form1 i.e. Form2 object scope and life is within Form1 only.
So once Form1 closed all objects inside it will be released, including Form2 object. That's why Form2 is closing automatically.
In such scenarios you need to assign a single form, from which each form can be loaded. You can use MDI form for this purpose.
Here also once MDI form closed, all other forms will be closed automatically, it's expected behaviour.
