Set DataGridView2 as public and write following code in Botton_Click of Form1 :

var frm2 = new Form2();
frm2.dataGridview2.DataSoure = this.dataGridView1.DataSource;
frm2.Show();

Answer 2

use this on Form1 button Click

var form = Application.OpenForms.OfType<Form2>().FirstOrDefault();
if (form != null)
{
  Form tempChild = form;
  DataGridView dd = (DataGridView)tempChild.Controls["datagridview2 of form2"];
  dd.DataSoure = this.dataGridView1.DataSource;
