You can call a method on from1 when from2 closes like this:
in Form1 write this:
public void MyrefeshMethod()
{
MessageBox.Show("refreshed");
}
and in the Form2 closed event write this:
private void Form2_FormClosed(object sender, FormClosedEventArgs e)
{
Form1 frm = new Form1();
frm.MyrefeshMethod();
}
hope this helps :)
