What do you mean by "Its not working" ? What isn't working.

"it's not working".. is not a helpful description of any kind of a problem. What is not working? How does it not perform to your satisfaction? Does the event handler not get called? Does the UpdateAll() method not execute? Did the city burn down when you ran this code?

It works fine for me:

C#

void ParentForm_FormClosing(object sender, FormClosingEventArgs e)
    {
    Console.WriteLine("Form closing");
    }

private void UserControl1_Load(object sender, EventArgs e)
    {
    ParentForm.FormClosing += new FormClosingEventHandler(ParentForm_FormClosing);
    }

Check that you have hooked up the Load event handler for your control.
