How to detect when owner form is closed from an inner control?

Question

How to detect when owner form closes (from a control inside it)?

UPD I need the control to know that it's form is closing, not vice versa

Answer 1

Credits to Fredrik Mörk for this solution:

FindForm().FormClosing += parentForm_FormClosing;

Answer 2

You should intercept FormClosing event. In FormClosingEventArgs the variable CloseReason will show you why is the form closing. Your best bet is intercepting when this variable equals UserClosing enumerated value.
