See the Windows Forms Events Lifecycle:
- Move: This event occurs when the form is moved. Although by default, when a form is instantiated and launched, the user does not move it, yet this event is triggered before the Load event occurs.
- Load: This event occurs before a form is displayed for the first time.
- VisibleChanged: This event occurs when the Visible property value changes.
- Activated: This event occurs when the form is activated in code or by the user.
- Shown: This event occurs whenever the form is first displayed.
- Paint: This event occurs when the control is redrawn.
- Deactivate: This event occurs when the form loses focus and is not the active form.
- Closing: This event occurs when the form is closing.
- Closed: This event occurs when the form is being closed.
