Activated

Raised when the form receives focus. The form also publishes this event when you call the form Activate( ) method.

Deactivate

Raised when the form loses focus.

FormClosed

Raised when the form is closed by the user, by the form Close( ) method, or by the static Exit( ) method on the System.Windows.Forms.Application class.

FormClosing

Raised as the form is closing, but before the FormClosed event is raised. You can set the Cancel property on the FormClosingEventArgs parameter when handling this event to cancel the close of the form and prevent the FormClosed event from being raised.

Load

Raised before the form is displayed for the first time, allowing you to allocate resources for and further configure the form before it actually becomes visible.

Shown

Raised immediately after the form is displayed for the first time.
