Remarks
A form becomes inactive under the following circumstances:
When the ActiveForm property of the page is programmatically set to another form.
When the user navigates to a form through a Link control whose target is a form.
If neither of these actions occurs, the active form will never receive a Deactivate event. This event's position in the event chain makes it very important in resetting the child controls, data set, or global variables.
