Form.Deactivate Event
Assembly: System.Web.Mobile (in system.web.mobile.dll)
public: event EventHandler^ Deactivate { void add (EventHandler^ value); void remove (EventHandler^ value); }
/** @event */ public void add_Deactivate (EventHandler value) /** @event */ public void remove_Deactivate (EventHandler value)
JScript supports the use of events, but not the declaration of new ones.
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.
The following code example demonstrates how to trap the Deactivate event to clear the SelectionList. This example is part of a larger example for the Form overview.
