Form.Activate Event
Assembly: System.Web.Mobile (in system.web.mobile.dll)
public: event EventHandler^ Activate { void add (EventHandler^ value); void remove (EventHandler^ value); }
/** @event */ public void add_Activate (EventHandler value) /** @event */ public void remove_Activate (EventHandler value)
In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.
The Activate event occurs under the following circumstances:
-
When a page is first requested, the first form is activated.
-
When the ActiveForm property of the page is set programmatically.
-
When the user navigates to a form through a Link control whose target is a form.
This event's position in the event chain makes it very important for binding child controls to data sources or for setting a form property that can be inherited by all child controls.
The following code example shows how to set the OnActivate attribute in the Form element to point to a method that executes when the Activate event occurs. The Form2_Activate method prepares the second form for display. This example is part of a larger example for the Form overview.
