HiddenField.ValueChanged Event
.NET Framework 3.0
Occurs when the value of the HiddenField control changes between posts to the server.
Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)
Assembly: System.Web (in system.web.dll)
public: event EventHandler^ ValueChanged { void add (EventHandler^ value); void remove (EventHandler^ value); }
/** @event */ public void add_ValueChanged (EventHandler value) /** @event */ public void remove_ValueChanged (EventHandler value)
In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.
The ValueChanged event is raised when the value of the HiddenField control changes between posts to the server. This allows you to provide an event-handling method that performs a custom routine whenever this event occurs.
For more information about handling events, see Consuming Events.
The following example demonstrates how to use the ValueChanged event to display the value of the HiddenField control.
