HiddenField::ValueChanged Event
Occurs when the value of the HiddenField control changes between posts to the server.
Assembly: System.Web (in System.Web.dll)
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 NIB: Consuming Events.
The following example demonstrates how to use the ValueChanged event to display the value of the HiddenField control.
