Raises the TextChanged event. This allows you to handle the event directly.
Assembly: System.Web (in System.Web.dll)
The TextChanged event is raised when the content of the text box changes between posts to the server.
A TextBox control must persist some values between posts to the server for this event to work correctly. Be sure that view state is enabled for this control.
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.Notes to Inheritors
When overriding in a derived class, be sure to call the base class's method so that registered delegates receive the event.
The following code example demonstrates how to override the method so that it always marks a custom TextBox server control as having been modified.
This example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview.
