HtmlInputText.ServerChange Event

Occurs when the Value property is changed on the server.

Namespace: System.Web.UI.HtmlControls
Assembly: System.Web (in system.web.dll)

public event EventHandler ServerChange
/** @event */
public void add_ServerChange (EventHandler value)

/** @event */
public void remove_ServerChange (EventHandler value)

JScript supports the use of events, but not the declaration of new ones.

The ServerChange event is raised when the Value property is changed on the server.

NoteNote

The control must have view state enabled for the ServerChange event to work correctly.

For more information about handling events, see Consuming Events.

The following code example demonstrates how to specify and code a handler for the ServerChange event. The custom event handler updates a label on the Web page to display the value of the text entered into the <input type=text> HTML element.


<%@ Page Language="C#" AutoEventWireup="True" %>

<html>
<head>

   <script runat="server">

      void Server_Change(object sender, EventArgs e) 
      {
         Span1.InnerHtml = "You typed: " + Text1.Value;
      }

      void Page_Load(object sender, EventArgs e)
      {
         // Create an EventHandler delegate for the method you want to
         // handle the event, and then add it to the list of methods
         // called when the event is raised.
         Text1.ServerChange += new System.EventHandler(this.Server_Change);
      }         

   </script>

</head>

<body>

   <form runat="server">
