You create a Microsoft ASP.NET application by using the Microsoft .NET Framework version 3.5.
You create an AJAX-enabled Web form by using the following code fragment.

When the updFirstPanel UpdatePanel control is updated, a dynamic client script is registered.
You write the following code segment in the code-behind file of the Web form. (Line numbers are included for reference only.)
01 Protected Sub Page_Load(ByVal sender As Object, _ ByVal e As EventArgs)
02 If Not IsPostBack Then
03 Dim generatedScript As String = _
| English | Chinese | Japan | Korean | - 75 - Test Information Co., Ltd. All rights reserved. ScriptGenerator.GenerateScript()
04
05 End If
06 End Sub
You need to ensure that the client-script code is registered only when an asynchronous postback is issued on the updFirstPanel UpdatePanel control.
