Finally, imagine that you want to break the tax form into multiple pages so that a person views only one part of the tax form at a time. XVIII In the following sections, you learn about the properties that you can use to hide and display controls in a form. You learn how to use the Visible and Enabled properties with individual controls and groups of controls to hide and display page content. Using the Visible and Enabled Properties Every control, including both HTML and Web controls, has a Visible property that determines whether the control is rendered. When a control39。ll find it easy to make the transition between the two languages. XIV NOTE Microsoft includes an interesting tool named the IL Disassembler (ILDASM) with the .NET framework. You can use this tool to view the disassembled code for any of the classes in the Temporary Files directory. It lists all the methods and properties of the class and enables you to view the intermediatelevel code. This tool also works with all the controls discussed in this chapter. For example, you can use the IL Disassembler to view the intermediatelevel code for the TextBox control (located in a file named ). Introducing Controls controls provide the dynamic and interactive portions of the user interface for your Web application. The controls render the content that the users of your Web site actually see and interact with. For example, you can use controls to create HTML form elements, interactive calendars, and rotating banner advertisements. controls coexist peacefully with HTML content. Typically, you create the static areas of your Web pages with normal HTML content and create the dynamic or interactive portions with controls. The best way to understand how controls work in an HTML page is to look at a simple Web Forms Page. Adding Application Logic to an Page The second building block of an page is the application logic, which is the actual programming code in the page. You add application logic to a page to handle both control and page events. If a user clicks a Button control within an HTML form, for example, the Button control raises an event (the Click event). Typically, you want to add code to the page that does something in response to this event. For example, when someone clicks the Button control, you might want to save the form data to a file or database. Controls are not the only things that can raise events. An page itself raises several events every time it is requested. For example, whenever you request a XV page, the page39。s overall .NET framework, which contains a vast set of programming classes designed to satisfy any conceivable programming need. In the following two sections, you learn how fits within the .NET framework, and you learn about the languages you can use in your pages. The .NET Framework Class Library Imagine that you are Microsoft. Imagine that you have to support multiple programming languages— such as Visual Basic, JScript, and C++. A great deal of the functionality of these programming languages overlaps. For example, for each language, you would have to include methods for accessing the file system, working with databases, and manipulating strings. X Furthermore, these languages contain similar pro
