310 x CHAPTER 8 USER CONTROLS ⊲ WHAT YOU LEARNED IN THIS CHAPTER @ Control directive @ Register directive AlternateText Machine.config User Control View State Properties ViewState collection A set of instructions that marks a file as a User Control and define its behavior. Used to register user controls and point to their source inside pages, master pages, and other user controls. The property that enables you to set the alt attribute on images that is shown when the image cannot be displayed. The central .NET configuration file that applies to your entire system and provides defaults for your website’s settings. A block of content (stored in a file with an .ascx extension and an optional Code Behind file) that can be reused in pages, master pages, and other user controls in your site. Properties at the page, master page, or user control level that store their values in View State so they can survive postbacks. The ViewState collection is the property on the Page, UserControl, and MasterPage classes that enables you to store and retrieve values using View State.
9Validating User Input WHAT YOU WILL LEARN IN THIS CHAPTER: ‰ What user input is and why it’s important to validate it ‰ What ASP.NET 4.5 has to offer to aid you in validating user input ‰ How to work with the built-in validation controls and how to create solutions that are not supported out of the box ‰ How to send e-mail using ASP.NET ‰ How to read text files WROX.COM CODE DOWNLOADS FOR THIS CHAPTER You can find the wrox.com code downloads for this chapter on the Download Code tab at www.wrox.com/remtitle.cgi?isbn=1118311809. The code is in the Chapter 9 download. So far you have been creating a fairly static website where you control the layout and content by adding fixed pages to the site and its navigation menus. But you can make your site a lot more attractive by incorporating dynamic data. This data usually flows in two directions: it either comes from the server and is sent to the end user’s browser, or the data is entered by the user and sent to the server to be processed or stored. Data coming from the server can be retrieved from many different data sources, including files and databases, and is often presented with the ASP.NET data controls. You see how to access databases in Chapter 12 and onward. The other flow of data comes from the user and is sent to the server. The scope of this information is quite broad, ranging from simple page requests and “Contact Us” forms to complex shopping cart scenarios and wizard-like user interfaces, but the underlying principle of this data flow is basically the same in all scenarios—users enter data in a Web Form and then submit it to the server.
