494 x CHAPTER 13 DISPLAYING AND UPDATING DATA as soon as your page grows, it is increasingly important to choose distinguishing names for your controls. ‰ Consider setting the CssClass of the validation controls in AddEditReview.aspx and hook them up to a CSS class. You can create them in a style sheet in the Styles folder in the root for now and link that file to the master page. In a later chapter you create a separate theme for the Management section. SUMMARY This chapter built on the general knowledge you gained in Chapter 12 about accessing a database through SQL. It started off with a discussion of the numerous controls in the Data category of the Toolbox in Visual Studio. These controls can be split into two groups: data-bound controls and data source controls. The first group of controls—including the GridView, the DetailsView, and the ListView—is used to display data in a web page. Most, but not all of them enable you to maintain your data as well, by exposing inserting, updating, and deleting capabilities. The controls in the other group, the data source controls, have no visual appearance themselves. They serve as a bridge between the user interface and the database. A number of different data source controls exist, each providing access to a specific kind of data store. In this chapter you saw the SqlDataSource control, which enables you to retrieve data from many different kinds of relational databases. EXERCISES 1. If you need to create a user interface that enables a user to display, filter, edit, and delete data coming from a database, what is the best control to use? How do you hook up that control to the database? 2. Which control would you pick if you want to display a simple list of the genres in your database in the following format? Punk Hard Rock Jazz Techno 3. What’s the difference between a BoundField and a TemplateField? When would you use which of the two? 4. What’s the best place to store your connection strings? How do you access the connection strings from that location? And why shouldn’t you store them in a page? You can find answers to these exercises in Appendix A.
Summary x 495 ⊲ WHAT YOU LEARNED IN THIS CHAPTER Connection string Data source controls Data-binding expression syntax Data-bound controls Expression syntax InsertParameters UpdateParameters DeleteParameters Named instance SelectParameters A string containing information necessary to connect to a database such as SQL Server A set of ASP.NET controls that serve as a bridge between a data source (a database, an XML file, and so on) and the data-bound controls Syntax used to bind values from data sources to control properties such as labels and text boxes. Example: Text='' Bind is used for two-way binding, whereas Eval is used to display readonly data A set of ASP.NET controls that can display flat and hierarchical data A terse syntax to bind a variety of sources, including connection strings from the Web.config file, to control properties. Example: ConnectionString= "" A set of parameters used to feed data into the data source controls to support insert, update, and delete behavior The name of a specific SQL Server instance. Used to distinguish between multiple installations of SQL Server on the same machine A set of parameters that can get their data from other sources (a query string, a cookie, and so on) and that can be used in the data source controls to filter data
