The first chapter, "An Introduction to the DataGrid, DataList, and Repeater," discusses for the uses of these controls, the similarities and differences among them, and when you could expect to use these controls in real-world scenarios.
The second chapter, "Binding Data to the Data Controls," examines how one binds data to the control, and what kind of data can be bound to a data Web control.
Finally, the third chapter, "Customizing the HTML Output," looks at how to tweak the HTML output by these controls to customize the appearance of the control in the user's browser.
In Chapter 4, "Adding Buttons and HyperLinks to the DataGrid Web Control," we'll look at how to add Button and HyperLink columns— two Column types mentioned in the first chapter—to the DataGrid. The generic Button column is useful for associating some kind of action with each row in a DataGrid. The HyperLink column can be used to provide a simple data-bound hyperlink for each row. For example, you could use a DataGrid to display a list of products your company sells, with each row in the DataGrid having a link that takes the user to a "Details" page featuring extensive information about a particular product.
In Chapter 5, "Adding Command Buttons to the Data Web Controls," we'll cover how to create special types of controls in templates that trigger a specific event when clicked. With these controls you can provide, among other things, simple update and delete capabilities. Specifically, we'll examine how to provide such functionality in a DataList control.
In Chapter 6, "Using External Web Controls to Achieve Effects on the Web Control," we'll examine how Web controls not directly associated with the data Web control have an effect on the data Web control. For example, you might have a DataList that displays all of your company's products, but you would like to allow the user to filter the results so that she only sees products of a certain category. To accomplish this, you can present the user with a RadioButtonList containing one radio button for each product category. When the user selects a specific category from the list, the page is posted back and the DataList only shows those products that have the specified category.
In Chapter 7, "Sorting the DataGrid's Data," we will examine just how to sort data in a DataGrid; likewise, in Chapter 8, "Providing DataGrid Pagination," we will look at adding pagination support to the DataGrid, ignoring the task of paging through sorted data.
In Chapter 10, "Putting it All Together: A Real-World Example," we will see how to meld the concepts learned in Chapters 7, 8, and 9. This chapter will present a single ASP.NET Web page that allows the user to sort, page through, edit, delete, and add additional data. By the end of Part III, you will have mastered the more useful and advanced features of the DataGrid Web control.
In Chapter 12, "Creating Custom Column Controls for the DataGrid," we will look at how to create our own column controls for the DataGrid. Commonly, the programming logic performed by a DataGrid custom column control can accomplished by providing code in the ASP.NET server-side code.
