First, the code checks whether the item being created is an item or an alternate item. If neither, it means the item is another interface element, such as the pager, footer, or header, and the procedure does nothing. If the item is the right type, the code extracts the UnitPrice field from the data-bound item. To get a value from the bound data object (provided through the GridViewRowEventArgs.Row.DataItem property), you need to cast the data object to the correct type. The trick is that the type depends on the way you re performing your data binding. In this example, you re binding to the SqlDataSource in DataSet mode, which means each data item will be a DataRowView object. (If you were to bind in DataReader mode, a DbDataRecord represents each item instead.) To avoid coding these details, which can make it more difficult to change your data access code, you can rely on the DataBinder.Eval() helper method, which understands all these types of data objects. That s the technique used in this example. Figure 17-5 shows the resulting page.

Selecting an item refers to the ability to click a row and have it change color (or become highlighted) to indicate that the user is currently working with this record. At the same time, you might want to display additional information about the record in another control. With the GridView, selection happens almost automatically once you set up a few basics. Before you can use item selection, you must define a different style for selected items. The SelectedRowStyle determines how the selected row or cell will appear. If you don t set this style, it will default to the same value as RowStyle, which means the user won t be able to tell which row is currently selected. Usually, selected rows will have a different BackColor property. To find out what item is currently selected (or to change the selection), you can use the GridView.SelectedIndex property. It will be -1 if no item is currently selected. Also, you can react to the SelectedIndexChanged event to handle any additional related tasks. For example, you might want to update another control with additional information about the selected record.

One of the most complicated methods for building web applications is access control for multiple users. The Auth component takes care of simple authentication, but what if you wanted to have multiple layers for users and their access levels Or, better yet, what about dynamically altering a user s privileges across the site This more complex system for assigning areas for the user requires access control lists that outline a tree or matrix of who gets access to what areas in the site. The ACL component simplifies this type of user management with an assortment of functions and methods.

The GridView provides built-in support for selection. You simply need to add a CommandField column with the ShowSelectButton property set to True. ASP.NET can render the CommandField as a hyperlink, a button, or a fixed image. You choose the type using the ButtonType property. You can then specify the text through the SelectText property or specify the link to the image through the SelectImageUrl property. Here s an example that displays a select button: <asp:CommandField ShowSelectButton="True" ButtonType="Button" SelectText="Select" /> And here s an example that shows a small clickable icon: <asp:CommandField ShowSelectButton="True" ButtonType="Image" SelectImageUrl="select.gif" /> Figure 17-6 shows a page with a text select button (and product 14 selected). When you click a select button, the page is posted back, and a series of steps unfolds. First, the GridView.SelectedIndexChanging event fires, which you can intercept to cancel the operation. Next, the GridView.SelectedIndex property is adjusted to point to the selected row. Finally, the GridView.SelectedIndexChanged event fires, which you can handle if you want to manually update other controls to reflect the new selection. When the page is rendered, the selected row is given the selected row style.

Tip Rather than add the select button yourself, you can choose Enable Selection from the GridView s smart

You don t need to create a new column to support row selection. Instead, you can turn an existing column into a link. This technique is commonly implemented to allow users to select rows in a table by the unique ID value. To use this technique, remove the CommandField column, and add a ButtonField column instead. Then, set the DataTextField to the name of the field you want to use. <asp:ButtonField ButtonType="Button" DataTextField="ProductID" /> This field will be underlined and turned into a button that, when clicked, will post back the page and trigger the GridView.RowCommand event. You could handle this event, determine which row has been clicked, and programmatically set the SelectedIndex property of the GridView. However, you can use an easier method. Instead, just configure the link to raise the SelectedIndexChanged event by specifying a CommandName with the text Select, as shown here: <asp:ButtonField CommandName="Select" ButtonType="Button" DataTextField="ProductID" /> Now clicking the data field automatically selects the record.
