472 x CHAPTER 13 DISPLAYING AND UPDATING DATA How It Works For the most part, this exercise works the same as a previous exercise where you displayed a list with the available genres. What’s different this time is the way the SqlDataSource is able to filter the rows from the Review table based on the selection you made in the drop-down list. Take a look at the code for the SqlDataSource to see how this works: The SQL statement for the SelectCommand contains a parameter for the GenreId denoted by the @ GenreId variable in the SELECT statement. That means that the SQL statement returns rows from the Review table only for a specific genre. At run time, the value for this parameter is retrieved from the control defined in the ControlParameter element. In this example, the code is set up to get the value from the DropDownList1 control. VS knows that in order to get the selected value from the DropDownList it should access its SelectedValue property, so it adds that as the PropertyName for the ControlParameter. If you have the need to use a different property, you can simply change it in the ControlParameter element’s declaration. With this code set up, the GridView asks the SqlDataSource for its data. This data source in turn asks the DropDownList for the item that the user has selected in the list. This value is inserted in the SQL statement, which is sent to the database. The results that are returned from the database are sent back through the data source to the GridView, which uses them to create the HTML table in the browser. When you choose Make a Selection from the drop-down list, you get an empty page with no rows. In this case, the DropDownList returns an empty string as its value (defined in the Value property), which is converted to null, the database equivalent of nothing. This in turn causes the query to return no rows from the Review table. Until now, you’ve relied on the code-generation tools of VS to set up the GridView and the DetailsView. By default, VS creates a column (for the GridView) or a field (for the DetailsView) for each column that it finds in the data source. It’s smart enough to recognize some of the underlying types of the data in the data source so you get a nice CheckBoxField for boolean (bit) fields in the database, but that’s about it. To further customize the look and feel of these data controls, you need to customize their Columns and Fields collections. CUSTOMIZING THE APPEARANCE OF THE DATA CONTROLS By default, the GridView and DetailsView render columns or rows automatically based on the data they receive. Alternatively, you can have VS create a number of fields or columns for you when you attach the control to a data source. But, more often than not, you want to change what you
Customizing the Appearance of the Data Controls x 473 see on-screen, be it fewer columns, different column headings, or different controls to display data. Fortunately, this is really easy to do with the Fields editor in VS. In the next section you see how to use this editor to create and modify the different types of built-in columns and fields. In the section that follows, you see how to customize the fields even further with user-defined templates. Configuring Columns or Fields of Data-Bound Controls Within the or element of the GridView and the DetailsView, you can add the types of fields shown in the following table. FIELD TYPE BoundField ButtonField CheckBoxField CommandField HyperLinkField ImageField TemplateField DESCRIPTION The default field for most database types. It renders as simple text in readonly mode, and as a TextBox in edit mode. Renders as a link or a button enabling you to execute a command on the server. Renders as a read-only check box in read-only mode, and as an editable check box in edit mode. Enables you to set up various commands, including editing, inserting, updating, and deleting. Renders as a link (an element). You can set properties like DataNavigateUrlFields, DataNavigateUrlFormatString, and DataTextField to influence the behavior of the hyperlink. You see more of this in the next exercise. Renders as an element in the browser. Enables you to define your own look and feel for various templates, like ItemTemplate, InsertItemTemplate, and EditItemTemplate. Clearly, each field type serves a distinct purpose so you can choose the one that best fits your needs. You see some of these field types in more detail in the next exercise. TRY IT OUT Customizing GridView Columns In this exercise, you see how to do the following in the Reviews.aspx page: ‰ Use the Fields editor to customize the fields for the GridView with reviews. ‰ Use a HyperLink column to create a link to a details page that enables you to manage the details of a review. ‰ Format the output of the existing BoundField columns. ‰ Use a custom function in the Code Behind to have full control over the output in a TemplateField.
