Often, a database search will return too many rows to be realistically displayed in a single page. If the client is using a slow connection, an extremely large GridView can take a frustrating amount of time to arrive. Once the data is retrieved, the user may find out it doesn t contain the right content anyway or that the search was too broad and they can t easily wade through all the results to find the important information. The GridView handles this scenario with an automatic paging feature. When you use automatic paging, the full results are retrieved from the data source and placed into a DataSet. Once the DataSet is bound to the GridView, however, the data is subdivided into smaller groupings (for example, with 20 rows each), and only a single batch is sent to the user. The other groups are abandoned when the page finishes processing. When the user moves to the next page, the same process is repeated in other words, the full query is performed once again. The GridView extracts just one group of rows, and the page is rendered. To allow the user to skip from one page to another, the GridView displays a group of pager controls at the bottom of the grid. These pager controls could be previous/next links (often displayed as < and >) or number links (1, 2, 3, 4, 5, . . . ) that lead to specific pages. If you ve ever used a search engine, you ve seen paging at work. By setting a few properties, you can make the GridView control manage the paging for you. Table 17-6 describes the key properties.

A string in PHP 5 normally allocates one byte (8 bits) per character, but in PHP 6, the strings can be Unicode 16-bit encoding. The 8-bit encodings, and any other encodings you may have used, are now considered binary format strings. New, normal strings are considered Unicode. Which one you use by default depends on a php.ini setting called unicode.semantics. When unicode.semantics is set to on, normal string literals are Unicode. When it is set to off, string literals are 8-bit binary strings. I recommend enabling Unicode semantics at this time. To see whether Unicode semantics are on or off, execute this command: > php -r "echo ini_get('unicode.semantics');"

Every time the page loads, it sets the ftpDirectory string The path is set to the FTP subfolder in the current web application directory (which is provided by the RequestPhysicalApplicationPath property) These two details (the current web application directory and the FTP subfolder) are fused together into one path string using the Combine() method of the Path class The CreateFileList() procedure is easy to code, because it uses the data binding feature of the ListBox The array returned from the GetFiles() method can be placed in the list with just a couple of lines of code The AutoPostBack property of the ListBox is set to true That way, when the user chooses an item in the list, the ListBox posts the page back immediately so the code can read the file information and refresh the file details on the page.

Enables or disables the paging of the bound records. It is False by default. Gets or sets the number of items to display on a single page of the grid. The default value is 10. Gets or sets the zero-based index of the currently displayed page, if paging is enabled. Provides a PagerSettings object that wraps a variety of formatting options for the pager controls. These options determine where the paging controls are shown and what text or images they contain. You can set these properties to fine-tune the appearance of the pager controls, or you can use the defaults.

When evaluating the FileAttributes enumeration, you need to use the & operator to perform bitwise arithmetic This is because the value returned from GetAttributes() can actually contain a combination of more than one attribute Using bitwise arithmetic, you can pull out just the attribute that you re interested in, and then determine whether it s set The code that gets the file information builds a long string of text, which is then displayed in a label For optimum performance, this code uses the SystemTextStringBuilder class Without the StringBuilder, you d need to use string concatenation to join the string together This is much slower, because every time the code adds a piece of text to the string, NET creates an entirely new string object behind the scenes The code that displays file information could benefit by switching to the FileInfo class (as shown in the next section).

As it is, every method needs to specify the same file name This is a bit tedious, and it s a bit slower because each method requires a separate security check..

Provides a style object you can use to configure fonts, colors, and text alignment for the paging controls. Occur when one of the page selection elements is clicked, just before the PageIndex is changed (PageIndexChanging) and just after (PageIndexChanged).
