Cool. What else The review might be too short. Too short Like, blank, or fewer than ten characters, say. . . .and so on. With these rainy-day scenarios typed up as alternate courses, our Write Reader Review use case should now look like this: BASIC COURSE: The Customer clicks the Write Review button for the book currently being viewed, and the system shows the Write Review screen. The Customer types in a Book Review, gives it a Book Rating out of five stars, and clicks the Send button. The system ensures that the Book Review isn t too long or short, and that the Book Rating is within one and five stars. The system then displays a confirmation screen, and the review is sent to a Moderator, ready to be added. ALTERNATE COURSES: User not logged in: The user is first taken to the Login screen and then to the Write Review screen once he is logged in. The user enters a review that is too long (text > 1MB): The system rejects the review and responds with a message explaining why the review was rejected. The review is too short (< 10 characters): The system rejects the review.

If you re testing this web page in a modern browser (such as Internet Explorer 5 or later), you ll notice an interesting trick. When you first open the page, the error message is hidden. But if you type an invalid number (remember, validation will succeed for an empty value) and press the Tab key to move to the second text box, an error message will appear automatically next to the offending control. This is because ASP.NET adds a special JavaScript function that detects when the focus changes. This code uses the special WebUIValidation.js script library file that is installed on your server with the .NET Framework (in the c:\Inetpub\wwwroot\aspnet_client\system_web\[Version] directory) and is somewhat complicated. However, ASP.NET handles all the details for you automatically. If you try to click the OK button with an invalid value in txtValidated, your actions will be ignored, and the page won t be posted back. These features are relatively high-level, because they combine DHTML and JavaScript. Clearly, not all browsers will support this client-side validation. To see what will happen on a down-level browser, set the RangeValidator.EnableClientScript property to False, and rerun the page. Now error messages won t appear dynamically as you change focus. However, when you click the OK button, the page will be returned from the server with the appropriate error message displayed next to the invalid control. The potential problem in this scenario is that the click event handling code will still execute, even though the page is invalid. To correct this problem and ensure that your page behaves the same on modern and older browsers, you must specifically abort the event code if validation hasn t been performed successfully.

To examine how to use some of the techniques discussed so far, let s look at the ScreenSizes/EU4You sample application. This application has one activity (EU4You) that contains a ListView with the roster of European Union (EU) members and their respective flags (http://www.wpclipart.com/flags/Countries/index.html). Clicking one of the countries brings up the mobile Wikipedia page for that country. In the source code to this book, you will find four versions of this application. We start with an application that is ignorant of screen size and slowly add in more screenrelated features.

This code solves the current problem, but it isn t much help if the page contains multiple validation controls. Fortunately, every web form provides its own IsValid property. This property will be False if any validation control has failed. It will be True if all the validation controls completed successfully or if validation was not performed (for example, if the validation controls are disabled or if the button has CausesValidation set to False).
