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.

Features are things that should be (in the opinion of the submitter) added to the product. You can break down features further into two types. First, there are the features added by the product manager as a way to assign tasks to developers. These features will normally be developed from the product s spec, as you learned in 1. Developers don t usually have a choice about these features; they must be implemented. The second type of feature comes from testers, users, managers, and other stakeholders who think they know what the product needs to make it more useful. These features have not been through the winnowing process of spec writing, and may or may not be realistic. New features from outside of the spec should first be assigned to the product manager, who can make the call as to whether they fit in this release, need to be postponed, or should never be implemented.

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).
