The validation solutions you ve seen so far work well, but they tend to be code-heavy. To validate different controls, you almost always need to create separate Validating event handlers, because each control requires its own validation logic and its own error message. Clearly, in an application with dozens of forms and hundreds of input controls, this approach isn t very convenient because it forces you to write a huge amount of custom validation code. You might try to solve this by writing generic validation routines that handle the Validating event for multiple controls. Unfortunately, there s no easy way to keep track of the error message and validation rules that you want to apply for each control. If you needed only one controlspecific piece of information, you could store it in the handy Control.Tag property. For example, you could use the Tag property to store an error message for each control, or a custom regular expression to use for validation. Unfortunately, you can t store both pieces of information at least not without making it impossible for developers to enter the validation expression and error-message information using the Properties window at design time, which is the real goal. Fortunately, there is a solution, and it already exists in the .NET Framework. Unfortunately, the solution is designed for a completely different platform ASP.NET Web pages. Although you can t use the ASP.NET validation controls in a Windows Forms application, you can learn a lot about the best way to encapsulate validation logic. With a little additional effort, you can even build your own set of validation controls that provides the same functionality.

Note There is another potential solution that s not pursued in this chapter you could create a custom extender provider to implement the customized validation. This extender provider could work like the ErrorProvider, but perform the validation as well as the error display. You ll learn more about extender providers in 25, and you can find a detailed example of this technique (in VB code) at http:// msdn.microsoft.com/library/en-us/dnadvnet/html/vbnet04082003.asp.

The goal of the ASP.NET validation controls is to create a straightforward, reusable validation framework that allows you to set validation rules declaratively. In other words, you drag a validator onto a form, connect it to an existing control, and set a few properties to determine how the validation will be performed. All of these steps unfold at design time. Best of all, you don t need to write any validation code at all. Clearly, validation controls allow you to be more productive. Validation controls also simplify your application because they encapsulate common validation tasks like checking for blank values, comparing numbers, and using regular expressions. Because the validation controls handle this basic infrastructure, you don t need to write (and repeat) this code yourself. Considering that validation code is usually scattered throughout countless different forms, you can see how validation controls can help you dramatically cut down the total amount of code in your application. ASP.NET provides five core validators, which are shown in Table 18-6.

Validation succeeds as long as the input control doesn t contain an empty string. Validation succeeds if the input control contains a value within a specific numeric, alphabetic, or date range. Validation succeeds if the value in an input control matches a specified regular expression. Validation succeeds if the input control contains a value that matches the value in another, specified input control. Validation is performed by an event handler you write.
