Build Your Own ASP.NET 2.0 Web Site Using C# & VB, Second Edition

We’ll expand the code inside this method in later chapters, but for the time being,

you can rest assured that you’ve put the validation mechanism in place.

Summary

As we’ve seen, the validation controls available through ASP.NET are very

powerful. This chapter explained how to validate required form fields with the

RequiredFieldValidator, compare form fields with the CompareValidator,

check for a numeric range within form fields with the RangeValidator, provide

a user with a summary of errors using the ValidationSummary control, check for

email addresses with the RegularExpressionValidator, and perform your own

custom validation with the CustomValidator.

In the next chapter, we’ll begin to introduce you to the challenges—and re-

wards!—involved in working with databases. This is a skill you’ll almost certainly

need when building any non-trivial real-world web application, so roll up your

sleeves and let’s get into it!
