Input Validation With ASP.NET (part 2)
Perform sophisticated pattern validation with the RegularExpressionValidator control.

| Moving On |

The first part of this series explained the importance of input validation, especially in the context of a Web-based application, and a quick overview of the types of validation controls built into ASP.NET. This was followed up by a whirlwind introduction to some useful validation controls such the RequiredFieldValidator control, RangeValidator control and CompareValidator control.

Moving on from where I left off, this concluding segment explains how you can perform more sophisticated input validation with the remaining two Validator controls, the RegularExpressionValidator control and the CustomValidator control. These two controls are not as simple as the ones you've just seen, so you'll need to have all your wits about you when we start in on them. Additionally, I'll also demonstrate how you can display a summary of input validation errors to the user instead of displaying errors as they occur, on a per-control basis.

Buckle up your seat belts and get ready for a wild ride!
