ASP.NET provides a variety of validation Web controls that can be used to validate a user's form field inputs. Unfortunately, the validation Web controls do not work with the CheckBox or CheckBoxList Web controls. If you set a validation control's ControlToValidate property to the ID of a CheckBox or CheckBoxList, the page will throw an HttpException, stating: "Control 'controlID' referenced by the ControlToValidate property of 'validationControlID' cannot be validated."

There may be times, however, when you need to provide validation for a CheckBox or CheckBoxList. Many Web pages with Terms of Service include a CheckBox titled "I agree to the above terms" that must be checked before continuing. Likewise, a Web Form may contain a set of options in the form of a CheckBoxList. Perhaps the user is required to check at least one of these options before continuing.

In this article we'll create two custom server controls, CheckBoxValidator and CheckBoxListValidator. The download at the end of this article includes both the entire source code and a compiled assembly that you can drop into your ASP.NET 2.0 web applications..

In this article you learn how this can be accomplished.
