The Peter's More Validators Module

• MultipleRequiredControlsValidator - Tests several fields to determine how many have been filled in (not “blank”). It supports these rules: All, All or none, Only one, At least one, and a range.
• DifferenceValidator – Evaluates two TextBox fields to determine if the difference between their two values is a certain number apart from each other. You select the data type (including dates), a value to compare and the operator. For example, test that two dates are less than 60 days apart.
• CompareToStringsValidator – Tests a field’s textual value against a list of strings. If the text matches one of the strings, it is valid. For example, you want to have the user type an answer of "Bird", "Cat" or "Dog". It allows you to use a datasource (DataSet, DataTable, ArrayList) to populate the list of strings.
• CharacterValidator - Tests a field’s textual value to confirm that each character is in a character set that you specify. For example, you require a password to be letters, digits, and underscores only. This validator doesn’t care about the order or pattern of characters.
• WordCountValidator – Evaluates the number of words in a TextBox against a minimum and/or maximum. It can evaluate the number of words combined in two TextBoxes, if desired.
• SelectedIndexRangesValidator - Evaluates the selected index of a ListBox, DropDownList, RadioButtonList, or CheckBoxList against a list of ranges. This way, you can have several valid selected indexes.
• CountSelectionsValidator – Evaluates CheckBoxLists and multi-selection ListBoxes to determine how many items are selected. You can establish a minimum and maximum.
• CountTrueConditionsValidator – Lets you define a list of conditions for a number of fields. Evaluates how many of those conditions are true and compares them to a minimum and maximum. A common usage is with a list of checkboxes (not using a CheckBoxList) to emulate the CountSelectionsValidator.
• ListSizeValidator - Evaluates the number of items shown in a listbox or dropdownlist. Typically used when the user interface allows adding and removing items in a list, where you have a minimum or maximum for the number of items shown.
• CreditCardNumberValidator – Confirms that the pattern is valid for credit card numbers. Its evaluation rules confirm that the text is all digits, follows Luhn’s formula, and if desired, matches specific brands of credit cards. It does not provide credit card number approval software.
• ABARoutingNumberValidator – Confirms that the pattern is valid for ABA routing numbers such as check routing numbers. It confirms that the text is always 9 digits that are confirmed with a checksum rule defined by the American Bankers Association.
• DuplicateEntryValidator - Determines if three or more TextBoxes, DropDownLists, or ListBoxes have a matching value. It reports an error when a duplicate is found.
• UnwantedWordsValidator – Compares a list of words to the text. It reports an error when any of the words is found within the text. Use it to block bad language and other words that are inappropriate. It has rules to catch words where letters are separated by other characters like, if you are looking for "jerk", you will find it in "j*e!r$k".
