Xceed Input Validator for .NET--part of Xceed UI
Studio for .NET--provides easy-to-use, self-wiring
text validation for your Windows Forms controls.
Simply drag and drop it onto any Windows Form to have
a validation criterion instantly added to each
compatible data input component. Each criterion can
then be configured using either the Validation
Configuration dialog or the Properties window,
allowing developers to quickly set up validation at
design time. Input components are automatically
validated at runtime.

Xceed Input Validator for .NET is compatible with
TextBox and ComboBox controls, as well as with Xceed
Grid for .NET cells (version 2.2 or later).

What if a textbox in one of your applications requires
a numerical value between 4 and 42? You can set up
this constraint with just a few clicks from your mouse
and a few keystrokes! If an end-user enters an invalid
value in an input component, a warning icon flashes
next to it. When the mouse hovers over the warning
icon, a pop-up error message explains the problem.

Error messages are fully customizable and localizable,
allowing you to explain the restrictions on input
components the way you want.

Xceed Input Validator for .NET can validate compatible
input components using .NET regular expressions,
providing endless possibilities. For example, if you
need to make sure that a user supplies a valid IP
address that is in a particular range, a regular
expression can take care of this. Again, with a few
keystrokes and mouse clicks, you can create the
validation criterion, and a regular expression tester
allows you to test it beforehand.

In addition to validating TextBox and ComboBox
controls, Xceed Input Validator for .NET can validate
Xceed Grid for .NET cells.

One of its greatest strengths is that it can add
extremely flexible input validation to compatible
components using only a single dialog box. Default and
criterion-specific error messages can be configured
with two other dialog boxes.
