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.
