NumericTextBox
The Telerik NumericTextBox Extensions for ASP.NET MVC are a set of four components designed to control the input of numeric, currency or percentage entries: NumericTextBox, IntegerTextBox, PercentageTextBox, CurrencyTextBox. They automatically handle the parsing of values that the users enter and format their values when displayed.
While each of the Telerik ASP.NET MVC NumericTextBox components has its own unique features, designed to support a particular data type, they all share a number of common features, so that you can take advantage of the same rich set of options, no matter what type of data you want to collect.

Key features include:
- Client-side and server-side validation
- Support for edit templates of ASP.NET Dynamic Data driven websites
- Rich client-side API and events
- jQuery-based animations
- Keyboard navigation
- Globalization
