jQuery Editors Windows UI Theme  
Display validation errors on a field to ensure correct entries. 

All editors feature complete validation support so that you can stop data submissions that don't meet your fundamental business rules, where it is least costly to stop invalid data–in the client's browser. The validation support also includes the capability to display a validation error inline that will automatically disappear when the field is validated after being corrected by the end user.

Just set the culture information and our jQuery editors take on the customary format of data values that local end users expect, resulting in a seamless localization experience for your global Web applications.

Update the editor properties so that data values entered reflect the local language.  
Prompt users to enter text in a particular field with watermark-type suggestions. 

Editors can be displayed with a watermark (or prompt text for when it has a null value) which disappears as soon as the editor receives focus. If the end user sets focus elsewhere on the page without specifying a value, their prompt text will reappear to encourage them to fill-in a value.

Support for spin buttons as an option on our jQuery editors to give end users an alternative means of incrementing or decrementing the editor's value. If you bind a list of values to a text editor, end users can use the spin buttons to select one of the choices in that list just as if it were a dropdown – without the dropdown!
