Advanced Input Validation

Many of the errors encountered during data input can be addressed via the use of masks and editor capabilities - such as limiting input string length, specifying maximum and minimum allowed values, etc. But editors cannot solve all potential problems associated with data entry. In such instances, the DXEditors Library provides you with flexible input validation mechanism.

With the DevExpress Data Input Validation system, you can introduce the following features to your WPF application(s):

• Specify when data validation should take place: with each text modification operation, on Enter key press or when trying to move focus away from the editor.
• Optionally block focus transition to other controls until a valid value is entered.
• Automatically display an animated error icon and corresponding tooltip showing the error message.
