Display Settings PropertiesImmediate validation
Description
Specify if the value in the field should be validated as soon as you tab out of the field, or in the case of radio button, dropdown or checkbox controls, as soon as you change a value. The 'server-side' option will generate an Ajax callback, so you should try to limit the number of fields that require real-time server-side validation.
- Client-side only
Only validation rules defined on the client (via Validation Javascript) are applied.
- Client-side and server-side
The control is immediately validated using both server-side and client-side validation rules after the user modifies the value.
- None
The default value. No validation is performed until the user submits the changes.

Data Validation
The Grid component has exceptionally strong data validation features. This video demonstrates the validation features available, including Data validation rules, Data validation using custom Xbasic at the field level, Data validation events, and automatically honoring Field Rules for DBF tables.
Validating Data
The UX Component has an extremely rich set of features for validating data in the component. Validation rules can be defined declaratively, or by using code (either Javascript for client-side or Xbasic for server-side). Validation rules are evaluated on the client where possible (thus eliminating the need for an Ajax callback). Validation rules can be set to fire when the dialog is submitted, or immediately when the user tabs out of a field.
These video discuss the various validation options in the UX Component.
The videos below discuss the validation features of Alpha Anywhere. While these videos were recorded for the UX Component, the discussions about Validation rules, Validation Xbasic, and Immediate Validation apply to the Grid Component.
