Data Grid - Data Validation
The DataGrid UI component supports data validation against a set of predefined or custom validation rules. These rules are generated based on Data Annotations that decorate the model properties (see the EmployeeValidation.cs file). For the validation to work, the DataGrid should be cast to the model type and its columns should be declared using the AddFor()
method.
If you have technical questions, please create a support ticket in the DevExpress Support Center.

The AdditionalFields property of the Remote attribute allows you validate combinations of fields against data on the server.
In this demo, the data validation process will not be successfully completed if an already existing email is entered. To accomplish that, apply a Remote attribute to Email and include ID in AdditionalFields. The validation parameter will then have access to both ID and Email, which allows you to compare them with source data.
