Data Validation
Documentation
The DataGrid widget is able to validate data input within grid cells using predefined or custom validation rules. In this example, a validation rule is assigned to each column using its validationRules option. These rules do not allow an end user to enter invalid data into grid cells.
Feel free to share demo-related thoughts here.
