Convalida dei dati nelle griglie Angular

Novembre 21, 2023
La convalida aiuta a garantire che i dati immessi nella griglia siano accurati, riducendo il rischio di errori e incongruenze.

Data Validation ensures that input data meets certain criteria before it is accepted. This feature is crucial for maintaining data integrity and preventing user errors. For example, a grid might only allow date formats in a specific cell or prevent duplicate entries in a column, thereby enforcing data consistency.

Several Angular grid controls offer data validation support including:

  • Handsontable: Enforce data type restrictions, limit text input length, and set custom validation rules.
  • Jspreadsheet Pro Data Grid: Validate data against regular expressions, define custom validation callbacks, and utilize cell-level validation.
  • DataViewsJS: Implement data validation using custom data binding expressions, conditional formatting, and error messages.
  • Xceed DataGrid for JavaScript: Leverage client-side and server-side validation mechanisms, including data type checks, range limitations, and custom rules.

Alternatively, many Angular grid controls are available as part of multi-function suites:

  • DevExtreme HTML5 JavaScript Data Grid: Employ built-in data validation rules, enforce data type constraints, and handle custom validation scenarios.
  • Kendo UI for Angular Grid: Define validation rules using directives, apply data type restrictions, and utilize asynchronous validation.
  • Ignite UI Angular Grid: Implement data validation using custom editors, leverage built-in validation rules, and handle error messages.
  • SmartClient Grid: Utilize comprehensive data validation features, including data type checks, custom validation rules, and error handling.
