Imposta le colonne come obbligatorie nelle app della griglia dati

Maggio 16, 2025
Utilizza i controlli per le griglie in JavaScript per definire le colonne obbligatorie, assicurandoti che i campi essenziali siano compilati per mantenere un input completo e valido.

A fundamental feature in a data grid is the ability to specify that a column must be populated with values and cannot be left empty. By designating certain columns as mandatory, developers can enforce input rules that prevent users from leaving critical fields blank, such as user identifiers, product names, or timestamps. Required columns are typically enforced through validation rules that prevent the submission or processing of incomplete records, thereby ensuring the completeness and validity of data entries. This improves data integrity, reduces the likelihood of processing errors, and supports consistent business logic across applications that rely on structured datasets.

Several JavaScript grid controls allow you to set columns as required, including:

  • Wijmo FlexGrid (part of Wijmo by MESCIUS) is a JavaScript data grid that allows columns to be marked as required, including built-in validation logic to ensure compliance.
  • Jspreadsheet Pro Data Grid (part of Jspreadsheet Pro) supports the use of validation rules to ensure entries meet predefined criteria, enabling you to define mandatory fields.
  • SmartClient Grid (part of SmartClient by Isomorphic Software) equips JavaScript apps with required column configuration to prevent the submission of incomplete records.
  • Ignite UI Angular Grid (part of Infragistics Ignite UI) offers developers an out of the box validator to enforce the population of required columns during data entry.

I grafici ad alto contrasto aumentano l'accessibilità, migliorando la comprensione e l'inclusività di report, dashboard e presentazioni.

High contrast charts use distinct and contrasting color palettes within data visualizations to improve clarity, particularly for individuals with visual impairments. This involves choosing colors with noticeably different hues and brightness for elements such as lines, bars, labels, and backgrounds, so that differences in data are easy to spot. These charts improve data understanding, make information accessible to more people, reduce eye strain for some users, and support accessibility standards. They are useful in many areas, such as financial reports, scientific papers and public health dashboards that must be clear and designed for a everyone regardless of visual ability.

Several JavaScript charting components provide accessible high contrast features, including:

  • JSCharting renders accessible high contrast charts, enhancing data clarity and inclusivity for users with visual impairments across diverse applications.
  • SmartClient Chart by Isomorphic Software offers built-in high contrast themes, ensuring visually impaired users can effectively interpret complex business data.
  • jQWidgets Chart enables the creation of high contrast data visualizations, improving comprehension and accessibility for a broader audience in web applications.  
  • Highcharts Core by Highsoft facilitates the implementation of customizable high contrast charts, promoting inclusivity in data representation for all users.
