Donnez aux utilisateurs les outils pour facilement mettre en forme le texte dans les applications Angular

Novembre 27, 2023
Améliorez vos applications Angular avec un éditeur de texte enrichi et une interface intuitive pour créer et modifier sans effort du contenu mis en forme, sans avoir à coder.

Rich Text Format (RTF) editors allow users to create and edit text with a variety of formatting options, such as font styles, colors, headings, lists, and images. Often used in web and desktop applications, such editors provide a WYSIWYG (what you see is what you get) interface, so users can see how their text will look as they format it. This allows formatted editing without the complexity of HTML markup or the need for separate word processing software.

Several Angular data editor collections provide RTF editing capabilities including:

  • DevExtreme Complete Data Editors (part of DevExtreme by DevExpress) empowers your Angular apps with rich text editing capabilities, including formatting options and image insertion.
  • Kendo UI for Angular Data Editors (part of Kendo UI by Telerik) helps users craft engaging content directly within your Angular applications, featuring comprehensive formatting tools and seamless integration.
  • Syncfusion Essential Studio for JavaScript Data Editors (part of Syncfusion Essential Studio Enterprise) offers a rich array of formatting options and intuitive image integration.
  • jQWidgets Data Editors (part of jQWidgets) provides extensive formatting controls, image insertion and link embedding functionalities.
  • SmartClient Data Editors (part of SmartClient by Isomorphic Software) features comprehensive text formatting tools including font type and size, text color and alignment.

Gardez les colonnes importantes visibles dans les grilles React

Novembre 27, 2023
Implémentez une fonctionnalité de gel des colonnes pour garantir la visibilité même lorsque les utilisateurs font défiler horizontalement de grandes grilles.

Locked column functionality (also known as frozen or pinned column) allows users to keep one or more columns static while scrolling horizontally through a grid. This is an essential feature for comparing data across a wide grid, ensuring that key information, such as a row identifier column, remains in view.

Several React grid components offer column freezing functionality including:

  • DevExtreme HTML5 JavaScript Data Grid (part of DevExtreme Complete by DevExpress) can pin key columns for easy reference while scrolling through wide datasets.
  • Wijmo FlexGrid (part of Wijmo by MESCIUS) freezes columns to maintain the visibility of essential data during horizontal scrolling.
  • Ignite UI React Grid (part of Infragistics Ignite UI) keeps critical columns in view while scrolling horizontally through extensive data.
  • KendoReact Data Grid (part of KendoReact by Telerik) locks columns for persistent visibility when scrolling extensively across data.
  • Syncfusion Grid control for JavaScript (part of Syncfusion Essential Studio Enterprise) freezes columns for continuous access to important data during horizontal scrolling.

Validation des données dans les grilles Angular

Novembre 21, 2023
La validation permet de s’assurer que les données saisies dans la grille sont exactes, réduisant ainsi le risque d’erreurs et d’incohérences.

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.
