Realce dados nas células com formatação condicional

Dezembro 6, 2023
Aplique indicações visuais a células, linhas ou colunas específicas com base em seus valores de dados, facilitando a identificação de padrões e tendências.

Conditional formatting in grids allows users to apply visual styles to cells or ranges based on the data they contain. It enhances data readability and analysis by highlighting critical values, outliers, or trends in a data-driven manner. For instance, a cell might be colored red if it contains a value below a certain threshold, thereby drawing attention to potential issues.

Several WinForms grid components support conditional formatting including:

  • DevExpress WinForms Data Grid (part of DevExpress WinForms) enhances data visualization with rich conditional formatting rules including custom visual styles.
  • FlexGrid for WinForms (part of ComponentOne Studio WinForms by MESCIUS) enables conditional cell styles, visual indicators and data-driven formatting.
  • Infragistics WinDataGrid (part of Infragistics Ultimate UI for Windows Forms) includes sophisticated formatting rules, conditional cell backgrounds, and data-driven visual cues.
  • NOV Grid for .NET (part of Nevron Open Vision for .NET) provides custom formatting expressions, data-driven cell styles and conditional background colors.
  • Telerik UI for WinForms GridView offers rule-based cell formatting, visual indicators, and data-driven formatting logic.

Mantenha colunas importantes visíveis nas grades do React

Novembro 27, 2023
Implemente a funcionalidade de congelamento de colunas para garantir a visibilidade mesmo quando os usuários rolam horizontalmente por grades grandes.

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.

Validando dados em grades Angular

Novembro 21, 2023
A validação ajuda a garantir que os dados inseridos na grade sejam precisos, reduzindo o risco de erros e inconsistências.

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.
