Permita que os usuários abram e gerenciem PDFs no aplicativo

Julho 3, 2025
Permita que os usuários visualizem, anotem e gerenciem documentos PDF diretamente em seu aplicativo, eliminando a necessidade de software de terceiros.

PDF reading and writing capabilities in viewer components are essential for applications that handle document management or display. These features allow developers to integrate PDF interaction directly into web or desktop applications, enabling end-users to open, view, annotate, and sometimes even modify PDF files without relying on external software. By supporting both the consumption and output of PDF content, these components improve workflows across document-heavy environments, such as enterprise reporting, legal systems, and educational platforms.

Common features include:

  • Printing/saving to PDF allows users to convert viewed documents or application content into PDFs or store existing files for offline access.
  • Printing PDFs to a printer enables direct output of documents to physical printers with accurate formatting and pagination.
  • Localization ensures the viewer interface adapts to multiple languages, facilitating global user adoption.
  • Right to Left (RTL) support is critical for users of languages such as Arabic or Hebrew, aligning UI and text layout appropriately.
  • Searching text provides in-document search capabilities, letting users find specific terms or phrases quickly within large PDFs.
  • Opening existing PDFs from stream allows developers to load documents directly from memory or server streams, improving performance and enabling secure or dynamic content delivery.

Adicione insights instantâneos com minigráficos incorporados

Julho 2, 2025
Os minigráficos oferecem um visual compacto de mostrar tendências diretamente nos relatórios, ajudando você a identificar padrões rapidamente sem usar grandes gráficos.

Sparklines are compact, data-rich graphics embedded within reports to illustrate trends, variations, or patterns over time. These miniature charts, typically rendered as lines, columns, or bars, offer a concise visual summary without the need for full-scale graphs. By integrating sparklines directly into data tables or summaries, reporting tools enable users to quickly grasp performance metrics or fluctuations at a glance, enhancing the interpretability of complex datasets.

Several React reporting controls offer sparklines including:

  • DevExpress Reporting offers the XRSparkline control, which can be bound to data sources and configured to display various chart types such as line, bar, area, and win/loss.
  • ActiveReportsJS by MESCIUS provides a Sparkline control with multiple visualization options, including line, column, whisker, area, and stacked bar types.
  • Stimulsoft Reports.JS includes a Sparkline component with line, area, column, and win/loss charts, plus configurable points and color options for tailored report visuals.

Simplifique o gerenciamento de dados relacionais

Julho 2, 2025
O SmartClient da Isomorphic Software fornece uma solução no-code para exibir, editar e atualizar relacionamentos de dados automaticamente.

SmartClient is a comprehensive JavaScript component suite compatible with React, Vue, Angular, and more, that allows you to create large-scale, high-productivity web applications. It provides a comprehensive set of tools for developers, including advanced UI components, robust data management capabilities, and integration with modern backend technologies. Key features include dynamic data fetching, customizable grids, and a responsive interface for a wide range of devices. SmartClient enables developers to create applications with optimized performance, scalability, and a superior user experience. Ideal for enterprise-grade use cases, such as financial analytics, inventory management, and real-time reporting, SmartClient empowers organizations to deliver feature-rich applications that handle complex data requirements with ease.

Relations connect objects to each other and are used in databases and systems that are object-oriented. SmartClient lets you declare these relations in your data source using Relation Fields, providing a full access to related data without the need to write additional code. With two new user interface (UI) components for editing related records and the Relation Fields feature, it is now easier to manage many-to-many relationships. "MultiPickerItem" is a compact control used for inline form editing where the selected values appear inline and a pop-up displays checkboxes to enable users to select from a related data source. The Shuttle Interface can be embedded in any layout, including forms and modals, and provides a visual dual-panel interface for handling multi-item associations. These features simplify the management of relational data, offering users a declarative, scalable, and user-friendly approach.

SmartClient is licensed per developer and is available as both perpetual and subscription licenses. Product updates and technical support is also available. See our SmartClient licensing page for full details.

Use gráficos de Gantt para coordenar tarefas urgentes

Julho 1, 2025
Os gráficos de Gantt mapeiam tarefas ao longo do tempo, ajudando as equipes a gerenciar cronogramas, detectar conflitos e manter a visibilidade de cronogramas de projetos complexos.

A Gantt chart is a visual project management tool that displays tasks or activities along a timeline, allowing teams to see the start and end dates, duration, and dependencies of each task within a project. Typically represented as horizontal bars across a calendar-based axis, Gantt charts provide a clear overview of project progress and help identify potential bottlenecks or scheduling conflicts. Gantt charts improve planning, scheduling, team coordination, and stakeholder transparency by clearly organizing tasks and timelines. They are especially valuable in complex projects, offering both macro and micro views to support informed decision-making and efficient execution.

Several JavaScript chart controls provide Gantt charts including:

  • AnyGantt JS by AnyChart allows you to build feature-rich Gantt charts for project tracking, including task grouping, critical paths, and interactive controls.
  • FusionCharts Suite XT lets you create interactive Gantt charts that visualize task timelines, dependencies, and progress with rich, customizable styling.
  • Syncfusion JavaScript Chart (part of Syncfusion Essential Studio Enterprise) provides dynamic Gantt chart support with drag-and-drop scheduling and real-time task updates.
  • DevExtreme Chart (part of DevExtreme Complete by DevExpress) facilitates Gantt chart rendering, enabling task planning with milestone tracking and zoomable time scales.

Renderize linhas de grade dinamicamente na rolagem

Junho 30, 2025
Use a rolagem virtual e infinita para renderizar conteúdo visível dinamicamente, melhorando o desempenho de sua grade de dados em aplicativos JavaScript.

The ability to load items in a data grid as you scroll is a technique where content is rendered or fetched dynamically based on the user’s scroll position. Its purpose is to improve performance, and ultimately the user experience, when dealing with large datasets. This includes virtual scrolling, where the grid only renders rows that are currently visible in the viewport and reuses those same DOM elements as the user scrolls, and infinite scrolling (also known as endless scrolling), where additional data is loaded from a remote source in response to reaching the end of the currently displayed dataset. By minimizing the amount of data rendered or retrieved at any one time, this approach significantly reduces initial load times, improves responsiveness, and allows applications to scale efficiently.

Several JavaScript grid components allow you to load items as the user scrolls, including:

  • DevExtreme HTML5 JavaScript Data Grid (part of DevExtreme by DevExpress) supports both virtual and infinite scrolling to optimize data loading performance.
  • KendoReact Data Grid (part of KendoReact by Telerik) offers customizable column/row virtualization and virtual scrolling, dynamically requesting data as needed.
  • Sencha Ext JS Grid (part of Sencha Ext JS) implements infinite scrolling through a virtualized system that loads data on demand without traditional pagination.
  • Syncfusion DataGrid for JavaScript (part of Syncfusion Essential Studio Enterprise) allows both virtualization and infinite scrolling for responsive grid rendering.
