Usa ActiveReportsJS per creare report master-detail completi che mostrano chiaramente i dati correlati e gerarchici.

ActiveReportsJS is a powerful, lightweight reporting tool designed to integrate advanced reporting capabilities into any JavaScript application. ActiveReportsJS enables developers to create, view, export, and print richly formatted reports entirely on the client side - with zero server dependencies.

In this blog post, MESCIUS Product Consultant Victor Stahlman demonstrates how to build nested data regions in ActiveReportsJS to create master-detail reports that display related data, such as customers and their orders, within a structured layout. He walks your through configuring datasets, nesting controls like Lists and Tables, and applying filters to correctly link and present hierarchical data relationships in your reports. Key topics include:

  • Growth vs. Static Data Regions
  • Understanding the Master-Detail Concept
  • Choosing the Report Type
  • Building the Report Structure

By implementing nested data regions in ActiveReportsJS, you can transform flat datasets into structured, master-detail reports that are easier to read and analyze.

Read the complete blog to get started building scalable, dynamic JavaScript reports that deliver more meaningful insights to your users.

Costruisci moduli accurati con validazione dello schema JSON

Aprile 24, 2026
Optimajet FormEngine consente la validazione in tempo reale dell'IDE e il completamento automatico, aiutandoti a individuare i problemi in anticipo e migliorare lo sviluppo dei moduli.

Optimajet FormEngine is a drag-and-drop React form builder that lets teams create, manage, and render complex web forms without writing frontend code. It allows developers and business users to visually design forms, store them as JSON, and render them at runtime. As a React JS library, it easily integrates into existing applications while giving developers full control over form logic, structure, and data flow, making it well suited for complex data collection.

Optimajet FormEngine enables JSON Schema validation for forms, allowing developers to validate form JSON directly within their IDE, identify structural issues, incorrect data types, and unsupported configurations early in the development process, and enforce a consistent, well-defined structure across all forms. By providing real-time feedback, inline error highlighting, and autocomplete suggestions, it improves accuracy and reduces the need for repeated testing cycles, helping developers work more efficiently while minimizing runtime errors and ensuring more reliable form implementations.

Optimajet FormEngine is licensed based on usage type (internal commercial use, public web/SaaS, or OEM embedding), number of domains for the visual editor, and access to additional ready-made components. Licenses are perpetual and include 6 months or 1 year of updates and support. See our Optimajet FormEngine licensing page for full details.

Annota i grafici con un contesto significativo

Migliora le visualizzazioni dei dati Vue.js inserendo annotazioni dinamiche che mettono in evidenza gli aspetti chiave e favoriscono l'analisi interattiva.

Annotation support in a Vue.js chart component refers to the capability to overlay additional contextual elements, such as labels, markers, lines, or regions, directly onto a chart to highlight specific data points, thresholds, or events. This feature enables developers to enrich visualizations with meaningful insights without altering the underlying dataset, making it easier to communicate key information such as trends, anomalies, or business rules within the UI.

Several Vue.js chart components support chart annotations, including:

  • Wijmo Vue Chart (FlexChart) (part of Wijmo by MESCIUS) lets you add configurable chart annotations that highlight data points, thresholds, and ranges.
  • DevExtreme Vue Chart (part of DevExtreme Complete by DevExpress) allows you to incorporate annotation layers into charts, supporting labels, shapes, and guides.
  • Highcharts Core by Highsoft facilitates advanced chart annotations with flexible positioning, rich styling, and event handling.
  • Kendo UI Vue Charts (part of Kendo UI Vue Charts by Telerik) enables annotation features within charts that visually emphasize key data elements.

Migliora la modifica grazie al supporto al formato RTF

Aprile 21, 2026
Abilita l'input formattato direttamente nei campi dati per rendere i contenuti più chiari, strutturati e facili da gestire.

An RTF (Rich Text Format) editor allows users to create and modify formatted text, such as bold, italics, fonts, colors, and embedded elements. This capability is particularly useful in applications where descriptive or user-generated content must retain presentation alongside data, such as CMS platforms, reporting tools, or enterprise data grids. By integrating rich text editing at the component level, it enables more expressive data entry, reduces the need for external editors, and ensures formatting consistency when storing and rendering content across systems.

Several React data editor collections include RTF (rich text format) functionality, including:

  • DevExtreme React Data Editors (part of DevExtreme Complete) facilitates formatted text input and consistent handling of styled content in applications.
  • KendoReact Data Editors (part of by KendoReact Telerik) enables formatted text entry and clear representation of content within application data fields.
  • Sencha Ext JS supports structured text formatting and consistent display of rich content in applications.
  • JQWidgets incorporates formatted input and improves how text content is captured and rendered.

Abilita le annotazioni nei PDF per un feedback più chiaro

Aprile 21, 2026
Consenti agli utenti di aggiungere note, evidenziazioni e indicatori visivi direttamente all'interno dei documenti, mantenendo il feedback chiaro e accessibile in un unico posto.

Annotation capabilities in PDF Viewer components allow users to interact with documents through visual and textual markup, supporting review, collaboration, and documentation processes. Tools such as Line, Rectangle, and Free text help highlight structure and add clarity, while Sticky note and Stamp annotations provide contextual feedback and status indicators. By embedding these capabilities directly into a viewer, applications can offer a cohesive experience for editing and reviewing PDFs without requiring external software.

Common annotations include:

  • Ellipse annotations offer a circular or oval shape tool for highlighting regions in a less rigid form than rectangular annotations.
  • Free text annotations let users insert editable text anywhere on the page for inline commentary or corrections.
  • Freehand draw (Ink) annotations enable natural, pen-like input for signatures, sketches, or handwritten notes.
  • Line annotations allow users to draw straight connectors or highlights between points, often used for pointing out relationships or alignment.
  • Rectangle annotations provide a way to frame areas of interest, making it useful for emphasizing sections of a page.
  • Stamp annotations apply predefined or custom labels, such as approval or review statuses, directly onto the document.
  • Sticky note annotations add comment markers that can store detailed feedback without cluttering the document visually.
