ActiveReports.NET v20はAI画像をレポートに変換し、スクリーンショットを完全に編集可能なレポートに変換して手動設計時間を短縮

ActiveReports.NET by MESCIUS is a reporting solution for the Microsoft .NET platform that enables developers to create and deliver data-driven reports in web, desktop, and cloud applications. It supports multiple report types, including section, page, and RDL (Report Definition Language) reports, and provides visual designers, a robust rendering engine, and export options such as PDF and Excel. Designed to integrate with modern .NET and ASP.NET Core applications, it helps teams build interactive, enterprise-grade reporting features into their software.

The ActiveReports.NET v20 update introduces a new AI powered image to report capability that enables developers to convert static report images such as screenshots, mockups, PDFs, or even photos of printed pages into fully editable report layouts in minutes. By leveraging Azure Document Intelligence to analyze page structure, text, and visual elements, it significantly reduces the manual effort required to recreate existing reports, accelerates the modernization of legacy assets, and streamlines migrations from other reporting platforms. This capability provides a practical starting point for rebuilding or refining reports while preserving full control over layout structure, styling, grouping, and data bindings to ensure alignment with application architecture and development standards.

ストリームからの安全なPDF読み込みを有効化

2月 16, 2026
ストリームからPDFを直接読み込みレンダリングし、クラウド、コンテナ、データベース駆動のASP.NETアプリケーションで安全かつファイルフリーに閲覧可能

Opening PDFs directly from streams in ASP.NET PDF Viewer components refers to the ability to load and render PDF documents from a .NET Stream object rather than from a physical file stored on the server. This means the PDF content can be retrieved dynamically from sources such as databases, cloud storage, web APIs, or generated in memory at runtime, and then passed directly to the viewer for display. By working with streams, applications can avoid temporary file storage, improve security by reducing file system exposure, and better support modern deployment scenarios such as containerized or cloud-based environments where local storage may be limited or transient.

Several ASP.NET Core PDF viewer components offer open PDFs from stream functionality including:

数式を壊さずに列を挿入

2月 12, 2026
ワークシート内のどこにでも簡単に新しい列を追加でき、セル参照を自動的に更新し、既存の計算も保持可能

Inserting columns in a spreadsheet allows users to expand worksheets dynamically while preserving existing data and formulas. This capability is essential for scenarios where datasets evolve over time, such as adding new fields, categories, or calculated values. A well-implemented insert columns feature ensures that cell references, formatting, and formulas adjust automatically, helping maintain data integrity and reducing the risk of errors during updates.

Several ASP.NET Core spreadsheet controls offer the ability to insert columns including:

  • DevExpress ASP.NET Core Spreadsheet (part of DevExpress ASP.NET and Blazor) enables users to insert one or multiple columns at any position in a worksheet, automatically updating formulas.
  • Telerik UI for ASP.NET Core Spreadsheet (part of Telerik UI for ASP.NET Core) allows columns to be inserted through both the user interface and APIs, ensuring that cell references are preserved.
  • Syncfusion ASP.NET Core Spreadsheet (part of Syncfusion Essential Studio Enterprise) provides options to insert columns with full support for formula recalculation.
