インタラクティブなPDFフォームを直接ビューア内で入力・送信することで、手作業の手順を減らし、データの正確性が向上

Filling forms in a PDF viewer lets users complete interactive fields such as text boxes, checkboxes, radio buttons, and dropdowns directly in the document, without needing additional software. The viewer captures data in a structured format, which can help reduce entry errors and eliminate the need to print and scan forms. As a result, documents can be completed and returned more quickly, supporting paperless processes and simplifying day-to-day operations for both organizations and end users. Common use cases include contracts and agreements, job applications and onboarding forms, customer intake documents, compliance paperwork, and internal approval processes.

Several .NET PDF Viewers feature support for form filling, including:

.netCHARTING 10.8は、最新の.NETプラットフォームにデータ可視化エンジンを移植し、開発者が最新のグラフ作成ソリューションを構築可能

.netCHARTING is a comprehensive charting solution designed for C# and VB.NET developers working with ASP.NET or WinForms. It enables the rapid creation of dynamic, data-driven charts with minimal coding effort. Built entirely with managed C# code, .netCHARTING seamlessly integrates data access, aggregation, and visualization, allowing developers to generate interactive and visually compelling charts from various data sources, including SQL Server, Oracle, and MySQL. The platform supports a wide array of chart types - such as bar, line, pie, and geographic maps - and offers features like JavaScript and HTML5 charting for enhanced interactivity across devices, including mobile platforms. By automating complex tasks like date handling and data aggregation, .netCHARTING simplifies the development process, enabling professionals to deliver insightful data visualizations efficiently.

The .netCHARTING 10.8 release introduces official .NET 10 support with a dedicated NuGet package and sample bundle that run on the latest Microsoft tooling, enabling developers to build and optimize visualizations on the newest cross-platform .NET platform. This update ensures compatibility with the latest Visual Studio 2026 and Windows Server environments, letting teams leverage the performance and productivity improvements of .NET 10 in their charting solutions while continuing to benefit from a mature, feature-rich chart control.

.netCHARTING is licensed per site (1 web site on 1 server), per server (unlimited web sites on 1 server) or per developer (single application) and is available as a perpetual license with a 12 month subscription which includes major and minor upgrades and priority email support.

スタンプを使ってPDFレビューを標準化

2月 17, 2026
組み込みまたはカスタムのスタンプ注釈を用いて、承認やワークフローに一貫した視覚的インジケーターを提供

Stamp annotation support in a PDF Viewer component allows applications to place predefined or custom visual marks, such as “Approved,” “Draft,” or date-based stamps, directly onto PDF pages as non-destructive annotations. For software developers, this capability simplifies the implementation of document review and approval processes by enabling users to apply consistent, repeatable markings without altering the underlying content. It improves traceability and collaboration by making document status and actions immediately visible, supports automation through programmatic stamp placement, and helps maintain document integrity while meeting common business and compliance requirements.

Several .NET PDF viewer components support stamp annotations, including:

  • Document Solutions for PDF by MESCIUS lets you add stamp annotations, in the PDF Viewer, to indicate status without content changes.
  • XFINIUM.PDF CROSS PLATFORM EDITION allows you to place predefined and custom stamp annotations, through its PDF Viewer, for clear review and approval marking.
  • PDFView4NET Windows Forms Edition by PDF4DEV Solutions facilitates applying stamp annotations, helping applications visually communicate decisions without altering files.
  • Syncfusion ASP.NET Core PDF Viewer (part of Syncfusion Essential Studio Enterprise) allows you to implement stamp annotation support, enabling consistent status indicators.

効率的なLINQプロジェクションでデータアクセスを最適化

2月 17, 2026
AutoMapperは、規約と検証を用いてオブジェクトマッピングを改善し、ボイラープレートコードの削減と.NET開発の加速を実現

AutoMapper by Lucky Penny Software is a convention-based object-to-object mapping library designed for Microsoft .NET developers. It improves the process of transforming data between objects, particularly when mapping complex domain models to simpler Data Transfer Objects (DTOs), using intelligent conventions and configuration options to minimize manual coding.

By eliminating repetitive boilerplate mapping code, AutoMapper helps developers build cleaner, more maintainable applications. It enforces consistent naming conventions, validates mappings at runtime, and optimizes LINQ projections for efficient data querying. This makes it especially valuable in layered architectures, API development, and enterprise applications where data transformation is frequent and complex. From startups to large organizations, teams use AutoMapper to reduce errors, accelerate development cycles, and focus on delivering business value rather than managing tedious object-mapping logic.

AutoMapper is licensed on an annual subscription basis per development team, with Standard (1–10 developers), Professional (11–50 developers), and Enterprise (unlimited developers) tiers. See our AutoMapper licensing page for full details.

ストリームからの安全なPDF読み込みを有効化

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:
