.netCHARTING 10.8 為最新的 .NET 平臺配置了其資料視覺化引擎，從而確保開發人員能構建新式圖表解決方案。

.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.

用印章標準化 PDF 審核

使用內置或自訂印章注釋為審批和工作流程提供一致的視覺指示。

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.

用高效的 LINQ 投影優化資料存取

AutoMapper 透過約定和驗證改進了物件映射，從而減少了樣板代碼並加快了 .NET 開發。

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.

啟用從流載入安全 PDF

直接從流載入和渲染 PDF，實現跨雲端、容器和資料庫驅動 ASP.NET 應用的安全、無文件流覽。

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:

DevExpress Office File API 添加對 PowerPoint 表格的支援，使應用程式能夠在簡報檔中讀取、寫入和修改表格資料。

DevExpress Office File API is a robust library designed to simplify the creation, editing, and processing of popular office document formats, including Word, Excel, PowerPoint, and PDF. It allows developers to integrate advanced document management features into their applications without relying on external software like Microsoft Office. Key features include document generation, data import/export and template customization. The API supports advanced formatting, encryption, and digital signatures, ensuring secure and professional-grade output.

The DevExpress Office File API now includes full support for PowerPoint tables, allowing applications to upload and save presentations that contain tabular data and interact with that data through code. Developers can read existing tables, modify their structure and content, remove tables that are no longer needed, or create entirely new tables from scratch. This addition makes it easier to automate report generation, update presentation data, and integrate PowerPoint files into document processing workflows where tables play a central role.

DevExpress Office File API is licensed per developer and is available as a Perpetual License with a 12 month support and maintenance subscription. See our DevExpress Office File API licensing page for full details.

DevExpress Office File API is available individually or as part of DevExpress Universal.
