PDF Xpansion SDK v17.2.7 添加对 ZUGFeRD 2.4 的支持，有助于开发人员保持按照当前欧洲标准开具电子发票合规。

PDF Xpansion SDK E-Invoicing by soft Xpansion is a comprehensive software development kit for creating, processing, and managing electronic invoices in compliance with international standards. It simplifies integration into existing applications and supports structured invoice data in XML as well as hybrid PDF/A formats, including common standards such as ZUGFeRD, Factur-X, and XRechnung. The SDK enables developers to create, edit, display, and extract data from compliant invoices, supporting automated digital invoicing workflows, legal conformity, and straightforward connection with accounting or enterprise resource planning (ERP) systems.

The PDF Xpansion SDK v17.2.7 update adds support for ZUGFeRD 2.4, allowing applications to generate and process e-invoicing documents that align with the latest version of the German and European e-invoicing standard based on EN 16931 (European Norm 16931). For software developers, this support ensures continued compatibility with evolving regulatory requirements, improves interoperability with trading partners and public sector systems, and reduces the risk of invoice rejection caused by outdated schemas or validation rules. By targeting ZUGFeRD 2.4, applications built on the SDK can handle current e-invoicing profiles with greater reliability while remaining suitable for long-term maintenance in compliance-focused environments.

To see a full list of what's new in v17.2.7, see our release notes for PDF Xpansion SDK E-Invoicing Creation, Receipt or Receipt Plus.

PDF Xpansion SDK E-Invoicing is available in 3 variations, licensed per company location where developers use the SDKs. Optional Add-Ons are available which require ownership of SDK site licenses. Maintenance Subscription is available providing product updates (error corrections) and 12 man hours of support service for 1 year. See the product license pages for full details:

在 WPF 数据网格中输入非拉丁字母

对输入法编辑器（IME）的支持允许 WPF 应用程序直接在可编辑的网格组件中处理复杂脚本的文本输入。

Input Method Editor (IME) support refers to the capability of an application or control to correctly handle complex text input, particularly for languages that require composition, such as Chinese, Japanese, and Korean. IME enables users to enter characters that are not directly available on a physical keyboard by converting sequences of keystrokes into the correct script, improving accessibility and usability for multilingual input. When applied to a data grid within an application, this capability ensures that users can reliably enter and edit multilingual text directly within grid cells without input loss or formatting issues. IME support in a data grid is especially valuable for applications that manage structured data across regions, as it allows accurate entry of names, descriptions, and other localized content while preserving normal grid behaviors such as editing, validation, and navigation.

Several WPF grid components include Input Method Editor support, including:

  • DevExpress WPF Data Grid (part of DevExpress WPF) supports multilingual input in grid cells, allowing users to enter complex characters as needed.
  • ComponentOne WPF FlexGrid (part of ComponentOne Studio WPF by MESCIUS) accommodates composed character entry for languages requiring input composition.
  • Infragistics Ultimate UI for WPF Data Grid (part of Infragistics Ultimate UI for WPF) facilitates complex script input within grid cells for multilingual data entry.

在 WPF 中组织复杂的用户界面

1月 19, 2026
利用带有对接功能的 UI 套件，让用户控制 WPF 应用中的布局排列、浮动面板和持久工作区。

Docking controls are a key element of user interface design that enhance the usability of complex applications. They allow users to rearrange windows or panels within the main application window, making it easier to create personalized, efficient layouts. These controls typically support drag-and-drop interactions and automatic alignment, which help users maintain a tidy and organized workspace while working with multiple tools or data views. Docking frameworks often include features like tabbed documents, floating windows, and layout persistence, all of which contribute to a more flexible and user-driven application environment. This makes docking especially useful in professional software environments that involve large volumes of information or tool-based workflows.

Several WPF UI suites provide you with docking support, including:

  • DevExpress WPF offers a comprehensive docking system with advanced layout persistence, tabbed document interfaces, and runtime customization.
  • ComponentOne Studio WPF by MESCIUS provides a docking control that supports auto-hide, floating windows, and full integration with its theme and layout systems.
  • Telerik UI for WPF supports dockable and floatable panes, tabbed documents, nested docking, layout saving/loading, and other docking behaviors suitable for complex UIs.
  • Infragistics Ultimate UI for WPF features a flexible docking framework with rich layout options, including nested panes and content serialization for saving and restoring layouts.

DevExpress Universal 25.2 新增一个 API，允许应用程序在运行时解读用户意图并直接对 UI 组件和逻辑进行更改。

DevExpress Universal is a comprehensive suite of UI components and developer tools that supports the creation of feature-rich applications across web, desktop, and mobile platforms, including .NET, JavaScript, Blazor, ASP.NET, WinForms, WPF, and MAUI. It focuses on delivering consistent user interfaces, advanced data visualization, reporting, dashboards, and productivity features that help teams design, build, and maintain complex applications using a unified set of technologies and patterns.

DevExpress Universal v25.2 introduces AI Tool Calling (Natural Language Control for UI Components), a cross-platform feature that extends Microsoft.Extensions.AI tool-calling to enable natural-language interaction with application UI and logic. Developers can expose UI components, ViewModels, and business services as AI-invokable tools, grouped into dynamic toolsets that adapt to the application’s current context. When users interact through the DevExpress AI Chat Control, the language model interprets their request, selects the appropriate tool, resolves the target instance, and executes the action in real time, making applications easier to use while giving developers full control over what the AI can see and do.

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