ComponentOne Studio Enterprise 2025 v2 提供了 .NET 10 WPF 新式運算式編輯器，讓使用者能夠輕鬆構建準確的運行時公式。

ComponentOne Studio Enterprise is a comprehensive suite of .NET UI controls developed by MESCIUS (formerly GrapeCity) designed for building rich, interactive desktop, web, and mobile applications. It provides developers with a broad range of tools and components-including data grids, charts, reports, input controls, and advanced data visualization features-for platforms such as WinForms, WPF, ASP.NET Core, Blazor, WinUI, and .NET MAUI. The suite emphasizes performance, flexibility, and ease of integration, helping teams create consistent, feature-rich user experiences across multiple application types while maintaining a unified development approach.

The ComponentOne Studio Enterprise 2025 v2 update introduces a modern WPF ExpressionEditor that enables developers to integrate a complete runtime formula-building experience directly into their applications. It allows end users to create, edit, and validate logical expressions using familiar Visual Studio–style code completion, syntax highlighting, and real-time error reporting, while also providing a set of built-in operators, constants, and aggregate, logical, mathematical, and conversion functions. By offering both a lightweight expression text box and a full-featured formula panel, the update reduces the need for custom expression editors, shortens development time, and improves the reliability and usability of data-driven application logic.

在 WinForms 應用中啟用 PDF 注釋

12月 19, 2025
帶有內置注釋工具的 PDF 檢視器讓使用者在不修改原始內容的情況下審查、評論和協作文件。

PDF annotation in .NET WinForms PDF viewer components refers to the ability to add visual and textual markup directly onto PDF documents without altering the original content. These tools allow users to draw shapes, highlight text, insert comments, and place notes within the viewing interface, supporting workflows such as document review, feedback, and approval. This functionality improves collaboration and clarity in document handling, making it well-suited for document processing tasks in WinForms applications.

Common features include:

  • Freehand Draw (Ink Annotation) allows users to sketch, underline, or handwrite directly on the page using a mouse, stylus, or touch input, making it ideal for markups and signatures.
  • Lines provide a simple way to connect points or emphasize linear elements within a document, often with configurable thickness, color, and opacity.
  • Rectangles enable users to highlight or frame areas of interest, supporting both outlined and filled styles for visual emphasis.
  • Ellipses offer a similar highlighting function to rectangles but with a rounded shape, useful for circling content or marking irregular regions.
  • Arrows are commonly used to direct attention to specific content, combining line styling with arrowheads to clearly indicate focus or flow.
  • Sticky Note annotations allow users to attach comments to precise locations in the document, typically displayed as icons that reveal text on interaction.
  • Free Text enables direct placement of typed text onto the page with control over font, size, color, and alignment, supporting clear, visible commentary without pop-ups.

直接在 WPF 資料應用中輕鬆編輯圖片

在應用內啟用 WPF 圖片編輯功能，帶有注釋、裁剪、變換、縮放、撤銷和重做以及簡單的導入和匯出功能。

Image editing in a data editor component helps users work with images alongside other data fields. This includes basic functions like cropping, rotating, resizing, and adding annotations. It's useful for tasks such as cleaning up user-uploaded files, adjusting product photos, or marking up visual references—all without switching to another application. This keeps image handling part of the same process as your data updates.

Several .NET data editor collections provide an image editor, including:

  • DevExpress WPF Data Editors (part of DevExpress WPF) lets you embed image editing within forms, enabling cropping, annotation and validation.
  • Telerik UI for WPF Data Editors (part of Telerik UI for WPF) allows you to integrate image modification tools into business apps, supporting annotations and transformations.
  • Syncfusion WPF Data Editors (part of Syncfusion Essential Studio Enterprise) facilitates image editing in data driven interfaces, enabling adjustments and visual annotations.
