优化 .NET 项目中的网格显示

1月 6, 2026
列跨度均匀分配空间，使 .NET 网格能够干净地适应任何容器宽度，无需手动调整大小。

Data grids with column spanning functionality can be configured so the columns collectively extend to fill the entire width of the container, eliminating unused or empty space at the grid's edges. This behavior ensures that available horizontal space is distributed across columns rather than leaving fixed-width gaps, resulting in a more balanced and visually consistent layout. The primary benefits are improved readability, more efficient use of screen space, and a layout that adapts smoothly to resizing and different display sizes without requiring manual adjustment of individual column widths.

Several .NET grid components allow column spanning, including:

  • DevExpress WinForms Data Grid (part of DevExpress WinForms) allows columns to stretch across the container width, eliminating edge whitespace automatically.
  • ComponentOne .NET MAUI FlexGrid (part of ComponentOne WinUI and MAUI Edition by MESCIUS) distributes column widths to fully occupy available container space responsively.
  • Xceed DataGrid for WPF by Xceed Software facilitates automatic column width stretching so grids fill their containers without leaving unused margins during resizing.
  • Blazorise allows you to build grid layouts where columns expand to fill container width, ensuring consistent spacing responsively across devices.

快速将 Word 文档转换为 PDF

用可靠的 Word 到 PDF 转换创建专业的可打印 PDF，该转换可保持格式并能跨设备显示一致。

Converting Word to PDF involves transforming DOC or DOCX documents into a fixed, universally supported format that preserves formatting, layout, fonts, and images. This process ensures documents display consistently across different devices, operating systems, and applications, regardless of whether the recipient has Microsoft Word installed. By reducing the risk of unintended edits and layout changes, PDF output provides a more secure and professional way to share finalized content. Typical use cases include distributing reports, proposals, and contracts, preparing documents for printing, sharing files with external stakeholders, and archiving important records for long-term storage or compliance purposes.

Several .NET components offer Word to PDF conversion including:

  • DevExpress PDF Document API for .NET (part of DevExpress Office File API) lets you convert Word documents to PDFs while preserving layout, fonts, consistency accurately.
  • ImageGear for .NET lets you convert Word files into PDFs optimized for viewing, printing, archiving, and long-term document preservation needs.
  • GroupDocs.Conversion for .NET facilitates Word to PDF conversion, maintaining document structure, visual accuracy, and cross-device compatibility.
  • IronPDF for .NET allows you to transform DOC and DOCX files into reliable PDFs with consistent formatting across platforms.

通过查看器捕获 PDF 内容

12月 30, 2025
使应用能够直接从 PDF 文档中提取用户选择的文本和区域，从而将检索到的数据与屏幕上可见的交互对齐。

Extracting content using a PDF Viewer refers to enabling end users or applications to select and retrieve content directly through the viewer’s user interface, based on interactive actions such as text selection, area selection, or page-level capture. For software developers, this means the viewer acts not only as a rendering surface but also as a controlled extraction layer that exposes selected text, images, or regions. This approach is valuable in review, approval, and data capture scenarios because it reflects explicit user intent, aligns extracted data with what is visibly selected on screen, and avoids reliance on background parsing alone, resulting in more predictable and user-driven content retrieval within applications.

Several WinForms PDF Viewer components allow content extraction, including:

  • DevExpress WinForms PDF Viewer (part of DevExpress WinForms) allows you to extract user-selected text and visual regions directly through the PDF viewer.
  • Telerik UI for WinForms PDF Viewer (part of Telerik UI for WinForms) allows you to capture visually selected PDF content in the viewer, returning text aligned with user interactions.
  • PDFView4NET Windows Forms Edition by PDF4DEV Solutions facilitates extracting text, images, and regions directly from its PDF viewer based on  user selections.
  • Syncfusion WinForms PDF Viewer (part of Syncfusion Essential Studio Enterprise) lets you retrieve user-selected PDF text and areas via the viewer.

DevExpress WinForms 25.2 允许您轻松切换 AI 服务，并且无需离开您的应用即可比较其输出。

DevExpress WinForms is a comprehensive suite of 190+ UI controls and development tools designed for building high-performance desktop applications.

This empowers developers to rapidly create functionally rich applications, while adhering to accessibility guidelines and touch-enabled technology for modern Windows environments.

The DevExpress WinForms 25.2 update introduces multi-provider support in the AI Chat Control, allowing developers to integrate several AI services into one application. This enables advanced use cases such as side-by-side comparison of responses from different AI models, concurrent sessions with independent chat histories, and dynamic switching between providers during runtime. It’s especially useful in environments where evaluating model performance or offering user choice is essential, such as customer support tools, research platforms, or development sandboxes.

To see a full list of what's new in version 25.2, see our release notes.

ComponentOne Studio WinForms 2025 v2 通过侧对齐标签增强了 FlexPie，使视觉更清晰，可读性更佳。

ComponentOne Studio WinForms by MESCIUS is a comprehensive toolkit offering over 120 advanced UI components to improve Windows Forms application development. It helps you to build visually appealing and feature-rich applications with functionalities like data visualization through charts and reports, intuitive data editing with performant grids, and modern UI elements including ribbons and docking for a user-friendly experience.

The ComponentOne Studio WinForms 2025 v2 update introduces a new data label placement option for FlexPie that aligns labels along the left and right sides of the chart to improve readability and visual structure. By moving labels out of the pie area, this option reduces overlap and congestion when working with datasets that contain many slices or small values, which are common challenges in pie chart rendering. The result is a more consistent and predictable layout that helps developers present data more clearly while maintaining a clean, modern appearance across different screen sizes and data scenarios.

To see a full list of what's new in 2025 v2, see our release notes.

ComponentOne Studio WinForms is licensed per developer on a perpetual basis and includes a 12 month subscription. Priority Support is also available. See our ComponentOne Studio WinForms licensing page for full details.
