在 .NET 應用程式中將報表綁定到 IList

1月 6, 2026
使用記憶體中的 .NET 集合作為直接資料來源，在運行時構建靈活且無資料庫的報表。

IList data source support in .NET Reporting components allows developers to bind reports directly to in-memory collections that implement the IList interface, such as generic lists or arrays. This capability offers flexibility for working with dynamically generated data or data not stored in a traditional database, making it easier to integrate with object-oriented models. It reduces the need for intermediary storage, supports runtime data manipulation, and is particularly effective in applications where data is constructed or retrieved at runtime through APIs rather than direct database access.

Several .NET Reporting controls offer IList data connectivity including:

  • DevExpress Reporting lets you connect reports to IList-based collections, enabling flexible in-memory data binding without requiring a database layer.
  • ActiveReports.NET Professional by MESCIUS allows you to use IList objects as data sources, supporting direct reporting from application-level collections.
  • Telerik Reporting facilitates binding to IList implementations, making it easy to report on dynamically generated or API-fetched in-memory data.
  • List & Label Professional Reporting Edition by combit supports IList data sources, allowing efficient report generation from structured objects or arrays within your application.

用內建樞紐分析表總結資料集

1月 6, 2026
Spread.NET v19 添加樞紐分析表引擎，讓使用者直接在試算表內總結、分析和探索大型資料集。

Spread.NET by MESCIUS is a tool for building Excel-like applications in your .NET projects. It lets you create interactive spreadsheets, grids, dashboards, and even forms within WinForms, ASP.NET, and WPF applications. With its rich feature set, including a robust calculation engine, formula support, and Excel compatibility, Spread.NET helps developers to build data analysis tools, budgeting apps, scientific dashboards, and more, all within the familiar .NET environment.

The Spread.NET v19 update introduces a new pivot table engine that enables software developers to summarize, analyze, and explore large datasets directly within WinForms applications. This built-in capability supports interactive grouping, filtering, and multidimensional analysis inside the spreadsheet, allowing users to work with complex data without exporting it to external reporting or business intelligence tools. By delivering Excel-like pivot table functionality with high performance and programmatic control, the pivot engine helps developers simplify application architecture, reduce dependencies, and provide a more integrated and responsive data analysis experience for end users.

To see a full list of what's new in v19, see our release notes.

Spread.NET is licensed per developer and is available as a Perpetual License with a 12 month support and maintenance subscription. We can supply any Spread.NET license including new licenses, maintenance renewals, and upgrade licenses. See our Spread.NET licensing page for full details.

優化 .NET 專案中的網格顯示

1月 6, 2026
欄位跨度均勻分配空間，使 .NET 網格能夠乾淨地適應任何容器寬度，無需手動調整大小。

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.

快速將 Word 文件轉換成 PDF

用可靠的 Word 到 PDF 轉換創建專業的可列印 PDF，該轉換可保持格式並能跨設備顯示一致。

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.

透過檢視器擷取 PDF 內容

12月 30, 2025
使應用能夠直接從 PDF 文件中提取使用者選擇的文本和區域，從而將檢索到的資料與螢幕上可見的交互對齊。

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.
