用直观的分组和筛选工具轻松组织、浏览和分析数据，这些工具可在电子表格中创建可折叠的大纲。

Grouping and filtering are key spreadsheet tools that make data easier to manage and analyze. Grouping combines related rows or columns into collapsible sections for clearer summaries. Filtering displays only the information that meets specific conditions, helping focus on what matters most. Together, these features improve data management, reduce visual clutter, and enhance analytical clarity.

Several .NET WinForms spreadsheet controls contain data filtering and grouping controls including:

  • DevExpress WinForms Spreadsheet (part of DevExpress WinForms) lets you efficiently organize and analyze large datasets by grouping and filtering data.
  • Spread.NET WinForms (part of Spread.NET by MESCIUS) allows you to manage complex spreadsheets with intuitive grouping and advanced filtering for focused data analysis.
  • Infragistics WinForms Spreadsheet (part of Infragistics Ultimate UI for Windows Forms) facilitates data exploration through grouping and precise filtering.
  • MindFusion.Spreadsheet for WinForms enables streamlined data management with collapsible grouping and targeted filtering to simplify data review.

改变用户与 PDF 交互的方式

10月 23, 2025
内置编辑工具让用户压缩、重新排列、合并或拆分文档，使 PDF 查看器对实际工作流程更有用。

PDF manipulation features in viewer components extend the user experience beyond reading by enabling real-time structural changes to documents. These capabilities are particularly valuable in document-heavy workflows, where users need to rearrange, combine, or refine content without switching between multiple tools. Whether integrated into web portals, business systems, or productivity applications, built-in manipulation functions make PDF viewers more interactive and practical for day-to-day tasks such as document assembly, editing, and cleanup.

Common features include:

  • Adding pages to a PDF allows inserting new pages from blank templates or external files, supporting document expansion or correction.
  • Compressing PDFs reduces file size while preserving quality, making PDFs easier to store, send, and load - especially in web-based environments.
  • Deleting pages from a PDF enables users to remove unwanted or redundant pages, helping streamline documents before sharing or archiving.
  • Extracting pages from a PDF means selected pages can be isolated and saved as a new document, useful for creating summaries or sharing specific sections.
  • Merging PDFs combines multiple files into a single document, ideal for bundling reports, contracts, or records.
  • Moving pages in a PDF allows users to reorder pages via drag-and-drop interfaces or APIs, tailoring document structure without external tools.
  • Splitting PDFs enables large documents to be divided into smaller files based on page ranges or sections, simplifying distribution or version control.
