構造化されたツリーベースのナビゲーションを提供し、ユーザーが関連するセクションに直接ジャンプし、文書とより効率的にやり取り可能

Bookmark navigation in a PDF Viewer enables developers to expose the hierarchical bookmark structure embedded within a PDF so users can quickly jump to specific sections or pages. It typically presents bookmarks in a tree view synchronized with the document, allowing programmatic control and event handling for selection changes. This capability improves usability in applications that handle large or structured documents by reducing manual scrolling, supporting faster content discovery, and providing a more organized reading experience.

インタラクティブなグリッドリンクは関連コンテンツへのナビゲーションを可能にし、ユーザー体験を向上させ、生産性を高め、情報へのアクセスを支援

Hyperlinks in grids allow individual cells to function as clickable links, enabling users to navigate directly to related records, pages, or external resources. This makes data more interactive and improves usability by reducing manual searching. Users can quickly access additional context such as detailed views, reports, or linked systems without leaving the grid. Common use cases include linking customer names to profiles, order IDs to transaction details, or connecting data to external documentation, helping improve productivity and efficiency.

Several .NET WinForms grid controls offer hyperlink cell types, including:

  • Telerik UI for WinForms GridView (part of Telerik UI for WinForms) lets you embed hyperlinks in cells to enable navigation to related records and resources.
  • ComponentOne WinForms FlexGrid (part of ComponentOne Studio WinForms by MESCIUS) allows you to incorporate hyperlink cells that enable navigation to related data.
  • Syncfusion WinForms DataGrid (part of Syncfusion Essential Studio Enterprise) facilitates clickable hyperlinks within cells, helping users access related data without leaving context.
  • Bunifu UI WinForms allows you to design grids with hyperlink enabled cells, providing intuitive navigation and enhancing user interaction efficiency.

Dropdowns and lists provide structured ways for users to select and manage values within grids, forms, or tables. By constraining input to predefined options, these controls help maintain data consistency, reduce entry errors, and improve overall usability. They are commonly used in business applications where accuracy and efficiency are important, such as configuration panels, data management tools, and enterprise systems.

Common features include:

  • Combobox combines text input with a dropdown list, allowing users to either select from predefined values or enter custom data.
  • Checked Combobox extends this by enabling multiple selections through checkboxes within the dropdown.
  • Image Combobox enhances visual recognition by displaying icons or images alongside each option.
  • Listbox presents a scrollable list of items for single or multiple selection within a fixed area.
  • Checked Listbox adds checkbox support to allow users to select multiple items more clearly.
  • Image Listbox incorporates images into list items, helping users quickly identify and differentiate between options.

ASP.NET CoreアプリケーションでPDF編集機能を実装し、機密情報を保護し、機密データへのアクセスを防止

PDF redaction is the process of permanently removing sensitive or confidential information from a document so that it cannot be recovered or viewed. Unlike simple visual masking, true redaction deletes the underlying content, ensuring it is not accessible through copying, searching, or metadata extraction. This capability is essential for regulatory compliance, data protection, and secure document sharing, particularly in industries that handle personal, financial, or legal information.

Several ASP.NET Core PDF components allow you to redact PDFs, including:

  • Document Solutions for PDF by MESCIUS provides a .NET API that enables developers to define and apply redaction regions and permanently remove sensitive content from PDFs.
  • ImageGear for .NET by Accusoft includes redaction annotations allowing applications to mark and obscure confidential information within documents.
  • Syncfusion ASP.NET Core PDF (part of Syncfusion Essential Studio Enterprise) offers redaction support, with APIs to mark and remove sensitive text or images.
