Capture PDF Content Through the Viewer

December 30, 2025
Enable apps to extract user-selected text and regions directly from PDF documents, aligning retrieved data with visible on-screen interactions.

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.

Restructure PDFs in Desktop Applications

December 24, 2025
Change page sequence to improve document structure, support compliance needs, and manage complex PDFs more efficiently.

Moving pages in a PDF file refers to the ability to change the order of individual pages within the document. This is typically done by dragging and dropping pages into a new sequence or by specifying where a page should be relocated. The main benefit of this feature is improved document organization, especially in cases where content needs to be restructured for clarity, relevance, or compliance with formatting requirements. It also simplifies tasks such as compiling reports, merging multiple sources, or preparing documents for printing and distribution, making it easier to manage large or complex PDF files efficiently.

Several WPF PDF components allow you to move pages in a PDF, including:

  • Telerik UI for WPF PdfProcessing (part of Telerik UI for WPF) lets you reorder PDF pages programmatically, enabling the dynamic restructuring of documents in WPF apps.
  • IronPDF for .NET by Iron Software allows you to reposition pages inside PDFs via code, helping developers customize document flow and prepare files for output or review.
  • XFINIUM.PDF WPF/UWP EDITION enables page movement within PDFs, giving UWP and WPF applications precise control over document layout and sequence adjustments.
  • Syncfusion WPF PDF (part of Syncfusion Essential Studio Enterprise) lets you reorder pages in PDF files through its API, supporting document editing and structured presentation.

Enable PDF Annotation in WinForms Apps

December 19, 2025
PDF viewers with built-in annotation tools let users review, comment, and collaborate on documents without modifying the original content.

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.

Add Navigation to PDFs with Bookmarks

December 10, 2025
.NET PDF components with bookmark navigation let users quickly jump to specific content in complex, multi-page documents.

Bookmark navigation in a .NET PDF control allows users to access and move through predefined sections within a PDF document using a hierarchical list of bookmarks. While commonly used for chapters, bookmarks can also point to tables, figures, appendices, or any specific content, enabling flexible navigation across various elements of a document. Developers can create bookmarks dynamically based on document structure, metadata, or application logic, making it easier to guide users through complex content or highlight specific areas of interest.

Several .NET PDF components offer bookmark navigation including:

  • DevExpress PDF Document API for .NET (part of DevExpress Office File API) allows developers to programmatically add, edit, and remove bookmarks in PDFs.
  • Document Solutions for PDF by MESCIUS enables .NET apps to manage bookmarks so users can jump directly to pages, sections, or content elements in complex PDFs.
  • Aspose.PDF for .NET allows insertion and manipulation of PDF bookmarks so users can navigate to sections, headings, or customized targets efficiently.
  • Telerik UI for WPF PdfProcessing (part of Telerik UI for WPF) supports bookmarks in PDF documents, enabling hierarchical navigation inside .NET applications.
