Simplify PDF Export Setup with Permission Toggles

November 13, 2025
ActiveReports.NET v19.2 adds a new permissions configuration panel for Web Viewer PDF exports, enabling granular control of user interactions.

ActiveReports.NET from MESCIUS, is a comprehensive reporting solution for developers building applications in .NET. It helps you to design and deliver visually appealing reports through user-friendly designers and a wide range of controls. ActiveReports simplifies report creation and distribution with a versatile API, rich data source connectivity, and support for multiple export formats. This translates to increased developer productivity and improved end-user experience with powerful reporting functionalities within your .NET applications.

The ActiveReports.NET v19.2 update introduces configurable permissions for PDFs exported from Web Viewers, allowing developers to apply precise controls over how end users interact with generated documents. By enabling encryption and selecting permissions such as copying, printing, annotating, modifying, filling forms, and accessing content through assistive readers, developers can enforce security, compliance, and workflow requirements directly within the export process. This update optimizes permission management across the JS Viewer, Blazor Viewer, and ASP.NET WebViewer, providing a consistent and efficient way to govern document behavior without additional code or external tooling.

Ensure Accuracy with Built-In Data Validation

November 11, 2025
Maintain reliable spreadsheet data entry with built-in validation tools that prevent errors and preserve data integrity across shared workbooks.

Data validation in spreadsheets allows users to control what information can be entered into each cell, ensuring that data remains accurate and consistent across a workbook. By defining specific rules and restrictions, it helps prevent incorrect inputs and maintains the integrity of shared data. Users can provide guidance through prompts or drop-down lists, reducing the likelihood of errors and saving time on data correction. This feature is especially valuable in collaborative settings, such as managing budgets, tracking inventory, or collecting survey responses, where reliable data entry is essential for accurate analysis and reporting.

Several ASP .NET Core spreadsheet products offer data validation, including:

  • DevExpress ASP.NET Core Spreadsheet (part of DevExpress ASP.NET and Blazor) lets you control data accuracy by defining validation rules and guiding users with clear feedback.
  • Aspose.Cells for .NET allows you to enforce consistent data entry by applying validation rules, dropdown lists, and custom error alerts.
  • Telerik ASP.NET Core Spreadsheet (part of DevExpress ASP.NET and Blazor) validates inputs, preventing errors, and maintaining consistent information across workbooks.
  • Syncfusion ASP.NET Core Spreadsheet (part of Syncfusion Essential Studio Spreadsheet Editor SDK) enables data entry through automatic prevention of invalid values.

Add Visible Notes Directly to Your PDFs

October 28, 2025
Free text annotations let developers embed persistent text into PDF pages, ideal for audits, reviews, or collaborative documentation.

Free text annotations in PDF-processing components enable users to place editable text directly onto document pages, enhancing notes, comments, or briefing elements without relying on external tools. This feature supports adding visible text blocks (rather than hidden pop-ups) that remain part of the document's content layer, allowing for richer, in-context feedback and markup across workflows such as review, auditing, or collaborative editing.

Several ASP.NET Core PDF controls offer support for free text annotations including:

  • Telerik UI PDF for ASP.NET Core (part of Telerik UI for ASP.NET Core) lets developers add customizable free text annotations to PDFs, with control over font, position, and more.
  • Document Solutions for PDF by MESCIUS provides a FreeTextAnnotation class that enables developers to place persistent text directly into a PDF, with properties for customization.
  • ImageGear for .NET by Accusoft supports FreeText via its ART marks API, allowing the creation of text annotations on PDFs and exporting them as FreeText annotation objects.

Transform How Users Interact with PDFs

October 23, 2025
Built-in editing tools let users compress, rearrange, merge, or split documents, making PDF viewers more useful for real-world workflows.

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.
