Enable Secure PDF Loading from Streams

February 16, 2026
Load and render PDFs directly from streams for secure, file-free viewing across cloud, container, and database-driven ASP.NET applications.

Opening PDFs directly from streams in ASP.NET PDF Viewer components refers to the ability to load and render PDF documents from a .NET Stream object rather than from a physical file stored on the server. This means the PDF content can be retrieved dynamically from sources such as databases, cloud storage, web APIs, or generated in memory at runtime, and then passed directly to the viewer for display. By working with streams, applications can avoid temporary file storage, improve security by reducing file system exposure, and better support modern deployment scenarios such as containerized or cloud-based environments where local storage may be limited or transient.

Several ASP.NET Core PDF viewer components offer open PDFs from stream functionality including:

Insert Columns Without Breaking Formulas

February 12, 2026
Easily add new columns anywhere in a worksheet while automatically updating cell references and preserving existing calculations.

Inserting columns in a spreadsheet allows users to expand worksheets dynamically while preserving existing data and formulas. This capability is essential for scenarios where datasets evolve over time, such as adding new fields, categories, or calculated values. A well-implemented insert columns feature ensures that cell references, formatting, and formulas adjust automatically, helping maintain data integrity and reducing the risk of errors during updates.

Several ASP.NET Core spreadsheet controls offer the ability to insert columns including:

  • DevExpress ASP.NET Core Spreadsheet (part of DevExpress ASP.NET and Blazor) enables users to insert one or multiple columns at any position in a worksheet, automatically updating formulas.
  • Telerik UI for ASP.NET Core Spreadsheet (part of Telerik UI for ASP.NET Core) allows columns to be inserted through both the user interface and APIs, ensuring that cell references are preserved.
  • Syncfusion ASP.NET Core Spreadsheet (part of Syncfusion Essential Studio Enterprise) provides options to insert columns with full support for formula recalculation.

January 27, 2026
Enable faster data capture and improved traceability by embedding machine-readable barcodes into printed or digital reports.

Adding barcodes to reports means embedding machine-readable codes that represent key data such as IDs, records, or transaction details, allowing information to be scanned and processed instantly. This enhances efficiency by reducing manual data entry, improving accuracy, and enabling integration with backend systems like inventory management, ERP, or tracking platforms. Barcodes in reports also support automation and traceability, making it easier to identify, validate, and track documents or items throughout a process. Common use cases include inventory and asset tracking, order fulfillment and shipping documentation, patient and sample identification in healthcare, financial and compliance reporting, and any scenario where fast, reliable data capture from printed or digital reports is essential.

Several ASP.NET Core reporting controls offer barcode support including:

  • DevExpress Reporting lets you embed dynamic barcodes in reports to enable accurate scanning, automated processing, and data integration processes.
  • Telerik Reporting allows you to generate barcode-enabled reports that support fast identification, reliable tracking, and efficient system interoperability across organizations.
