在自动更新单元格引用并保留现有计算的同时,在工作表任意处轻松添加新列。

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.

Lucky Penny Software 加入 ComponentSource

ComponentSource 与 Lucky Penny Software 合作,提供经过验证的 .NET 库,简化对象映射和应用消息传递。

Lucky Penny Software is a software company based in Austin, Texas, USA, focused on delivering high-quality libraries for the Microsoft .NET ecosystem. Its flagship products, AutoMapper and MediatR, are widely used by developers building modern applications. Originally created as free, open-source projects by founder Jimmy Bogard, creator of Vertical Slice Architecture, both libraries achieved broad adoption, with more than a billion downloads combined. They have since evolved into commercial offerings to ensure sustainable development, professional support, and continued innovation aligned with customer needs.

Lucky Penny Software's product offering includes AutoMapper, a convention-based object mapping library designed to simplify the transformation of complex domain models and Language Integrated Query (LINQ) results into clean Data Transfer Objects (DTOs). By applying consistent naming conventions and reducing the need for repetitive mapping code, it helps teams maintain clearer separation between layers while improving code readability and reliability. Built-in configuration validation further supports robust application design by identifying mapping issues early in the development process.

MediatR implements the mediator and command dispatcher patterns to support scalable application architectures. It provides an in-process messaging framework that routes requests and notifications to the appropriate handlers, reducing tight coupling between components. This approach aligns with Clean Architecture and Vertical Slice Architecture principles, enabling teams to build applications that are easier to test, extend, and maintain over time.

Through its partnership with Lucky Penny Software, ComponentSource adds these proven .NET libraries to its global software marketplace. This collaboration gives organizations a straightforward way to license and manage AutoMapper and MediatR within established procurement processes. Customers benefit from reliable access to commercial licensing, centralized purchasing, and dedicated support, while continuing to build applications on widely adopted architectural patterns and trusted development tools.

通过扁平化字段锁定 PDF 表单

启用 WinForms 应用将 PDF 文档中的表单字段扁平化,从而将用户输入转换为无法修改的静态页面内容。

Flattening form fields is the process of converting interactive PDF form elements into static content within the document. Once flattened, the data entered into fields becomes part of the page itself, preventing further editing or manipulation. This ensures that the document can be viewed consistently across devices and PDF readers, while preserving the integrity of the submitted information. It is particularly valuable for finalized contracts, reports, and compliance documents where maintaining an accurate, unalterable record is essential.

Several WinForms PDF components allow you to flatten form fields, including:

  • Telerik UI for WinForms PdfProcessing (part of Telerik UI for WinForms) supports programmatic flattening of AcroForm fields so forms can be locked with preserved layout.
  • ImageGear for .NET by Accusoft provides APIs to convert form fields into static page content, removing interactivity and preserving entered data.
  • XFINIUM.PDF WINDOWS/MAC EDITION enables form fields to be flattened during processing, embedding field values into the document content.
  • Syncfusion WinForms PDF (part of Syncfusion Essential Studio Document SDK) allows developers to flatten individual fields or entire forms to prevent editing before sharing.

在 .NET 消息控件中支持国际字符集可在全局系统间传输时保持文本完整性。

International Character Sets support in .NET communications controls refers to the ability of networking and messaging components to correctly transmit, receive, and process text data encoded in various global character standards, such as Unicode, UTF-8, UTF-16, and legacy code pages. This capability ensures that applications can reliably handle multilingual content, including non-Latin scripts, accented characters, symbols, and right-to-left languages, without data corruption or misinterpretation during serialization, transport, or display. By supporting standardized encoding mechanisms, .NET communications controls allow developers to build globally compatible services, APIs, email clients, and messaging systems that maintain text integrity across different platforms, operating systems, and regional settings, which is essential for modern distributed and internationalized applications.

Several .NET communications and messaging components offer support for international character sets including:

  • MailBee.NET POP3 by AfterLogic allows you to retrieve and process multilingual email messages using Unicode and varied international encodings reliably.
  • PowerTCP Mail for .NET by Dart Communications lets you send, receive, and parse global email content with comprehensive character encoding compatibility.
  • Rebex Mail Pack enables sending and receiving multilingual email content with full Unicode, MIME, and international header encoding support.
  • SocketTools .NET Edition by Catalyst Development Corp. supports transmitting multilingual data using Unicode, UTF-8, configurable code pages, and MIME encoding.

将一张或多张图片转换为单一高质量 PDF,便于分享、打印、安全,并且跨设备和平台使用一致。

Image-to-PDF conversion transforms one or more image files into a single, standardized PDF document, maintaining image quality and consistent layout. Converting images to PDF improves accessibility across devices and platforms, simplifies sharing and printing, and helps organize multiple images into one professional file. It also supports features such as compression and security, making documents easier to store and protect. Common use cases include compiling scanned documents or receipts, creating reports from images, and sharing visual records in a reliable, universally supported format.

Several .NET PDF components allow you to convert images to PDF, including:

  • Aspose.PDF for .NET lets you convert images into high-quality PDFs programmatically, preserving layout, resolution, and security within .NET applications.
  • ComponentOne WinForms PDF (part of ComponentOne Studio WinForms by MESCIUS) allows you to combine images into PDFs with precise control over layout and compression.
  • IronPDF for .NET facilitates image-to-PDF conversion with simple APIs, enabling fast document creation, customization, and secure distribution in applications.
  • GroupDocs.Conversion for .NET lets you transform images into PDFs at scale, supporting batch processing, consistent formatting, and flexible integration scenarios.
