让范围输入更简单

5月 12, 2026
范围栏数据编辑器允许用户交互式定义最小和最大允许值，从而减少了在报表、仪表盘和表单中的手动录入。

A Range Trackbar in ASP.NET Core Data Editor controls is an interactive input component that lets users select a numeric range by moving two handles along a track, rather than typing minimum and maximum values into separate fields. This makes range-based data entry faster, clearer, and less error-prone, especially when the valid values are bounded, such as prices, dates, percentages, ratings, quantities, or performance thresholds. For developers, it provides a more intuitive way to capture structured range input while maintaining control over validation, step intervals, formatting, and default values. In real-world applications, a Range Trackbar can be used in product filters to select a price range, reporting dashboards to define a date or score interval, booking systems to choose acceptable time windows, analytics tools to adjust threshold limits, or administrative forms where users need to configure minimum and maximum values without manually entering exact numbers.

Many ASP.NET Core Assembly Data Editors collections contain Range Trackbar controls including:

  • DevExpress ASP.NET Core Data Editors (part of DevExpress ASP.NET & Blazor) let you add Range Trackbar inputs for selecting numeric intervals clearly within responsive data forms.
  • Telerik UI for ASP.NET Core Data Editors (part of Telerik UI for ASP.NET Core) allows you to present Range Trackbar selection for filters, thresholds, and configurable values.
  • Wisej.NET enables Range Trackbar-style range selection in ASP.NET Core applications, supporting selection within minimum and maximum values for business data entry.
  • Syncfusion ASP.NET Core Data Editors (part of Syncfusion Essential Studio Enterprise) facilitates Range Trackbar input for choosing minimum and maximum values.

更高效地管理 PDF 文档

5月 7, 2026
添加内置 PDF 操作工具，无需依赖外部软件即可合并、拆分、压缩和重组文档。

PDF manipulation allow applications to create, modify, and manage PDF documents programmatically or through integrated user interfaces. These features support a wide range of document workflows, from reorganizing pages to extracting information and optimizing file sizes. By incorporating PDF manipulation tools directly into applications, developers can support more efficient document processing without relying on external software.

Common features include:

  • Compressing PDFs which reduces file sizes to make documents easier to store, transfer, and share while maintaining acceptable visual quality.
  • Deleting pages from a PDF enables users to remove unnecessary or sensitive content from existing documents.
  • Adding pages to a PDF allows new pages to be inserted into documents to expand or reorganise content.
  • Merging PDFs combines multiple PDF files into a single document, simplifying document management and distribution.
  • Splitting PDFs separates a document into smaller files, helping users isolate sections or distribute content more efficiently.
  • Extracting content allows users to retrieve text, images, or other embedded information from PDFs for reuse, analysis, or indexing purposes.
  • Managing metadata provides tools for viewing and updating document properties such as author details, titles, keywords, and creation dates.

在保留公式、格式和参考动态的同时添加新行以保持电子表格准确一致。

Inserting rows in spreadsheet components enables users to expand and reorganize data dynamically within a worksheet. It supports common data management tasks such as adding new records, adjusting layouts, and maintaining structured datasets without disrupting existing content. By integrating row insertion directly through APIs, applications can offer a familiar and efficient spreadsheet experience for users working with tabular data.

Several ASP.NET Core spreadsheet controls offer support for inserting rows including:

提供预定义值列表，帮助用户快速选择有效条目，从而提高准确性并减少验证开销。

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.

从 PDF 中删除敏感数据

4月 20, 2026
在 ASP.NET Core 应用程序中实现 PDF 编辑，以保护敏感信息并防止访问机密数据。

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.
