查找和替换 JavaScript 电子表格中的数据

4月 29, 2025
为电子表格 Web 应用程序配备灵活且高级的查找和替换功能,从而简化更新内容的过程。

Find and replace functionality in a spreadsheet application enables users to quickly search for specific text, numbers, or characters within a worksheet and substitute them with alternative content. Often including advanced options such as case sensitivity, regular expressions, and the ability to target specific sheets or cell ranges, this feature lets users make consistent updates across large datasets without manually editing each cell. By automating these repetitive tasks, it reduces the risk of human error and significantly enhances productivity and accuracy in data processing. It is particularly useful for correcting errors, updating outdated information, or standardizing entries, such as changing all instances of an old product name to a new one.

Several JavaScript spreadsheet controls offer find and replace functionality, including:

  • SpreadJS by MESCIUS equips JavaScript developers with the ability to perform search and replace operations via a dialog, supporting advanced options like case matching.
  • Jspreadsheet Pro is a data grid with spreadsheet controls, providing JavaScript applications with find and replace functionality via an advanced search and replace extension.
  • Syncfusion Spreadsheet JavaScript (part of Syncfusion Essential Studio Enterprise) facilitates flexible find and replace capabilities to simplify targeted editing.

用密码保护来保护 PDF 文件

4月 25, 2025
通过使用密码控制用户访问和权限,以确保 PDF 文档中的数据机密性和完整性。

PDF password protection is a security feature that restricts access to the PDF file by requiring a password to open, modify, print or copy its contents. By setting either an open password (to prevent unauthorized viewing) or a permissions password (to control actions such as editing or printing), this mechanism ensures that document owners can safeguard sensitive information against unauthorized access or tampering. This is particularly useful in professional and legal contexts where data confidentiality and document integrity are critical, helping to maintain compliance with privacy standards and internal data protection policies.

Several JavaScript PDF components allow you to protect PDFs with passwords, including:

  • Wijmo PDF (part of Wijmo by MESCIUS) provides JavaScript components that allow you secure PDF files via password protection to restrict access and content manipulation.
  • Aspose.PDF for JavaScript via C++ enables you to implement user and master passwords programmatically for fine-grained control over who can view or manipulate PDF content.
  • IronPDF for Node.js by Iron Software equips JavaScript-based web applications with the ability to protect PDFs with passwords to ensure confidentiality and controlled user access.

Telerik Reporting 2025 Q1 为 Blazor 和 Angular 引入了用户触发的报表预览,从而提高了渲染效率。

Telerik Reporting is a comprehensive and lightweight embedded reporting tool for .NET web and desktop applications. It enables developers and reporting users to create, design, and export visually appealing, interactive, and reusable reports to effectively present analytical and business data. It supports various technologies, including ASP.NET Core, Blazor, ASP.NET MVC, ASP.NET AJAX, HTML5/JS, Angular, WPF, WinForms, and WinUI.

The Telerik Reporting 2025 Q1 update introduces user-initiated initial report preview in the native Blazor and Angular viewers, giving developers greater control over how and when reports are rendered. Instead of automatically generating reports on viewer load, this feature allows end users to manually trigger the preview process. This improvement helps reduce unnecessary data processing and improves application performance, particularly in scenarios involving large datasets or complex report logic. It also supports more efficient resource management on both the client and server sides, enabling developers to create faster, more responsive, and user-friendly reporting experiences.

To see a full list of what's new in 2025 Q1 (19.0.25.211), see our release notes.

Telerik Reporting is licensed per developer and has two licensing models: an annual Subscription License and a Perpetual License. The Subscription license provides access to the latest product updates, technical support, and exclusive benefits for a flat annual fee, and must be renewed to continue using the software. The Perpetual license is a one-time purchase granting access to the current released version and includes a one-year subscription for product updates and technical support. After this initial period, users can choose to renew the subscription element to continue receiving updates and support; otherwise, they may continue using the installed version available during their active subscription term but will forgo future updates and support. See our Telerik Reporting licensing page for full details.

Telerik Reporting is available to buy in the following products:
