帶有 Kagi 圖表的 JavaScript 圖表控制項可以消除噪音、突出顯示突破並揭示市場動態中的供需趨勢。

Kagi charts are a technical analysis tool that display price movement through vertical lines, ignoring time to focus on significant price changes. Thick lines indicate rising demand when prices break above previous highs, while thin lines signal increased supply when prices fall below previous lows. This clear visual format helps traders filter out noise, identify trends, and spot key breakouts or reversals. Ideal for analyzing market sentiment, Kagi charts are used across stocks, forex, and commodities to support confident, data-driven trading decisions.

Several JavaScript chart components provide Kagi charts, including:

  • Wijmo FlexChart (part of Wijmo by MESCIUS) allows you to interpret price dynamics using Kagi charts, filtering noise to reveal clearer trading signals and sentiment.
  • FusionCharts Suite XT enables Kagi chart rendering to highlight price breakouts and reversals, enhancing clarity in trend-based market visualizations.
  • LightningChart JS Trader lets you visualize supply and demand shifts with Kagi charts for high-performance, real-time financial data analysis.

在篩選檢視中保留樹上下文

SmartClient 14.1 透過保持父節點可見來改進 JavaScript 應用程式中的大型資料集篩選，而不會影響伺服器邏輯或性能。

SmartClient is a powerful JavaScript component suite compatible with React, Vue, Angular, and more, designed for building large-scale, high-performance web apps. It offers advanced UI components, dynamic data handling, customizable grids, and responsive design. Ideal for enterprise use cases like financial analytics and real-time reporting, SmartClient supports seamless backend integration and delivers optimized performance and scalability.

SmartClient has enhanced hierarchical data handling with the included KeepParentsOnFilter setting, ensuring that parent nodes remain visible in filtered views, even when data is loaded dynamically. It loads "skeleton branches" via a complex client-driven algorithm, automatically managed by SmartClient, to maintain high performance without preloading the entire tree, meaning it doesn't require server-side programming. This is particularly useful in large datasets with load-on-demand trees, as it allows users to maintain full visibility into the structure of filtered results without losing context. By preserving the hierarchical path to matching records, this feature improves usability and clarity in tree-based components, especially in applications where understanding the parent-child relationship is critical.

SmartClient is licensed per developer and is available as both perpetual and subscription licenses. Product updates and technical support is also available. See our SmartClient licensing page for full details.

利用選中的組合框下拉控制項來提供節省空間的直觀多選，而不會使介面混亂。

A checked combobox is a data editor component used in user interfaces that consists of a text box with a drop-down panel. This panel displays a predefined list of items, in a clean and organized layout, from which users can input data by making a singular or multiple selections using the adjacent checkboxes. The values are then typically displayed as a comma-separated summary in the collapsed field. This type of control provides developers with a convenient way to implement multi-select functionality within their applications, and is especially effective in scenarios such as filtering datasets or configuring settings, without consuming additional space on the interface.

Several jQuery data editor collections include checked comboboxes, including:

  • DevExtreme Complete Data Editors (part of DevExtreme Complete by DevExpress) enables developers to easily integrate checked comboboxes into their jQuery applications.
  • Kendo UI for jQuery Data Editors (part of Kendo UI by Telerik) allows the integration of multi-item selection within a drop-down using checkboxes for intuitive data input.
  • jQWidgets Data Editors (part of jQWidgets) provides jQuery components that can be used to deliver multi-selection via a combobox input field with adjoining checkboxes.
  • Infragistics Ignite UI for jQuery Data Editors (part of Infragistics Professional) facilitates straight-forward data entry using a multi-select combobox with checkbox support.

使用強大的加密保護 PDF 檔，然後輕鬆將其解密，以便在需要時恢復授權使用者的存取權限。

Encrypting and decrypting PDF files is a key feature in many modern PDF components, allowing developers to protect sensitive information and control access to documents. Encryption applies a security layer to the PDF, typically requiring a password to open or modify the file, while decryption reverses the process for authorized users. These capabilities are essential for applications that handle confidential business data, legal documents, or personal records, ensuring compliance with security policies and data protection regulations.

Several JavaScript PDF controls offer the ability to encrypt or decrypt PDF files including:

  • Wijmo PDF (part of Wijmo by MESCIUS) enables developers to apply password-based encryption when generating PDFs, ensuring that only authorized users can view or alter the document.
  • Aspose.PDF for JavaScript via C++ provides robust encryption options, including support for various encryption algorithms and permission settings to restrict printing, copying, and editing, along with decryption capabilities for authorized access.
  • IronPDF for Node.js by Iron Software offers high-level methods to encrypt and decrypt PDFs, supporting both user and owner passwords, making it straightforward to secure documents before distribution and to unlock them when required.

TreeLists in UI suites are specialized components designed to display hierarchical, self-referencing data in a tabular format with expandable and collapsible rows. They combine the structure of a tree view with the functionality of a data grid, offering built-in features such as sorting, filtering, editing, and paging. This makes them ideal for scenarios where complex relationships must be presented clearly, such as organization charts, project task structures, file directories, or product categories. Their intuitive layout and powerful data management capabilities help streamline workflows and enhance the user experience in enterprise and business applications.

Several jQuery UI suites feature a treelist control including:

  • jQWidgets lets you organize hierarchical data in a grid with built-in sorting, filtering, and editing for seamless interaction and control.
  • Infragistics Professional enables you to display structured, self-referencing data in expandable rows with full support for editing, paging, and responsive layouts.
  • Kendo UI by Telerik allows you to present hierarchical tabular data with intuitive expand/collapse features, rich interactivity, and flexible data management tools.
