在 .NET 中為圖表添加鍵盤導航

透過啟用鍵盤導航，增強 .NET 應用中的圖表協助工具性，實現更順暢的資料探索和使用者體驗改進。

Charts with keyboard navigation support are designed to improve accessibility and usability by allowing users to explore chart data using only the keyboard. This feature is especially valuable for users who rely on assistive technologies or prefer keyboard interaction over a mouse. It typically includes capabilities like navigating between data points, series, or chart elements using arrow keys, accessing tooltips or data labels, and sometimes triggering events like selection or focus changes, all through the keyboard.

Several .NET chart components support keyboard navigation, including:

  • DevExpress ASP.NET MVC Chart (part of DevExpress ASP.NET and Blazor) supports accessibility features, allowing keyboard interaction across UI components.
  • Telerik UI for ASP.NET Core Charts (part of Telerik UI for ASP.NET Core) includes support for arrow key movement between data points and ARIA integration.
  • jQWidgets Chart (part of jQWidgets) is part of a framework that emphasizes WAI-ARIA compliance and keyboard interaction across its widgets.
  • Syncfusion .NET MAUI Charts (part of Syncfusion Essential Studio Enterprise) is built on a platform supporting keyboard input, extendable to visual components in custom apps.

Telerik UI for ASP.NET Core, MVC 和 Blazor 允許使用者使用簡單的文本提示重塑、導航和匯出資料。

Telerik UI for ASP.NET Core, MVC, and Blazor are component libraries for building modern web apps with .NET. Each provides a rich set of customizable UI elements, like grids, charts, and forms, tailored to its respective framework, helping developers create responsive, interactive, and accessible user interfaces.

The latest update to the Telerik UI DataGrid introduces AI-driven controls that respond to natural-language prompts, making it easier for users to work with complex datasets. Users can now reorder, resize, and toggle column visibility just by describing what they want. Pagination, row selection, and data export to Excel, PDF, or CSV formats can also be handled through conversational input, reducing clicks and improving accessibility for both technical and non-technical users.

Telerik UI for ASP.NET Core, UI for MVC, and UI for Blazor are all licensed per developer and have two licensing models: an annual Subscription License and a Perpetual License. The Subscription License 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. See our Telerik UI for ASP.NET Core, Telerik UI for ASP.NET MVC or Telerik UI for Blazor licensing pages for full details.

Telerik UI for ASP.NET Core, Telerik UI for ASP.NET MVC and Telerik UI for Blazor are available to buy individually or as part of the following products:

重用帶有靈活子報表的報表部分

將模組化報表嵌入主版面設計以簡化複雜場景並減少資料來源間的重複邏輯。

Subreports allow independently maintained reports to be embedded within a master report, enabling a modular and flexible reporting design. Each Subreport can be created, maintained, and reused separately, while connecting to the master report through parameters that dynamically filter its data from a separate data source. This approach simplifies complex reporting scenarios, improves consistency, and reduces maintenance effort by avoiding duplicated logic. Common use cases include displaying detailed line items within summary reports, combining data from multiple databases, or reusing standardized sections such as invoices, audit details, or customer histories across multiple reports.

Several ASP.NET Core reporting controls offer support for subreports including:

  • DevExpress Reporting lets you embed reusable subreports, link multiple data sources via parameters, and manage complex report structures efficiently.
  • TX Text Control .NET Server for ASP.NET facilitates dynamic subreports for documents, enabling separate data sources and parameter-driven content reuse.
  • Telerik Reporting allows you to design modular subreports, pass contextual parameters, and combine independent data queries within reports securely.
  • FastReport .NET WEB lets you integrate flexible subreports, filter datasets through parameters, and reuse report components across web applications easily.
