Description

Keyboard navigation provides all web and app users with a fast keyboard-only navigation capability and is also part of the web accessibility features–it enables users with disabilities to fully control their website or app access through the keyboard.

By default, users can only navigate to links, buttons, and form controls with a keyboard. The navigation order in which interactive items receive keyboard focus has to be logical and intuitive. Generally, keyboard navigation logic needs to follow the visual horizontal and vertical flow of the page, for example, left to right and top to bottom, header first followed by the main and then the page navigation.

The keyboard navigation of the Chart is always available as demonstrated in this demo.

The Telerik UI for ASP.NET Core Chart component is part of Telerik UI for ASP.NET Core, a professional-grade UI library with 110+ components for building modern and feature-rich applications. The UI for ASP.NET Core Chart is a server-side wrapper for the Kendo UI for jQuery Chart component and supports an HtmlHelper and a TagHelper mode.

The Chart supports the following keyboard shortcuts:

Actions Applied on the Chart Area

  • Right Arrow Moves focus to the next point in the series. If focus is on the last point of the series, moves focus to the first point of the next series.
  • Left Arrow Moves focus to the previous point in the series. If focus is on the first point of the series, moves focus to the last point of the previous series.
  • Down Arrow Moves focus to the next series.
  • Up Arrow Moves focus to the previous series.
  • Tab Moves the focus to the legend area. If the legend is not visible, or if legend position is `top` or `left`, moves focus to the next focusable element on the page.
  • Shift + Tab Moves the focus to the previous focusable element on the page. If legend position is `top` or `left`, moves focus to the legend area.

Actions Applied on the Chart Legend

  • Arrow Keys Navigate over the legend items.
  • Tab Moves the focus to the next focusable element on the page. If the legend position is `top` or `left`, moves focus to the chart area.
  • Shift + Tab Moves the focus to the chart area. If the legend position is `top` or `left`, moves focus to the previous focusable element on the page.
