FileManager

Accessibility Support

Out of the box, the Telerik and Kendo UI FileManager provides extensive accessibility support and enables users with disabilities to acquire complete control over its features.

The FileManager is compliant with the Web Content Accessibility Guidelines (WCAG) 2.2 standards and Section 508 requirements, follows the Web Accessibility Initiative - Accessible Rich Internet Applications (WAI-ARIA) best practices for implementing the keyboard navigation for its component role, provides options for managing its focus and is tested against the most popular screen readers.

WAI-ARIA

This section lists the selectors, attributes, and behavior patterns supported by the component and its composite elements, if any.

The FileManager component is a composite component that is used to represent file system-like structure. It contains:

• ToolBar - on top of the component
• Splitter - it separates the panes in the component
• TreeView - in its left pane.
• Breadcrumb - in the top of its center pane
• ListView or a Grid - in its center pane.
• k-filemanager-preview element - in its right pane

Each component implements its own dedicated ARIA spec.

The FileManager component integrates the ToolBar component and follows its WAI-ARIA spec:

The component that organizes the inner structure of the FileManager is a Splitter:

The main navigation component in the FileManager is the TreeView:

The helper navigation component in the FileManager is the Breadcrumb:

The component placed in the main pain of the FileManager can be a selectable ListView:

or it can be a Grid:

Apart from that the .k-filemanager-preview element must be focusable, so that its content would be comunicated to the users:

Managing the Focus

The FileManager component is a container that consists of the following inner components and elements:

• Toolbar (role=toolbar);
• Splitter (role=separator) (there are one or two focusable splitbar elements, depending is the preview element is activated);
• TreeView (role=tree);
• Breadcrumb (role=navigation);
• Grid (role=grid), or ListView (role=listbox)
• k-filemanager-preview element;

Each of them is part of the page tab sequence and implements its own navigation spec. The ToolBar, TreeView, ListView, Grid and the k-filemanager-preview element are single-tab-stop components. The Breadcrumb features a tab stop for each of its rendered items. The Splitter has a tab stop on each of its splitbars.

The FileManager does not implement any dedicated key shortcuts. Instead it features the shortcuts available in its inner components.
