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 Telerik UI for ASP.NET Core ListBox is disabled by default. You can enable it through the Navigatable() option, as demonstrated in this demo.

The ListBox supports the following keyboard shortcuts:

Focus

  • Alt + W Focuses the component.

Supported Keys and User Actions

  • Up Arrow Selects the previous item.
  • Down Arrow Selects the next item.
  • Del Deletes the selected items.
  • Ctrl + Space Selects or deselects an item.
  • ShiftUp Arrow Adds the previous item to the selected items.
  • Shift + Down Arrow Adds the next item to the selected items.

 

  • Ctrl + Right Arrow Adds the selected items to the connected ListBox.
  • Ctrl + Left Arrow Adds the selected items from the connected ListBox to the current one.
  • Ctrl + Up Arrow Moves the focus to the previous item.
  • Ctrl + Down Arrow Moves the focus to the next item.
  • Ctrl + Shift + Up Arrow Shifts the selected items upwards.
  • Ctrl + Shift + Down Arrow Shifts the selected items downwards.
  • Ctrl + Shift + Left Arrow Transfers all items to the connected ListBox.
  • Ctrl + Shift + Right Arrow Transfers all items from the connected ListBox.
