Keyboard Support

A critical requirement for software accessibility is keyboard support as a complete alternative to pointing devices (mouse, etc.). Keyboard support is comprised of command key, focus key, and keyboard navigation. RadListBox seamlessly switches between mouse and keyboard navigation, allowing items selection, deletion, moving and reordering.

Setting the control's KeyboardNavigationSettings, allows you to associate an activation combination (CommandKey + FocusKey), which moves focus to the RadListBox. When there are multiple RadListBox controls on a given page, each of them may have a different activation combination.

The KeyboardNavigationSettings section is available as of R2 2016 (version 2016.2.504). Older versions rely on the AccessKey DOM attribute to receive focus.

Keyboard Navigation Settings

The KeyboardNavigationSettings exposes two properties to configure the keyboard combination that sets focus to the control:

  • CommandKey: [Ctrl] , [Alt] or [Shift].

  • FocusKey: An upper-case letter or number.

Pressing CommandKey + FocusKey sets the focus on the RadListBox and enables keyboard navigation.


Certain keyboard combinations are reserved and used as shortcuts in the browsers.

<telerik:RadListBox ID="RadListBox1" runat="server" >
    <KeyboardNavigationSettings CommandKey="Alt" FocusKey="M" />
        <telerik:RadListBoxItem Text="Amsterdam" >
        <telerik:RadListBoxItem Text="Barcelona" >

Arrow Navigation / Selection

  • Down Arrow / Up Arrow keys select next/previous item.

  • Shift + Arrow Keys selects multiple items.

  • Ctrl + Space adds or removes the currently active item to or from the selection.

  • Del deletes the currently selected item (if AllowDelete is set to "true").


  • Ctrl + Right Arrow transfers the selected item/s to the destination RadListBox.

  • Ctrl + Left Arrow transfers the selected item/s to the source RadListBox when the selection is in the destination listbox.


  • Ctrl + Shift + Up Arrow reorders upwards.

  • Ctrl + Shift + Down Arrow reorders downwards.

Mark Matches


  • Start typing to highlight the matching items.

  • Esc clears the mask.

  • Backspace removes a single character.


  • Any key navigates to a matching item.

  • Subsequent press on the same key iterates over the matches.


Marking matches works only for the built-in items, because it relies on their Text and structure. This means that using the ItemTemplate will disable the Mark Matches functionality.
