JavaScript/jQuery TileView - Keyboard Support
An end user can use the following keys to interact with the UI component.
| Key | Action |
|---|---|
| Shift + Mouse Wheel | Scrolls the content left/right if the direction property is "horizontal". |
| ←→↑↓ | Moves focus to the neighboring tile. |
| Home | Moves focus to the very first tile. |
| End | Moves focus to the very last tile. |
| Enter or Space | Selects the focused tile. |
You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.
jQuery
JavaScript
function registerKeyHandlers () {
const tileView = $("#tileViewContainer").dxTileView("instance");
tileView.registerKeyHandler("backspace", function(e) {
// The argument "e" contains information on the event
});
tileView.registerKeyHandler("space", function(e) {
// ...
});
