The keyboard navigation of the Grid is always available.
For a complete example, refer to the demo on using the keyboard navigation of the Grid.
The Grid supports its keyboard navigation functionality through the
Navigatable() method. When enabled, you can initially select a row or cell and then move within the Grid by using the
Arrow keys. The navigation occurs at a cell level regardless of what the
Selectable() mode is. To select the current row or cell, press
The following example demonstrates how to enable the key navigation in the Grid.
/* Other configuration. */
The keyboard navigation of the Grid works by listening to the
keydown events on the wrapper element of the helper. Its behavior is based on the assumption that whatever the user does is in accordance with the currently focused Grid cell and not with the focused element of the browser. If the data cells of the Grid contain hyperlinks that have to be activated through the keyboard:
- Navigate to the respective Grid cell by using the
Enterto focus the hyperlink inside the cell.
To return the focus on the table cell, press
Esc. In order for the hyperlinks to be inaccessible through tabbing, set the
tabindex="-1" attribute to the custom hyperlinks.
You can also avoid the procedure and bypass the keyboard navigation of the Grid, access the custom hyperlinks with tabbing, and activate them with
Enter. To achieve this, prevent the
keydown event bubbling of the custom hyperlinks. As a result, the
Enter key-presses will be unnoticed by the Grid.
