Angular Data Grid Keyboard Navigation

Keyboard navigation

APG grid keyboard navigation for the Angular Data Grid — role="grid", a roving-tabindex active cell and arrow-key movement across header and data cells.

On this page

cellNavigation switches the grid to the ARIA grid pattern: the table gains role="grid", exactly one cell is tabbable at a time (a roving tabindex), and the arrow keys move a visible active cell across header and data cells. Click a cell below, then navigate with the keyboard.

import { Component } from '@angular/core'
import { DataGridComponent } from '@coreui/angular-data-grid'
import type { DataGridColumn, DataGridItem } from '@coreui/angular-data-grid'

const roles = ['admin', 'editor', 'viewer']

@Component({
  selector: 'docs-data-grid-keyboard-navigation-example',
  imports: [DataGridComponent],
  template: `
    <c-data-grid
      [cellNavigation]="true"
      [columns]="columns"
      [items]="items"
      [itemKey]="itemKey"
      [rowSelection]="true"
    />
  `
})
export class DataGridKeyboardNavigationExample {
  readonly columns: DataGridColumn[] = [
    { key: 'id', label: '#', width: 90 },
    { key: 'name', label: 'Name' },
    { key: 'email', label: 'Email', style: { width: '30%' } },
    { key: 'role', label: 'Role', width: 110 }
  ]
readonly items: DataGridItem[] = Array.from({ length: 200 }, (_, i) => ({
    id: i + 1,
    name: `User ${i + 1}`,
    email: `user${i + 1}@example.com`,
    role: roles[i % roles.length]
  }))
readonly itemKey = (item: DataGridItem) => String(item.id)
}

Usage

<c-data-grid [columns]="columns" [items]="items" [cellNavigation]="true" />

cellNavigation is off by default — without it the grid keeps native table semantics and the accessible chrome it always had. Inline editing requires the active-cell model, so editing enables cellNavigation automatically.

Keys

Key	Action
Arrow keys	Move one cell; stop at the edges (no wrap). The header label row is row one — Arrow Up from the first data row reaches it.
Home / End	First / last cell in the row.
Ctrl+Home / Ctrl+End	First / last data cell of the grid.
PageUp / PageDown	Move one viewport when virtualized; move one page (and flip it) under pagination.
Tab / Shift+Tab	Leave the grid — the whole grid is a single tab stop.
Enter	Toggle sort on a sortable header cell; descend into a data cell’s interactive content (links, buttons); start editing an editable cell.
Escape	Ascend from cell content back to the cell.
Space	Toggle row selection on the active row.

Focus and virtualization

The active cell is state, not DOM: with virtualization on, navigating to an off-window row scrolls it into view first and focuses it once it renders. If the focused row is recycled out of the window while you scroll, focus parks on the viewport and the next navigation key brings the active cell back into view.

Styling

The active cell shows an inset focus ring driven by two component tokens:

c-data-grid {
  --cui-data-grid-focus-ring-width: 2px;
  --cui-data-grid-focus-ring-color: var(--cui-primary);
}
