Data Grid Undo & Redo

Undo & redo

Undo and redo inline-edit commits in the CoreUI Data Grid — toolbar buttons and Ctrl+Z / Ctrl+Shift+Z / Ctrl+Y, with the app staying the single source of truth.

history keeps an undo/redo stack of inline editing commits. Undo with the toolbar button or Ctrl+Z (⌘Z on macOS), redo with Ctrl+Shift+Z or Ctrl+Y. Edit a few cells below, then undo your way back.

html
<div id="dataGridHistory"></div>
js
const roles = ['admin', 'editor', 'viewer']

let items = Array.from({ length: 200 }, (_, i) => ({
  id: i + 1,
  name: `User ${i + 1}`,
  age: 20 + (i % 40),
  role: roles[i % roles.length]
}))

const element = document.getElementById('dataGridHistory')

const grid = new coreui.DataGrid(element, {
  columns: [
    { key: 'id', label: '#', width: 90 },
    { key: 'name', label: 'Name', editable: true },
    {
      key: 'age', label: 'Age', width: 110, editable: { type: 'number', min: 0, max: 120 }
    },
    {
      key: 'role', label: 'Role', width: 130, editable: { type: 'select', options: roles }
    }
  ],
  items,
  itemKey: item => String(item.id),
  editing: true,
  history: true,
  toolbar: { history: true }
})

// The grid never mutates items - undo/redo re-emit editCommit with the
// values swapped, so this one handler covers edits AND their reversal.
element.addEventListener('editCommit.coreui.data-grid', event => {
  items = items.map(row => (row === event.item ? { ...row, [event.columnId]: event.value } : row))
  grid.setItems(items)
})

Usage

new coreui.DataGrid(element, {
  columns,
  items,
  editing: true,
  history: true,                  // track edit commits
  toolbar: { history: true },     // undo/redo buttons
})

The buttons stay disabled while their stack is empty; each undo/redo announces through the ARIA live region (undoneAnnouncement/redoneAnnouncement labels). grid.undo() / grid.redo() are also callable directly.

How undo works — the app stays in charge

The grid never mutates items. An undo re-emits editCommit with value and previousValue swapped (redo re-emits the original), so the same handler that applied the edit reverts it — no second code path:

element.addEventListener('editCommit.coreui.data-grid', (event) => {
  items = items.map((row) => (row === event.item ? { ...row, [event.columnId]: event.value } : row))
  grid.setItems(items)
})

History entries reference rows by id, so they survive the immutable updates this pattern produces. If a row disappears from the data entirely, its entries are dropped. New commits clear the redo stack; the stack holds the last 100 edits. Following MUI and AG Grid, undo/redo covers data edits — view changes (sorting, filters, column layout) are not tracked; persist those with stateKey instead.
