Inline cell editing for the React Data Grid — built-in text, number and select editors, validation, and a popup contract for rich editors like date pickers and multi-selects.
editing turns cells editable in place. Press Enter or F2
on the active cell — or double-click any cell — to start; Enter
commits, Escape cancels, Tab commits and moves to the next
editable cell. Editing builds on
keyboard navigation, so editing enables
cellNavigation automatically.

}Usage
Editing is opt-in per column — editable picks a built-in editor, a custom
editor component is itself the opt-in:
<CDataGrid
editing
columns={[
{ key: 'name', editable: true }, // text input
{ key: 'age', editable: { type: 'number', min: 0 } }, // number input
{ key: 'role', editable: { type: 'select', options: ['admin', 'user'] } },
]}
items={items}
/>The app owns the data
The grid never mutates items. A commit calls onEditCommit with
{ item, columnId, value, previousValue } — apply the change to your state and
the grid re-renders (server-side, PATCH and refetch):
<CDataGrid
editing
columns={columns}
items={items}
onEditCommit={({ item, columnId, value }) =>
setItems((current) =>
current.map((row) => (row.id === item.id ? { ...row, [columnId]: value } : row))
)
}
/>onEditStart and onEditCancel fire around it with (item, columnId).
Tracking edits
editTracking keeps the value each cell had before its first commit, keyed by
itemKey. A cell whose value in items differs from it gets
data-grid-cell-edited: a marker in its corner, and the description “Edited”
for screen readers (labels.editedCell). The grid compares with the data you
pass, so a commit you refuse or apply later, an undo, and an edit back to the
old value all show the right state. Edit a name or a role below, then save.

}Pass a ref as gridRef to reach the grid API: isDirty() says whether
anything changed, getEditedCells() returns
{ rowId, columnId, item, value, originalValue } for each edited cell, and
clearEdited() forgets the original values once you have saved.
onEditedChange receives the edited cells whenever their set changes.
Without itemKey a row’s id is its position in items, so an insert or a
removal would move a mark to another row; tracking stays off and logs an
error. editEquals(value, originalValue) on a column decides what counts as
a change, for values a new object replaces on every commit such as dates or
arrays; the default is Object.is. The same comparison runs when an editor
closes: a commit that keeps the value fires the cancel event instead of the
commit, before editValidate, and adds nothing to the undo history, with or
without tracking. To tint whole rows as well, return a class from rowClass
for the rows listed in the edited cells.
Validation
editValidate gates the commit. Return true to accept, or a message to block
it — the editor gets aria-invalid, the is-invalid class and an
aria-errormessage pointing at the message:
{ key: 'name', editable: true, editValidate: (value, item) => value !== '' || 'Name is required' }An invalid value keeps the editor open; Escape still cancels.
Validating the data
validate checks the data itself, not only the cell being edited. It receives a row
and returns messages keyed by column: a string is an error, and
{ message, level: 'warning' } is a warning. Every rendered cell with an issue is
marked, data loaded from the server included: an error gets
data-grid-cell-invalid (a solid outline), and aria-invalid when cell
navigation is on, a warning gets
data-grid-cell-warning (a dashed outline), and both carry the message as a
tooltip and as their description for screen readers. Because the function sees
the whole row, one rule can compare fields, and fixing either field clears the
mark.

}When an edit commits, the grid validates the row as it will be after the change,
after editValidate and only when the value changed, so a cell loaded with an
error can still be left with Enter. An error on the edited column blocks the
commit and shows the message in the editor, like editValidate. An error the
commit causes on another column lets it through, marks that cell and is announced
to screen readers; warnings never block.
isValid() and getInvalidCells(level?) on gridRef check every row the grid
holds, not only the rendered ones, for example to disable a save button. Read them
in an effect, as the example does: during your own render the grid has not seen
the new items yet. With dataProvider they see the rows the grid holds: the current page, or every
page loaded so far with infiniteScroll, never the rest of the server’s data.
The grid keeps no state for this: errors your server returns can live in your own
state and be read by validate. Key them to the value the server rejected
(serverErrors[item.id]?.email === item.email ? 'Email is taken' : undefined),
otherwise the old message blocks every new value the user types into that cell.
When that state changes, pass a new validate function so the grid renders again.
Custom editors
editor replaces the built-in input with your own component. It renders with
the editing context and registers the imperative bits of the contract through
handleRef:
import type { CDataGridEditorProps } from '@coreui/react-data-grid'
import { useEffect, useRef } from 'react'
const NoteEditor = ({ value, handleRef }: CDataGridEditorProps) => {
const inputRef = useRef<HTMLInputElement | null>(null)
useEffect(() => {
const input = inputRef.current
handleRef({
focus: () => input?.select(),
getValue: () => input?.value,
})
return () => handleRef(null)
}, [])
return <input className="form-control form-control-sm" defaultValue={String(value ?? '')} ref={inputRef} />
}
// columns: [{ key: 'note', editor: NoteEditor }]The component receives { item, column, value, invalid, labels, commit, cancel, handleRef };
the handle can provide getValue (feeds Enter/Tab/blur/outside commits),
focus, and contains (extends the edit scope to overlays portaled outside the
cell).
Rich editors — date pickers, autocompletes, multi-selects
Editors whose UI extends beyond the cell — a date range picker’s calendar, a
multi-select’s listbox — set editorPopup: true on the column. The grid renders
them in a .data-grid-editor-popup layer anchored to the cell (min-width = cell
width), so a tall editor never reflows the row, and the cell keeps its content
underneath.
Three rules make components like @coreui/react-pro’s
CDateRangePicker, CTimePicker, CAutocomplete and CMultiSelect work as
editors:
- Commit on outside, not on blur alone. Picking a date in a calendar blurs
the input mid-edit — so the grid commits on pointerdown outside the edit
scope (cell + popup + anything
contains()claims). Keep the component’s overlay inside the popup (itscontainerprop), or claim a portaled overlay via the handle’scontains(). - One Escape, one layer. An Escape the editor consumed (calling
preventDefault()to close its own overlay) never cancels the edit — only the next, unconsumed Escape does. - Values are not scalars.
getValue()can return anything — a range picker commits{ startDate, endDate }, a multi-select commits an array;onEditCommitpasses it through untouched.
const PeriodEditor = ({ value, handleRef }: CDataGridEditorProps) => {
const range = useRef(value as { startDate?: string; endDate?: string } | undefined)
useEffect(() => {
handleRef({ getValue: () => range.current })
return () => handleRef(null)
}, [])
return (
<CDateRangePicker
startDate={range.current?.startDate}
endDate={range.current?.endDate}
onStartDateChange={(startDate) => (range.current = { ...range.current, startDate })}
onEndDateChange={(endDate) => (range.current = { ...range.current, endDate })}
/>
)
}
// columns: [{ key: 'period', editor: PeriodEditor, editorPopup: true }]Interaction details
- Scrolling the editing row out of the virtualized window commits the draft; so do sort, filter and page transitions.
- Replacing
itemsand server-side data loads cancel an in-flight edit — the incoming data owns the cell. - Shift+Tab commits and moves to the previous editable cell.
