Data Grid - Editing
The data grid has built-in edit capabilities that you can customize to your needs.
Cell editing
Cell editing allows editing the value of one cell at a time.
Set the editable
property in the GridColDef
object to true
to allow editing cells of this column.
<DataGrid columns={[{ field: 'name', editable: true }]} />
Start editing
If a cell is editable and has focus, any of the following interactions will start the edit mode:
- A Enter keydown
- A Backspace or Delete keydown. It will also delete the value and stops the edit mode instantly.
- A keydown of any printable key, for instance
a
,E
,0
, or$
- A double click on the cell
- A call to
apiRef.current.setCellMode(id, field, 'edit')
./** * Set the cellMode of a cell. * @param GridRowId * @param string * @param 'edit' | 'view' */ setCellMode: (id: GridRowId, field: string, mode: GridCellMode) => void;
Stop editing
If a cell is in edit mode and has focus, any of the following interactions will stop the edit mode:
- A Escape keydown. It will also roll back changes done in the value of the cell.
- A Tab keydown. It will also save and goes to the next cell on the same row.
- A Enter keydown. It will also save and goes to the next cell on the same column.
- A mousedown outside the cell
- A call to
apiRef.current.setCellMode(id, field, 'view')
.
Control cell editability
In addition to the editable
flag on columns, control which cell is editable using the isCellEditable
prop.
In this demo, only the rows with an even Age
value are editable.
The editable cells have a green background for better visibility.
<DataGrid
className={classes.root}
rows={rows}
columns={columns}
isCellEditable={(params) => params.row.age % 2 === 0}
/>
Controlled editing
The editRowsModel
prop lets you control the editing state.
You can handle the onEditRowsModelChange
callback to control the GridEditRowsModel
state.
Column with valueGetter
You can control the committed value when the edit move stops with the onCellEditCommit
prop.
This is especially interesting when using the valueGetter
on the column definition.
<DataGrid
rows={rows}
columns={columns}
onCellEditCommit={handleCellEditCommit}
/>
Client-side validation
To validate the value in the cells, use onEditRowsModelChange
to set the error
attribute of the respective field when the value is invalid.
If this attribute is true, the value will never be commited.
This prop is invoked when a change is triggered by the edit cell component.
Alternatively, you can use the GridEditRowsModel
state mentioned in the Controlled editing section.
<DataGrid
className={classes.root}
rows={rows}
columns={columns}
editRowsModel={editRowsModel}
onEditRowsModelChange={handleEditRowsModelChange}
/>
Server-side validation
Server-side validation works like client-side validation.
- Use
onEditCellPropsChange
to set theerror
attribute to true of the respective field which will be validated. - Validate the value in the server.
- Once the server responds, set the
error
attribute to false if it is valid. This allows to commit it.
Note: To prevent the default client-side behavior, set event.defaultMuiPrevented
to true
.
This demo shows how you can validate a username asynchronously and prevent the user from committing the value while validating.
It's using DataGridPro
but the same approach can be used with DataGrid
.
Custom edit component
To customize the edit component of a column, use the renderEditCell
attribute available in the GridColDef
.
The demo lets you edit the ratings by double-clicking the cell.
Edit using external button
You can override the default start editing triggers using the event.defaultMuiPrevented
on the synthetic React events.
Events
The editing feature leverages the event capability of the grid and the apiRef. The following events can be imported and used to customize the edition:
cellEditStart
: emitted when the cell turns to edit mode.cellEditStop
: emitted when the cell turns back to view mode.cellEditCommit
: emitted when the new value is commited.editCellPropsChange
: emitted when the props passed to the edit cell component are changed.
Catching events can be used to add a callback after an event while ignoring its triggers.
The demo shows how to catch the start & end edit events to log which cell is editing in an info message:
<div style={{ height: 180, width: '100%' }}>
<DataGridPro rows={rows} columns={columns} apiRef={apiRef} />
</div>
{message && (
<Alert severity="info" style={{ marginTop: 8 }}>
{message}
</Alert>
)}
Row editing
Row editing allows to edit all the cells of a row at once.
It is based on the cell editing, thus most of the features are also supported.
To enable it, change the edit mode to "row"
using the editMode
prop, then set to true
the editable
property in the GridColDef
object of those columns that should be editable.
<DataGrid editMode="row" columns={[{ field: 'name', editable: true }]} />
Start editing
If a cell is editable and has focus, any of the following interactions will start the edit mode of the corresponding row:
- A Enter keydown
- A double click on the cell
- A call to
apiRef.current.setRowMode(id, 'edit')
./** * Sets the mode of a row. * @param {GridRowId} id The id of the row. * @param {GridRowMode} mode Can be: `"edit"`, `"view"`. */ setRowMode: (id: GridRowId, mode: GridRowMode) => void;
Stop editing
If a row is in edit mode and one of its cells is focused, any of the following interactions will stop the edit mode:
- A Escape keydown. It will also roll back changes done in the row.
- A Enter keydown. It will also save and goes to the cell at the next row at the same column.
- A mouse click outside the row
- A call to
apiRef.current.setRowMode(id, 'view')
.
Controlled editing
The editRowsModel
prop lets you control the editing state.
You can handle the onEditRowsModelChange
callback to control the GridEditRowsModel
state.
Conditional validation
Having all cells of a row in edit mode allows validating a field based on the value of another one.
To accomplish that, set the onEditRowsModelChange
prop and return a new model with the error
attribute of the invalid field set to true
.
Use the other fields available in the model to check if the validation should run or not.
Once at the least one field has the error
attribute equals to true no new value will be commited.
Note: For server-side validation, the same approach from the cell editing can be used.
The following demo only requires a value for the "Paid at" column if the "Is paid?" column was checked.
Control with external buttons
You can disable the default behavior of the grid and control the row edit using external buttons.
Here is shown how a full-featured CRUD can be created.
<DataGridPro
rows={rows}
columns={columns}
apiRef={apiRef}
editMode="row"
onRowEditStart={handleRowEditStart}
onRowEditStop={handleRowEditStop}
components={{
Toolbar: EditToolbar,
}}
componentsProps={{
toolbar: { apiRef },
}}
/>
Events
The following events can be imported and used to customize the row edition:
rowEditStart
: emitted when the row turns to edit mode.rowEditStop
: emitted when the row turns back to view mode.rowEditCommit
: emitted when the new row values are commited.editCellPropsChange
: emitted when the props passed to an edit cell component are changed.
