# Cell Editing

## Enable Editing

To enable Cell Editing for a Column use the `editable` property on the Column Definition.

| Property | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| `editable` | `boolean \| EditableCallback` |  |  |  |

```js
const gridOptions = {
    columnDefs: [
        {
            field: 'athlete',
            // enables editing
            editable: true
        }
    ],

    // other grid options ...
}
```

By default, the grid uses [Cell Data Types](https://www.ag-grid.com/archive/36.2.0/javascript-data-grid/cell-data-types/) to provide different editors based on the type of each column. For example, string columns will use a text input, number columns will use a numeric input.

The example below shows editing enabled on all columns by setting `editable=true` on the `defaultColDef`.

#### Simple Cell Editing

```ts
import {
  ClientSideRowModelApiModule,
  ClientSideRowModelModule,
  GridApi,
  GridOptions,
  ModuleRegistry,
  NumberEditorModule,
  TextEditorModule,
  createGrid,
  enableDevValidations,
} from "ag-grid-community";
import { IOlympicData } from "./interfaces";

if (process.env.NODE_ENV !== "production") {
  // Enable extended validations only for development
  enableDevValidations();
}

ModuleRegistry.registerModules([
  NumberEditorModule,
  TextEditorModule,
  ClientSideRowModelApiModule,
  ClientSideRowModelModule,
]);

let gridApi: GridApi<IOlympicData>;

const gridOptions: GridOptions<IOlympicData> = {
  columnDefs: [
    { field: "athlete" },
    { field: "age" },
    { field: "country" },
    { field: "year" },
    { field: "total" },
  ],
  defaultColDef: {
    editable: true,
  },
};

const gridDiv = document.querySelector<HTMLElement>("#myGrid")!;
gridApi = createGrid(gridDiv, gridOptions);

fetch("https://www.ag-grid.com/example-assets/olympic-winners.json")
  .then((response) => response.json())
  .then((data: IOlympicData[]) => gridApi!.setGridOption("rowData", data));
```

## Conditional Editing

To dynamically determine which cells are editable, a callback function can be supplied to the `editable` property on the Column Definition:

```js
const gridOptions = {
    columnDefs: [
        {
            field: 'athlete',
            // conditionally enables editing for data for 2012
            editable: (params) => params.data.year == 2012
        }
    ],

    // other grid options ...
}
```

In the snippet above, **Athlete** cells will be editable on rows where the **Year** is `2012`.

This is demonstrated in the following example, note that:

- An `editable` callback is added to the **Athlete** and **Age** columns to control which cells are editable based on the selected **Year**.
- A custom `editableColumn` [Column Type](https://www.ag-grid.com/archive/36.2.0/javascript-data-grid/column-definitions/#default-column-definitions) is used to avoid duplication of the callback for **Athlete** and **Age**.
- Buttons are provided to change the **Year** used by the `editable` callback function to control which cells are editable.
- A blue [Cell Style](https://www.ag-grid.com/archive/36.2.0/javascript-data-grid/cell-styles/) has been added to highlight editable cells using the same logic as the `editable` callback.

#### Conditional Cell Editing

```ts
import {
  CellClassParams,
  CellStyleModule,
  ClientSideRowModelApiModule,
  ClientSideRowModelModule,
  EditableCallbackParams,
  GridApi,
  GridOptions,
  ModuleRegistry,
  NumberEditorModule,
  RowApiModule,
  TextEditorModule,
  createGrid,
  enableDevValidations,
} from "ag-grid-community";
import { IOlympicData } from "./interfaces";

if (process.env.NODE_ENV !== "production") {
  // Enable extended validations only for development
  enableDevValidations();
}

ModuleRegistry.registerModules([
  RowApiModule,
  NumberEditorModule,
  TextEditorModule,
  CellStyleModule,
  ClientSideRowModelApiModule,
  ClientSideRowModelModule,
]);

let editableYear = 2012;

function isCellEditable(params: EditableCallbackParams | CellClassParams) {
  return params.data.year === editableYear;
}

let gridApi: GridApi<IOlympicData>;

const gridOptions: GridOptions<IOlympicData> = {
  columnDefs: [
    { field: "athlete", type: "editableColumn" },
    { field: "age", type: "editableColumn" },
    { field: "year" },
    { field: "country" },
    { field: "sport" },
    { field: "total" },
  ],
  columnTypes: {
    editableColumn: {
      editable: (params: EditableCallbackParams<IOlympicData>) => {
        return isCellEditable(params);
      },
      cellStyle: (params: CellClassParams<IOlympicData>) => {
        if (isCellEditable(params)) {
          return { backgroundColor: "#2244cc44" };
        }
      },
    },
  },
};

function setEditableYear(year: number) {
  editableYear = year;
  // Redraw to re-apply the new cell style
  gridApi!.redrawRows();
}

const gridDiv = document.querySelector<HTMLElement>("#myGrid")!;
gridApi = createGrid(gridDiv, gridOptions);

fetch("https://www.ag-grid.com/example-assets/olympic-winners.json")
  .then((response) => response.json())
  .then((data: IOlympicData[]) => gridApi!.setGridOption("rowData", data));

if (typeof window !== "undefined") {
  // Attach external event handlers to window so they can be called from index.html
  (<any>window).setEditableYear = setEditableYear;
}
```

## Editing Events

Cell editing results in the following events.

| Property | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| `cellValueChanged` | `CellValueChangedEvent` |  |  |  |
| `cellEditRequest` | `CellEditRequestEvent` |  |  |  |
| `rowValueChanged` | `RowValueChangedEvent` |  |  |  |
| `cellEditingStarted` | `CellEditingStartedEvent` |  |  |  |
| `cellEditingStopped` | `CellEditingStoppedEvent` |  |  |  |
| `rowEditingStarted` | `RowEditingStartedEvent` |  |  |  |
| `rowEditingStopped` | `RowEditingStoppedEvent` |  |  |  |

## Row Grouping and Cell Editing
