This will result in up to 7 events. The first and last cell in the range will cause two events each. This is due to the first cell firing an event with started=true, finished=true upon mousedown with an additional event started=true, finished=false while in the range, and the last cell firing an event started=false, finished=false as soon as it is in the range and then again started=false, finished=true upon the end of cell selection.

# Cell Selection API Reference

## Configuration API

| Property | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| `suppressMultiRanges` | `boolean` |  |  |  |
| `enableHeaderHighlight` | `boolean` |  |  |  |
| `enableColumnSelection` | `boolean` |  |  |  |
| `handle` | `RangeHandleOptions \| FillHandleOptions` |  |  |  |

## Selection Events

| Property | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| `cellSelectionChanged` | `CellSelectionChangedEvent` |  |  |  |
| `fillStart` | `FillStartEvent` |  |  |  |
| `fillEnd` | `FillEndEvent` |  |  |  |

As an example to illustrate the `cellSelectionChanged` event, if selecting a range of 5 cells in a row, the user will click the first cell and drag to the last cell. This will result in up to 7 events. The first and last cell in the range will cause two events each. This is due to the first cell firing an event with `started=true, finished=true` upon mousedown with an additional event `started=true, finished=false` while in the range, and the last cell firing an event `started=false, finished=false` as soon as it is in the range and then again `started=false, finished=true` upon the end of cell selection. All the intermediary events will have one event with both `started` and `finished` as `false`. This is illustrated in the table:

| User action | `started` | `finished` |
| --- | --- | --- |
| `mousedown` in first cell | `true` | `true` |
| `mousemove` in first cell | `true` | `false` |
| `mousemove` in intermediate cells | `false` | `false` |
| `mousemove` in final cell | `false` | `false` |
| `mouseup` in final cell | `false` | `true` |

The example below also illustrates this by logging the event fields in the console:

#### cellSelectionChanged

```ts
import { Component } from "@angular/core";
import { HttpClient } from "@angular/common/http";
import { AgGridAngular } from "ag-grid-angular";
import {
  CellSelectionOptions,
  ClientSideRowModelModule,
  ColDef,
  ColGroupDef,

  enableDevValidations,
} from "ag-grid-community";
import {
  CellSelectionModule,
  ClipboardModule,
  ColumnMenuModule,
  ContextMenuModule,
} from "ag-grid-enterprise";

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

ModuleRegistry.registerModules([
  ClientSideRowModelModule,

]);
import { IOlympicData } from "./interfaces";

@Component({
  selector: "my-app",
  standalone: true,
  imports: [AgGridAngular],
  template: `<ag-grid-angular
    style="width: 100%; height: 100%;"

    (gridReady)="onGridReady($event)"
  /> `,
})
export class AppComponent {
  columnDefs: ColDef[] = [
    { field: "athlete", minWidth: 150 },

  ];
  defaultColDef: ColDef = {

    minWidth: 100,
  };
  rowData!: IOlympicData[];

  constructor(private http: HttpClient) {}

  onCellSelectionChanged(e: unknown) {
    console.log(e);
  }

  }
}
```

## Editing Events

| Property | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| `cellEditRequest` | `CellEditRequestEvent` |  |  |  |
| `cellSelectionDeleteStart` | `CellSelectionDeleteStartEvent` |  |  |  |
| `cellSelectionDeleteEnd` | `CellSelectionDeleteEndEvent` |  |  |  |

## Cell Selection API

The following methods are available on the `GridApi` for managing cell selection.

| Property | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| `getCellRanges` | `Function` |  |  |  |
| `addCellRange` | `Function` |  |  |  |
| `clearCellSelection` | `Function` |  |  |  |

Cell ranges are normally bounded by a start and end row. However it is also possible to define a range unbounded by rows (i.e. to contain all rows). When adding an unbounded range via `gridApi.addCellRange`, do not provide start or end row positions.

Row positions are defined by a row index and pinned. Row indexes are integers starting at zero. Pinned can be either `'top'` (row is in pinned top section), `'bottom'` (row is in pinned bottom section) or `null` (row is in the main body). See [Row Pinning](https://www.ag-grid.com/archive/36.2.0/angular-data-grid/row-pinning/) for information on row pinning.

Ranges are defined by a list of columns. Pass in either a) a list of columns or b) a start and end column and let the grid work out the columns in between. Passing a list of columns instead of a start and end column has the advantage that the columns do not need to be contiguous.
