# Fill Handle

When working with cell selection, a Fill Handle allows you to run operations on cells as you adjust the size of the range.

## Enabling the Fill Handle

To enable the Fill Handle, set `cellSelection.handle` to `{ mode: 'fill' }` in the `gridOptions` as shown below:

```ts
<ag-grid-angular
    [cellSelection]="cellSelection"
    /* other grid options ... */ />

this.cellSelection = {
    handle: {
        mode: 'fill',
    }
};
```

The example below demonstrates the [default behaviour](#default-fill-handle) with the minimal configuration above:

#### Fill Handle

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

  enableDevValidations,
} from "ag-grid-community";
import { CellSelectionModule } from "ag-grid-enterprise";
if (process.env.NODE_ENV !== "production") {
  enableDevValidations();
}

ModuleRegistry.registerModules([
  NumberEditorModule,
  TextEditorModule,
  ClientSideRowModelModule,
  CellSelectionModule,
]);
import { IOlympicData } from "./interfaces";

@Component({

})
export class AppComponent {

  ];
  defaultColDef: ColDef = {

    minWidth: 100,
    editable: true,
    cellDataType: false,
  };
  cellSelection: boolean | CellSelectionOptions = {
    handle: { mode: "fill" },
  };
  rowData!: IOlympicData[];

  constructor(private http: HttpClient) {}

  onGridReady(params: GridReadyEvent<IOlympicData>) {
    this.http
      .get<
        IOlympicData[]
      >("https://www.ag-grid.com/example-assets/small-olympic-winners.json")
      .subscribe((data) => (this.rowData = data));
  }
}
```

## Default Fill Handle

The default Fill Handle behaviour will be as close as possible to other spreadsheet applications. Note the following:

### Single Cell

- When a single cell is selected and the range is increased, the value of that cell will be copied to the cells added to the range.
- When a single cell containing a **number** value is selected and the range is increased while pressing the `⌥ Alt` key, that value will be incremented (or decremented if dragging to the left or up) by the value of one until all new cells have been filled.

### Multi Cell

- When a range of numbers is selected and that range is extended, the Grid will detect the linear progression of the selected items and fill the extra cells with calculated values.
- When a range of strings or a mix of strings and numbers are selected and that range is extended, the range items will be copied in order until all new cells have been properly filled.
- When a range of numbers is selected and the range is increased while pressing the `⌥ Alt` key, the behaviour will be the same as when a range of strings or mixed values is selected.

### Range Reduction

- When reducing the size of the range, cells that are no longer part of the range will be cleared (set to `null`). If your column uses a `valueParser`, it will receive an empty string (`''`) as the new value.

      .subscribe((data) => (this.rowData = data));
  }
}
```

[Live example: Fill Handle](https://www.ag-grid.com/examples/cell-selection-fill-handle/fill-handle/angular)

### Preventing Range Reduction

Reducing a range selection with the Fill Handle will clear cell contents by default, as can be observed in the [cell reduction](#range-reduction) example above.

If this behaviour for decreasing selection needs to be prevented, the flag `cellSelection.handle.suppressClearOnFillReduction` should be set to `true`.

## Fill Handle Axis

By default, the Fill Handle can be dragged horizontally or vertically. If you wish to restrict the permitted direction of dragging to either horizontal or vertical, set `cellSelection.handle.direction` to either `x` for horizontal or `y` for vertical.

```ts
<ag-grid-angular
    [cellSelection]="cellSelection"
    /* other grid options ... */ />

this.cellSelection = {
    handle: {
        mode: 'fill',
        direction: 'x', // Fill Handle can only be dragged horizontally
    }
};
```

[Live example: Fill Handle - Direction](https://www.ag-grid.com/examples/cell-selection-fill-handle/fill-handle-direction/angular)

## Double-Click Fill

When the fill handle direction is `'y'` or `'xy'`, double-clicking on the fill handle will perform a fill operation on all cells below the selected cells. Similarly, when the fill handle direction is `'x'`, double-clicking on the fill handle will perform a fill operation on all cells to the right of the selected cells.

This is enabled by default when the fill handle is enabled and does not require separate configuration.

## Fill Handle Events

When using the fill handle the grid will fire the `fillStart` event before it starts filling cells and the `fillEnd` event when all cells have been filled. See the Custom User Function example below for an example of using these events.

| Property | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| `fillStart` | `FillStartEvent` |  |  | Fill operation has started. |
| `fillEnd` | `FillEndEvent` |  |  | Fill operation has ended. |

## Custom User Function

Often there is a need to use a custom method to fill values instead of simply copying values or increasing number values using linear progression. In these scenarios, the `cellSelection.handle.setFillValue` callback should be used.

```ts
<ag-grid-angular
    [columnDefs]="columnDefs"
    [cellSelection]="cellSelection"
    /* other grid options ... */ />

this.columnDefs = [
    { field: 'country' },
    { field: 'year' },
    { field: 'sport' },
    { field: 'total' }
];
this.cellSelection = {
    handle: {
        mode: 'fill',
        setFillValue: (params) => 'Custom Fill Value',
    }
};
```

### FillOperationParams

Properties available on the `FillOperationParams&lt;TData = any, TContext = any&gt;` interface.

| Property | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| `event` | [`MouseEvent`](https://developer.mozilla.org/en-US/docs/Web/API/MouseEvent) |  |  | The mouse event for the fill operation. |
| `values` | `any[]` |  |  | The values that have been processed by the fill operation. |
| `rowNode` | [`IRowNode`](https://www.ag-grid.com/angular-data-grid/row-object/) |  |  | The RowNode of the current cell being changed. |
| `column` | [`Column`](https://www.ag-grid.com/angular-data-grid/column-object/) |  |  | The Column of the current cell being changed. |
| `initialValues` | `any[]` |  |  | The values that were present before processing started. |
| `initialNonAggregatedValues` | `any[]` |  |  | The values that were present before processing, without the aggregation function. |
| `initialFormattedValues` | `any[]` |  |  | The values that were present before processing, after being formatted by their value formatter |
| `currentIndex` | `number` |  |  | The index of the current processed value. |
| `currentCellValue` | `any` |  |  | The value of the cell being currently processed by the Fill Operation. |
| `direction` | `'up' \| 'down' \| 'left' \| 'right'` |  |  | The direction of the Fill Operation. |
| `api` | [`GridApi`](https://www.ag-grid.com/angular-data-grid/grid-api/) |  |  | The grid api. |
| `context` | [`TContext`](https://www.ag-grid.com/angular-data-grid/typescript-generics/#context-tcontext) |  |  | Application context as set on `gridOptions.context`. |

> **Note**
>
> If a `setFillValue` callback is provided, the fill handle will always run it. If the current values are not relevant to the `setFillValue` function that was provided, `false` should be returned to allow the grid to process the values as it normally would.

The example below will use the custom `setFillValue` for the **Day of the week** column, but it will use the default operation for any other column.

### Skipping Columns in the Fill Operation

The example below will use the custom `setFillValue` to prevent values in the **Country** column from being altered by the Fill Handle.

> **Note**
>
> When the `setFillValue` function returns `params.currentCellValue` that value is not added to the `params.values` list. This allows users to skip any cells in the Fill Handle operation.

> **Warning**

> Non editable cells will **not** be changed by the Fill Handle, so there is no need to add custom logic to skip columns that aren't editable.

## Read Only Edit

When the grid is in [Read Only Edit](https://www.ag-grid.com/angular-data-grid/value-setters/#read-only-edit) mode the Fill Handle will not update the data inside the grid. Instead the grid fires `cellEditRequest` events allowing the application to process the update request.

| `cellEditRequest` | `CellEditRequestEvent` |  |  | Value has changed after editing. Only fires when `readOnlyEdit=true`. |

The example below will show how to update cell value combining the Fill Handle with `readOnlyEdit=true`.

## Suppressing the Fill Handle

The Fill Handle can be disabled on a per column basis by setting the column definition property `suppressFillHandle` to `true`.

In the example below, please note that the Fill Handle is disabled in the **Country** and **Date** columns.

## API Reference

Here you can find a full list of configuration options available when the handle options are in `'fill'` mode.

| Property | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| `mode` | `'fill'` |  |  | 'fill' |
| `suppressClearOnFillReduction` | `boolean` |  | `false` | Set this to `true` to prevent cell values from being cleared when the Range Selection is reduced by the Fill Handle. |
| `direction` | `'x' \| 'y' \| 'xy'` |  | `'xy'` | Set to `'x'` to force the fill handle direction to horizontal, or set to `'y'` to force the fill handle direction to vertical. |
| `setFillValue` | `Function` |  |  | Callback to fill values instead of simply copying values or increasing number values using linear progression. |
