# ColumnResizeResetDetail

> _Since v2.6.0_

Column resize-reset event detail.

Fired when a user-resized column is restored to its original configured width
(e.g., via the column header context menu "Reset width" action). The `width`
field reflects the column's `__originalWidth` and may be `undefined` if the
column was originally auto-sized.

#### Example

```typescript
grid.on('column-resize-reset', ({ field, width }) => {
  if (width === undefined) {
    console.log(`Column ${field} restored to auto-size`);
  } else {
    console.log(`Column ${field} restored to ${width}px`);
  }
});
```

## Properties

| Property | Type | Description |
| -------- | ---- | ----------- |
| `field` | <code>string</code> | Reset column field key. |
| `width` | <code>number &#124; undefined</code> | Original configured width in pixels, or `undefined` if auto-sized. |
