# RowChangeAlertDefinition

Canonical page: https://www.adaptabletools.com/docs/reference/rowchangealertdefinition

Alert that fires when a row is added to or removed from the grid.

Set `Type` to `'RowChange'` and `RowChangeTrigger` to `'Added'` or `'Removed'`. `Scope` is `{ All: true }`. `Rule` is an optional per-row boolean expression (`[make] = 'Toyota'`); when it is omitted every matching row event fires.

```ts title="TypeScript"
export interface RowChangeAlertDefinition extends AlertDefinitionBase 
```
