# Event Basics

## Raising an Event

Providers can raise data events by creating an instance of the `wire.data.DataEvent` class, specifying the name of the event and then calling the `raise` method.

```javascript
new wire.data.DataEvent("myevent").raise();
```

## Listening for an Event

Consumers can listen for events by registering a listener as a function callback with the WireBootstrap Data Event Manager.  Use the `listen` method on `wire.data` to create a new listener.

```javascript
wire.data.listen().event("myevent").when((data) => {
   ...   
});
```

## Standard Events

Methods are available on `wire.data.DataEvent` class for creating standard data events in the system.

### DataSelect

The `dataselect`event is used primarily by WireBootstrap components to let other components know when a user selects or changes data inside the component.  

```javascript
const dataevent = new wire.data.DataEvent().dataselect();
```

### DataWrite

The `datawrite`event is used primarily by WireBootstrap components to let other components know a user has saved data to a data service.

```javascript
const dataevent = new wire.data.DataEvent().datawrite();
```
