# BindingSource

The Wisej.NET `BindingSource` component simplifies data binding by providing currency management, change notification, and intermediary services between controls and data sources. Connect to data through the `DataSource` property, optionally specifying a `DataMember` for complex scenarios.

## Features

### Data Access

Access underlying data through:

* `Current`: Get or modify the current item
* `List`: Access the complete data collection

### Data Operations

Manage data with methods like:

* `RemoveCurrent`: Delete current item
* `EndEdit`: Commit changes
* `CancelEdit`: Discard changes
* `Add`/`AddNew`: Create new items

### Event Customization

Customize behavior through events:

* `CurrentItemChanged`: React to current item updates
* `DataSourceChanged`: Handle data source modifications

### Navigation Integration

Works seamlessly with the [`BindingNavigator`](/docs/controls/other-components/bindingnavigator.md) control through its `BindingNavigator.BindingSource` property for VCR-style data navigation.

### Value Refresh

The `RefreshValueOnChange` property enables automatic source property updates when data-bound values change.
