# 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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.wisej.com/docs/controls/other-components/bindingsource.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
