# OnValueChangedReconnect

The **OnValueChangedReconnectInterface** component is designed to work in combination with [Runtime Persistence](/basics/runtime-ui/runtime-persistence.md). It ensures that when a connection-related property is modified, the associated interface is properly reinitialized by disconnecting and reconnecting automatically.

### **How It Works**

1. **Triggered on Value Change**
   * This script provides a **public method** that can be invoked when a **property changes** (e.g., an IP address in Runtime Persistence).
2. **Automatic Interface Reconnection**
   * After the method is called, the script **disconnects** the interface.
   * It then **waits for the specified delay** before **reconnecting** to ensure reinitialization.
3. **Ensures Proper Communication**
   * Necessary when **network properties or connection settings** change dynamically.
   * Prevents the need for a **manual restart** when modifying connection parameters.

## 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://doc.realvirtual.io/components-and-scripts/interfaces/interface-tools/onvaluechangedreconnect.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.
