# Property bindings

Property bindings allow you to **dynamically link page properties** to external data sources. When the data source updates, the corresponding page property will automatically update during playback.

For example, if you **bind the Background Color** of a page to an XML file, **the background color will automatically change** when the value in the XML file changes.

***

## **Property Bindings Overview**

This section contains a **list of page properties** that can be bound to an external data source.\
To create a binding, you must define at least:

* **Data Provider**
* **Column (Field)**
* **Row (Record)**

***

### **Property**

* The **specific page property** to be bound (e.g., **Background Color**, **Visible**, etc.).
* **System-defined** — cannot be changed.

### **Type**

* The **data type** of the property (e.g., **Color**, **Boolean**, **Integer**).
* **System-defined** — cannot be changed.

### **Data Provider**

* Choose the **data provider** that supplies the data (e.g., XML, Excel, SQL, JSON).
* If no data providers are available, **create one first** in the data provider setup.

### **Column**

* Select the **data field** (column) within the data provider that contains the value for the property.

### **Row**

* Select the **record (row)** within the data provider that holds the desired value.

### **Scroll**

* **Enable this option** if data scrolling should be applied.
* When enabled, **Data Scrolling Properties** will dictate how the data is scrolled through during playback.

## **Example Use Case: Dynamic Page Visibility**

* Bind the **Visible** property of a page to a **cell in an Excel file**.
* If the Excel value is "1", the page will be shown.
* If the Excel value is "0", the page will be hidden.
* This allows **dynamic control** over which pages are shown, simply by editing the Excel file — useful for schedule-based content.

***

> **Tip**:\
> Property bindings are powerful for **real-time adaptive content**. For example:

* Change background color based on real-time sensor data.
* Show or hide pages based on external scheduling files.
* Adjust transition effects dynamically.
