# Property bindings properties

By defining **property bindings**, you can link specific properties of an element directly to an **external data source**. Once bound, the element's property will **automatically update** in real-time when the value in the data source changes.

For example, if you bind the **Visible** property of an element to a value in an XML file, the element will automatically show or hide as that value changes.

***

### **Property Bindings Overview**

The **Property Bindings** section lists all element properties that can be dynamically bound to a data source. To set up a binding, you must specify **at least** the following:

* **Data Provider** (the external source)
* **Column** (the specific data field)
* **Row** (the data record)

***

### **Fields and Definitions**

| **Field**         | **Description**                                                                                                          |
| ----------------- | ------------------------------------------------------------------------------------------------------------------------ |
| **Property**      | The element property to be bound (system-defined and cannot be changed).                                                 |
| **Type**          | The data type of the property to be bound (system-defined and cannot be changed).                                        |
| **Data Provider** | The data provider representing the external data source to bind (must be added beforehand).                              |
| **Column**        | The data field (column) of the data source to bind.                                                                      |
| **Row**           | The specific record (row) of the data source to bind.                                                                    |
| **Scroll**        | Enable this to apply data scrolling if desired. If switched on, **data scrolling properties** will apply to the binding. |

***

### **Important Notes and Limitations:**

* **Property binding options vary depending on the type of element.** Not all properties can be bound for every element type.
* **Limitation on playlist duration scrolling:** Property bindings **do not** detect or follow scrolling based on **local playlist duration**. This type of scrolling is element-specific and cannot synchronize with property bindings.
* **Limitation inside Table Elements:** When an element is placed inside a **Table Element**, data refreshes occur in sync with the **Table's refresh cycle**, not independently.

### **Tip:**

For more information on how to write proper binding values, refer to the **[Property Bindings Values](#)** page that details the exact formats and notation for binding values (e.g., booleans, colors, sizes).
