Compare to Data Binding & Expressions

Data binding, expressions, and overridable properties are used to display data during PDF/image generation.

The following are the differences:

• Data binding is useful for displaying list data or array data. It is used in the section component to bind list/array data.
• Expressions are used in properties that support expressions (usually labeled as "Support Expression"). You can use expressions to format and display data.
• Overridable properties(Property binding) allow you to change the properties of an element, such as color, font, or text. Please refer to "Overridable Properties" for a detailed explanation. They are typically used in image templates to modify the text, color, and font size of an element.

In short, use data binding and expressions to bind list/array data to section components, and use overridable properties to modify the styles of a UI element.
