Accessing DataObject Attributes/Fields for Custom UI Behavior

[askforanky]

Hi team,

I would like to understand how to access attributes or fields inside a DataObject so I can implement custom UI functionality.
Specifically, I’m looking for guidance or examples on how to:

• Show or hide a field based on the value of another field
• Enable or disable fields dynamically
• Populate dropdown options when another dropdown’s value changes
• Perform any other custom logic that depends on field values within the DataObject

Are there recommended APIs, hooks, or patterns within the framework for interacting with DataObject fields at runtime? Any sample code or best practices would be very helpful.
