Question

You are building a PCF field component that renders a numeric slider bound to a Dataverse field. The component also exposes an input property named 'maxValue' that controls the slider's upper bound. Rebuilding the slider control is expensive, so you only want to recreate it when 'maxValue' changes, not on every framework callback. Inside the updateView method, how should you determine whether 'maxValue' changed since the last call?

Accepted Answer

Inspect the context.updatedProperties array and check whether it contains 'maxValue' before recreating the slider.

Answer

Compare context.mode.isControlDisabled to the previous frame's value stored in a class field.

Answer

Call context.parameters.maxValue.security to see if the property was refreshed by the platform.

Answer

Register an onChange handler in the manifest for 'maxValue' so updateView is skipped when other properties change.
