Hi,

I'm using the **Tree component in Perspective** , and I'm dynamically setting its `items` property through a script (e.g., onStartup and on a Refresh button).

In the label field of each item, I’m concatenating values like name, tag value, and unit. It works, but the values **only update when the script runs** , so it's not ideal for live updates.

Since I'm dynamically generating the whole `items` structure, I want to **bind each item's label** to a tag value + unit **through scripting** — not manually in the designer.

Is there a way to **add a binding to the `label` property of Tree items** via script, so it updates automatically when the tag changes?

Thanks in advance 🙂!

Consider leveraging property bindings directly on the items prop itself.  
Move your logic from onStartup script to items prop. Add source data using Expression / Expression Structure and use Script transform for your logic. Construct each item's label using those live values, so the Tree reflects updates in real time.

No. Run your script at a repeating pace.
