Code integrity of custom visual

[DevForDay]

Is it possible to create a hash of the custom visual when we "drag" custom visual to the report?

We are trying to check if the hash code on the custom visual is the same as the code we created.

Short answer:

No, Power BI does NOT natively create or expose a "hash" of a custom visual when you drag it into a report.
There's no automatic "hash check" available inside Power BI Desktop or Service at visual-load time.

Longer explanation:

When you import or drag a custom visual (.pbiviz file) into Power BI:

• It is just loaded into memory as a visualization extension.

• Power BI does not generate a hash or verify checksum at runtime.

• Code security depends mainly on:

  • Whether it’s certified (Microsoft Certified visuals go through security validation).

  • If you manually verify the .pbiviz file before using it.

👉 Dragging a custom visual into the report doesn't trigger any background integrity or hash checking.
