Power BI External Users and Data Security

Power BI lets you share content directly with external users for B2B and B2C scenarios. When the benefits of this sharing option outweigh its limitations (read-only reports, requiring Azure AD federated access, per-user licensing, rendering the report inside Power BI), this is the easiest way to share Power BI content with an external party. However, the documentation, which is otherwise excellent, doesn't explain the steps…

Expression-based Formatting in Power BI

If you have used SSRS, you know that paginated reports are very customizable, and you can make almost any property expression-based. Power BI is yet to deliver expression-based properties to change settings based on runtime condition, such as to change the font style based on the actual value or user selection. Currently, there are two places where you can use a DAX measure for expression-based…
