DAX for Power BI videos | DAX for Power BI Part 8.1 - The Values, HasOneValue and SelectedValue Functions

Posted by Andrew Gould on 07 August 2022

DAX for Power BI Part 8.1 - The Values, HasOneValue and SelectedValue Functions

This video shows you how to reference the values of a column in a measure expression. You'll learn how to use the Values or Distinct functions to return a list of unique values for a column. You'll see how to use HasOneValue or HasOneFilter to check if only one unique value has been returned. You'll also learn how to use the SelectedValue function to replace a combinatiion of the If, HasOneValue and Values functions. The video also explains how to use these functions for several practical examples in Power BI, including creating dynamic visual titles with sync slicers and drill through filters, as well as how to create a basic disconnected slicer.

This video is currently only available to YouTube channel members in the appropriate tier. If you’re already a channel member, you can watch the video on YouTube; otherwise, click here to see the perks of becoming a channel member.
