Choosing font color based on background color in Power BI

In August 2018, the Power BI team has released a new feature: conditional formatting by field value. This feature works for both background colors and font colors. Because different background colors require different font colors for text to be legible,  it makes sense to use both at the same time. In this blog post, I am showing how you can dynamically choose the font color depending on the background color. Continue reading “Choosing font color based on background color in Power BI”

Changing outer background of Power BI reports

When you publish a Power BI report to web, its outer background color will be grey by default. This may be undesirable if your report does not fit the screen perfectly, which will likely happen, because not all screens are of the same size and ratio. This blog post shows how you can change the outer background color. Continue reading “Changing outer background of Power BI reports”

Switching from imported data to DirectQuery or Live Connection in Power BI

You can switch from Import to DirectQuery or Live Connection, and from DirectQuery to Live Connection

In some cases, it may be necessary to separate a Power BI report from its dataset. For example, you may want to have multiple reports based on a single dataset, or you may have upgraded to Analysis Services. Currently, Power BI Desktop does not provide a simple way of switching from imported data to Live Connection or DirectQuery, but there are some workarounds.

Configuring “all” access with dynamic row-level security

Row level security

Row-level security is an important part of many data models. In this article, I am showing a way to selectively grant “all” access with dynamic row-level security and only one role. For example, we can let a CEO see the whole data model, but a department head will be able to see their department’s data only. This article presents a more flexible approach in cases where using an organizational hierarchy and PATHCONTAINS would be inappropriate.

Extracting images and themes from Power BI Desktop files

Learn how to extract images and themes from your Power BI Desktop files (.pbix)

A colleague of mine has recently asked to provide him a background image from a Power BI Desktop file I have had shared with him previously. Because sometimes the original images are lost and only preserved in .pbix files, I figured a quick blog post about extracting the images would be useful. Custom themes too can be extracted in the same way. Continue reading “Extracting images and themes from Power BI Desktop files”
