One of FileMaker's most advantageous tools added in recent years is the Button Bar. It was the first way to present dynamic, calculated content directly on the screen. This removed the need for the decades-long practice of adding "yet another unstored calculation field." You can calculate something and render it right on the screen.

Then, in FileMaker 20, we got a new layout object called Layout Calculations. While these now provide the same functionality as a Button Bar, they do so without the overhead of unnecessary behind-the-scenes CSS and other extras. However, they are not fully implemented; they don't update any of their calculation references. While this will eventually be fixed, there are unique uses for Layout Calculations that allow for some really cool features—like Render Fields.

In this video, we take a look at generating temporary images for the purpose of PDF generation, which then cease to exist after the script finishes running. These Render Fields can be 100% dynamic on a record-by-record basis and can display whatever you want using an unstored field to show the result. This allows you to multi-purpose a field for multiple layouts. Let's take a look at what Render Fields can provide for your FileMaker solution.
