By switching to the new UCI interface. We notice that several buttons have been added to the ribbon, and sub-grid. For example, the refresh button:
It’s possible to hide this button using the latest version of Ribbon Workbench. In this tutorial, I use the version 3.1.391.1 available on XrmToolBox.
I created a solution containing the Price list items entity (productpricelevel), and I open it using the Ribbon Workbench.
As you can see in the image below, a new tab has been added to this version of Ribbon Workbench.
Now, if you want to hide the refresh button from subgrid header. Go to the UNIFIED INTERFACE Tab, search the refresh button in the subgrid area. The button doesn’t have a label, you need to check the Ids. Then right-click, and click Hide.
