Hi I'm creating an excel addin that include a new ribbon tab, and I set the corresponding icon for each buton. But, anytime the excel window is resized and the button group shows an empty ball icon. How can I set an icon for the whole group to be displayed when resized?
In this image - Grouped & Ungrouped example you can see one group ("Simulation") that is not grouped, and the other groups "Add New Products" & "Scenarios" that are grouped.
