Hi, in the ribbon we have, a certain menu can be accessed from different places (including contextual tabs). As I don't want to define the menu mulitple times (due to maintenance), I decided to add the menu as a resource. I can't just add the menu as a StaticResouce, as the element can't be rooted multiple times. So I created a style as follows:
As can be seen, the menu is always displayed in a popupbutton, so I'm setting the template for the popup here. This approach works, but leaves me with two problems:
1 - The first time the menu shows, all colors in the gallery are placed on a single line, thus creating an incredibly wide menu. The second time the menu is shown is appears ok.
2 - When all commands on the menu are disabled, the popupbutton itself is still enabled, even though the command is set to NotACommand.
How can I get rid of these problems?
