We have a UltraToolbarManager ribbon with a PopupMenuTool on it.
This PopupMenuTool has several ButtonTools on it.
The ribbon and the PopupMenuTool and the ButtonTools all have thier [toolbase].InstanceProps.KeyTip properties set to unique letters.
However, the first time the ALT+KeyTip stroke sequence is used, the keytip letter bubbles for each button in the group of buttontools do not show. Then, if you release the ALT key, then do the ALT+KeyTip stroke sequence again, the keytip letter bubbles appear.
This also happens for PopupMenuTools added to the Quick Access toolbar. I would summarize the issue by stating that the first time the PopupMenuTool shows its group pane, the keytip letter bubbles are missing. But as long as the group pane does not hide, you can repeat the keystroke sequence and the letter bubbles then appear.
When I create a simple project, I don't have any problem with the keytips, but I am having a hard time tracking down what about the full-blown app is causing the issue. The ribbon toolbar is configured on a Tabbed MDI form.
I was not able to reproduce this issue, but I not clear on the structure of your application. If the ButtonTools are within the PopupMenuTool and the PopupMenuTool is within a RibbonGroup, how can hitting Alt+KeyTip even display the ButtonTools, let alone the key tip bubbles for the ButtonTools? Can you maybe provide a more detailed structure and/or steps to reproduce the issue?
Thanks for the repsonse Mike. I wasn't as clear as I could be. The PopupMenuTool is actually a PopupGalleryTool on the ApplicationMenu's Left panel.
Incidentally, I did manage to isolate the problem. The anomaly happens when the ribbons (UltraToolbarManagers) MenuAnimationStyle is set "Fade".
I have attached a screenshot for your reference. It was created by pressing "Alt+F+S". Note that if you then let up the Alt key, and then repeat the "Alt+F+S" sequence, the letter bubbles appear as they should (not shown):
