It will be helpful if you teach me workaround or some hint about following phenomenon.In Windows 11 preview, on the TabbedMdi close button shown as TabCloseButtonLocation.HeaderArea, a dark gray holizontal line is displayed.
The line become thicker on mouse-over the button. The behavior is similar than the scrollbar of Windows 11.The phenomenon occurs in case that PropertyPageSelected is set to TabGroupSettings.TabStyle.(And PropertyPageSelected is indispensable to our application.) Version: NetAdvantage v12.2 and Infragistics_WinForms_20211_SamplesWindows Version: 22000.132 ~ 194, 22454 on Hyper-V / VMWareVisual Studio 2015 (for main use), 2019 (for investigation)Thanks in advance.
Hello and thank you for contacting Infragistics. I tested against Windows 11 22000.194 and I can reproduce this behavior and not on Windows 10. It's an issue with our theme/hot track buttons. You can prevent this by setting SupportThemes to false on the tabbledmdimanager. However at this time we don't have an ETA on Windows 11 support.
Thank you for your support.I can see that the issue is solved in simple application.In relation to that, let me some confirmation:* If there are multiple NetAdvantage components that inhelits UltraControlBase in an application, is it necessary to set SupportThemes=false for all components?* Is there any possibility that other component affect the status of UltraTabbedMdiManager.SupportedThemes?* Is there any possibility that other property than SupportedThemes in UltraTabbedMdiManager (except UseOsThemes) affect the status of SupportedThemes?
