Hi Josepth Badrouk,
We’ve prepared a sample to help you achieve your requirement of disabling or customizing the Ctrl+Tab behavior in the TabControl.
In this sample, we’ve used the PreviewKeyDown event to intercept the Ctrl+Tab key combination and prevent the default tab navigation. Additionally, we've included an optional customization where you can use an alternate key combination (e.g., Ctrl+T) to manually switch tabs.
Please refer to the attached sample and let us know if it meets your needs or if you require any further assistance.
Regards,
Sekar Sivalingam
