This may be related to my recent post regarding not being able to change the BackColor of the TextBoxAdv control as both problems have appeared following the most recent release of the Syncfusion Windows forms components.
The difference here is that changing the TabBackColor using code no longer works. I seem able to change the property using code (checked using Debug.WriteLine) but the color of the tab does not change when running the project.
Is this a bug and is there a workaround as unfortunately I haven't been able to think of one?

Thank you for your interest in syncfusion products,
We regret to let you know that we are unable to reproduce the reported issue on our side. Please have the sample from the attachements and if th issue still exists please provide some additional details regarding the tabstyle you are using and modify the sample to reproduce the issue
Please let us know if you have any other concerns.
I resolved the problem by resetting the TabControlAdv InactiveTabColor. Previously I'd modified this and after the last component update changing a tab's color using code no longer worked. I've modified and attached the sample you provided to illustrate this. In my case resetting the InactiveTabColor of the control works fine as a workaround - I must have altered it at some stage but it no longer matters.
For some reason it now overrides a TabPageAdv's TabBackColor property whereas previously it didn't.
