Hi Stephane,
Thank you for using Syncfusion products.
With the Office2007Style applied to the TabControlAdv, you cannot change its TabBackColor. But you can display the error icon in the tab when its data is wrong and this can be achieved using ImageIndex property of TabPageAdv. Please let me know if this helps you.
