I have to develop a customized tab control and decided to create it with WPF/XAML, because I planned to learn it anyway. It should look like this when it's finished:
I made good progress so far, but there are two issues left:
Only the first/last tab item should have a rounded upper-left/bottom-left corner. Is it possible to modify the style of these items, similar to the way I did with the selected tab item?
The selected tab item should not have a border on its right side. I tried to accomplish this with z-index and overlapping, but the results were rather disappointing. Is there any other way to do this?
XAML:
