Answer 1

Hi I just found this post with the same problem and was able to fix it for me, by setting the Width to the exact width of the header (where the styling stops).

It might not work for you in your context. Also notice this is months old :-)

Answer 2

I was previously having the same issue, updating to the latest version of the grid (WPFToolkit.dll) appears to have fixed this for me
