To be honest, I'm really not sure what the actual problem is here; the VirtualizingStackPanel is still in the visual tree, but it seems that none of the items actually added. Enough of the bad news, the good news is I've found a way to work round it, by changing the default style of the ScrollViewer to place the header there instead, which results in two styles that look like this.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
