I'll take the liberty of suggesting you use a custom control of my own invention. It's called a ProportionalPanel and it does just what you need - spaces items evenly. You could use it for the ItemsPanel in the inner ListBox instead of the StackPanel.
I also provide the source code, so you can tweak the logic any way you like. The relevant post on my blog is here .
I think the proportional sizing operator will do what you're looking for. Haven't tried it but it sounds like an option. Width="*" and Margin="2*".
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.
