There was a similar question asked recently, based on my answer over there I doubt that you can bind the columns itself. To refresh the columns you could subscribe to the PropertyChanged event of one of the items and if the length of the array changes you could rebuild the columns. If the DataContext changes and new items are comming in that way you might also want to handle the DataContextChanged event to refresh.
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.
