There are a lot of issues here but the main one that's causing your problem is that there is probably a type mismatch between the properties that you are trying to use TwoWay Binding on. You didn't list the code for your Articles property, but I assume it's probably something like IEnumerable.
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.
