What I've done in these situations is used the XAML hierarchy to determine which element to show/hide. Something along the lines of.
The ideal way to do this would be to create a ClickEditableTextBlock control, which by default renders as a TextBlock but shows a TextBox when the user clicks it. Because any given ClickEditableTextBlock has only one TextBlock and one TextBox, you don't have the matching issue. Then you use a ClickEditableTextBlock instead of separate TextBlocks and TextBoxes in your DataTemplate.
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.
