Here's a simply workaround/hack. Add a boolean to keep track whether you changed the setting, let's say "IsChangedByMe". When you change the dependency property in code, set the bool to true.
In the ValueChanged event, if IsChangedByMe is true, don't do anything.
If there's a piece of UI databound to that property and you allow for changing the value without triggering the ValueChanged event you'd quickly end up with your UI no longer synchronized with the data.
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.
