MultiBinding not working but corresponding Binding does work?

May be you should try to add any temporary unused bound value. For instance.

I know this is a bit old, and you have likely figured this out by now, but I came across this as I had a similar problem and thought I'd share the solution: I had the same problem and have added the attributes ElementName and Mode as below.

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.
