First one has the desired affect - change text in textbox and the content of the label changes whereas the second one doesn't. Why? Wpf 2-way-object-databinding link|improve this question asked Jun 30 '11 at 16:06Vishal Saxena61.

These two work: You need to bind to the correct property on the correct item. In the top case, you bount the label to its own Content property... oops.

Sorry for my typo, must be watching Wimbledon at the time of asking. What I meant to ask was what you have written out clearly without the UpdateSourceTrigger attrib. Remove it and you will see that upon changing the target textbox text the content of the source label doesn't change.

So Default trigger for Source – agent-j Jul 1 '11 at 16:12.

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.
