WPF Validation: Clearing all validation errors?

This is what a BindingGroup is for... You'd set a BindingGroup on a container of all the controls, e.g. The panel that contains them. This would cause the updates to the DataContext to be held until you call UpdateSources on the BindingGroup. If you want to reset the user's input, you'd call CancelEdit instead, and the BindingGroup would reset all controls inside the container to the (still unchanged) values of the DataContext.

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.
