How do I get rid of the red rectangle when my wpf binding validation has failed and the containing panel is no longer visible?

If I remember correctly, this is a known issue. We re-templated textbox to include the following.

I have an answer to the problem myself which is to change my button click event which changes the visibility of the panels. This would change to something like this.

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.
