Eeeek...

You should make your life easier and use ng-show/ng-hide expressions with [span] elements to display/hide content like this. Much easier to deal with than these long expressions...

And... aren't those expressions C# expressions? Angular can only render values from you model and some limited JavaScript. Pretty sure String.IsNullOrWhiteSpace() and TrimEnd() don't exist in JavaScript and even if it did Angular wouldn't understand it because it's limited to a very small subset of JavaScript.
