Is it possible to check a form for any empty text boxes rather than having to put a check on each individual text box with an if? Any help would be much appreciated.

I'm not that familiar with WPF, but you might try to get a list of the child-elements in a form, and for each, check if they are of type Textbox. If so, perform your validation.

I have a small wpf/c# application and want to get a list of all of the open views. However, the Application.OpenForms, does not have "OpenForms" in the intellisense (and gives me an error). Could I be missing a specific reference of something?
I have tried: System.Windows.Application.OpenForms;
Based on the docs for the Application class, there is no OpenForms member.

Try Application.Windows
var openWindows = System.Windows.Application.Current.Windows;
