Lots of routines, or so I think.

[jwcoleman87]

Do complicated forms generally have this many routines?

Is my class abnormally large?

Given the comments in your code, the number of methods seems reasonable. The thing is, in a well architected project, a lot of that functionality shouldn't actually be in the form. You may well need to have a handler for an event of a Button or menu item but that method would then just invoke a method of another object to do the work.

When considering architecture, the Single Responsibility Principle should be something held to the fore of your mind. The responsibility of a form is to provide a point of interface between your app and the user. It's not the form's responsibility to perform complex processing. That should fall to objects purpose built for that single responsibility.

Windows Forms can be a bit kludgy in this regard, which is why WPF was built from the ground up with this in mind. WPF data-binding goes well beyond what Windows Forms offers and makes even event handlers redundant. The MVVM pattern is generally employed in WPF projects where a view model is bound to the UI and data flows automatically between the two. The view model reacts to any changes in the data and performs any first-level processing, passing off anything more complex to other objects built for the purpose.
