wpf - MVVM where to put my class -


i used customized treeviewitem class named treeviewitemwithcheckbox. code copied here treeview checkbox bind different lists

it works fine. question is: mvvm folder should class put into? model, viewmodel, or view?

regards,

since treeviewitem view related function, class part of view. in general, visual "control" should pure view related function.
