you use {binding ...} everywhere in cell templates, bindings twoway default, user input would/should automatically passed underlying data objects. however, don't see binding on listview.itemssource property, forgot prepare dataobjects. create collection of dataitems, bind them itemssource, let listview display them , celltemplates bindings should update dataitems' properties no work side. when submit pressed, check collection of dataitems, data entered should there (assuming made models , bindings properly).
