title: mvc model binding collections on forms, submit only changes?
body: <p>i've seen how to do model binding with asp mvc using collections of objects on a form. how does one submit only changes, a subset of the collection objects, that got changed? (add, delete, change). override the submit with script and somehow roll it yourself ? (to make it easy, lets make the granularity of changes restricted to an object in the collection, ie not down to the object properties).</p>
  
  <p>Thanks </p>
