}

you create separate action in controller handle post action, "postback" webforms. handle items in post have handled in postback.

if you're handling validation, sure check modelstate.isvalid , homecoming model view 1 time again should display validate errors

public actionresult edit() { var model = new editmodel() { id=guid.newguid() }; homecoming view(model); } [acceptverbs(httpverbs.post)] public actionresult edit(editmodel model) { if (modelstate.isvalid) { // stuff when valid homecoming redirecttoaction("index"); //or whatever when you're done saving, etc... } homecoming view(model); }

in view:

@html.hiddenfor(x=>x.id);
