Why DisplayFor does not post values to Action Method?
asp.net-mvc, asp.net-mvc-2, asp.net-mvc-3, asp.net-mvc-4
Solution
see the html rendering. does not have the attribute `name`. or not an input tag. the form tag only send tag elements `input, select, textarea,...` that have the attribute `name`. For example:
<form...>
<input id="lastname" name="lastname" />
</form>
not this:
<form...>
<input id="lastname" />
</form>
Problem
When we post the form using below to Action Method, we can see the View Model values in Parameter. ``` @Html.EditorFor(model => model.Foo) ``` When we post the form using below to Action Method, we can't see the View Model values in Parameter. ``` @Html.DisplayFor(model => model.Foo) ``` So, in later case, w could us Hidden Fields. So, I think, w should not us `DisplayFor` when it comes o post form values. Question : Why `DisplayFor` does not post values to Action Method? Can we discuss the internal mechanism for this ?
