How to do a ASP.NET MVC Ajax form post with multipart/form-data ?

Question

I am working on a ASP.NET MVC web site which has a form that allows for the upload of files using the multipart/form data enctype option on the form tag like so

<form enctype="multipart/form-data" method="post" action='<%= Url.Action("Post","Entries",new {id=ViewData.Model.MemberDetermination.DeterminationMemberID})  %>'>

How would I write this to do an ASP.NET MVC Ajax form post instead?

Answer 1

The jquery forms plugin supports file uploads in this way.

Answer 2

I actually answered the question myself...

<% using (Ajax.BeginForm("Post", "Entries", new { id = ViewData.Model.MemberDetermination.DeterminationMemberID }, new AjaxOptions { UpdateTargetId = "dc_goal_placeholder" }, new { enctype = "multipart/form-data" }))

Answer 3

1. You can use some additional uploaders (e.g. jQuery multiple file uploader) (I prefer this way and I prefer not to use MS Ajax)
2. Use AjaxHelper.BeginForm("Post", "Entries", new {id=ViewData.Model.MemberDetermination.DeterminationMemberID}, new AjaxOptions(){/some options/}, new {enctype="multipart/form-data"} )
   But in second case I'm not sure that it will work.

Answer 4

If i use the Ajax.BeginForm() Along with

It is not working ?it working with HTML.BeginForm()Why ?

Answer 5

<% using (Ajax.BeginForm("Post", "Entries", new { id = ViewData.Model.MemberDetermination.DeterminationMemberID }, new AjaxOptions { UpdateTargetId = "dc_goal_placeholder" }, new { enctype = "multipart/form-data" }))

I tried this as you posted but it won't work! The files are not send via ajax! only the form info is sended but not the files :(
