All I want to do is to have a form with these fields including file upload. But Im confused because of having 2 submit buttons (1 for upload and 1 for form submition)I want to validate the fields and then save them and the uploaded file as an order in the db. How can I omit the fileupload helper’’s upload button and use my own submit?

推荐答案
You can have multiple submit buttons for the same form, but nesting forms is not allowed in html. If you look at the generated code, you will see, that this helper will generate a form. Be aware, that originally it was built for asp.net web forms, not for web pages nor mvc.
SetincludeFormTag:falsein@FileUpload.GetHtml(see: http://evonet.com.au/webmatrix-uploading-images-with-the-fileupload-helper/[^]), so your outer form will post the file input field also.
