c# - Viewmodel always null following file upload -


i creating page in asp.net mvc user can upload file, along details file textboxes.

for use viewmodel, , simple method configuration. page populated correctly [get] method, , user can choose file , enter details, once 'submit' button clicked, , [post] method called, viewmodel null.

i have done research on , have tried:

  • adding enctype="multipart/form-data"
  • simply using file separate parameter

to no avail.

here controller methods:

public actionresult filecomment(int id) {     //set [get] view      return view("filecomment", obj); }  //this method's viewmodel null [httppost] public actionresult filecomment(calibrationcommentviewmodel file) {     //save file database      return view("edit", new { id = file.id }); }

here part of view:

@using (html.beginform("filecomment", "calibration", formmethod.post, new { enctype = "multipart/form-data", @data_ajax = "false" })) {     @html.hiddenfor(m => m.id)     <div class="container">         <h4>add file @model.id</h4>         <hr />         <div class="row">             <div class="col-md-1">g                 @html.labelfor(model => model.file, htmlattributes: new { @class = "control-label" })             </div>             <div class="col-md-2">                 @html.textboxfor(model => model.file, new { type = "file" })             </div>             <div class="col-md-9"></div>         </div>         <br />         <div class="row">             <div class="col-md-1">                 @html.labelfor(model => model.attachmenttype, htmlattributes: new { @class = "control-label" })             </div>             <div class="col-md-2">                 @html.dropdownlistfor(model => model.attachmenttype, model.attachtypelist, new { @class = "form-control" })             </div>             <div class="col-md-9"></div>         </div>         <br />         <div class="row">             <div class="col-md-1">                 @html.labelfor(model => model.date, htmlattributes: new { @class = "control-label" })             </div>             <div class="col-md-2">                 @html.editorfor(model => model.date)             </div>             <div class="col-md-9"></div>         </div>         <br />          <div class="row">             <div class="col-md-1">                 @html.labelfor(model => model.description, htmlattributes: new { @class = "control-label" })             </div>             <div class="col-md-2">                 @html.textareafor(model => model.description, new { cols=35, @rows=3})             </div>             <div class="col-md-9"></div>         </div>          <br />         <div class="row">             <div class="col-md-1"></div>             <div class="col-md-2">                 <button type="submit" onclick="javascriptfunction()">add @model.id</button>             </div>             <div class="col-md-9"></div>         </div>      </div> }
