c# - Order of calling methods -

i'm trying implment file upload feature users can upload multiple files @ once. i'm using dropzone.js on client side , c# in end. i'm using mvc razor views , have view user inputs details , upload files within same page. i've gone ahead , created following methods

[httppost]     public async task<actionresult> uploadedfile(int? id)     {         foreach (string filename in request.files)         {             httppostedfilebase file = request.files[filename];             if (file != null && file.contentlength > 0)             {                 //upload file here                 //file gets uploaded              }         }         return new emptyresult();     } 

i need store model details db done in method follows

public async task<actionresult> savetodb(myviewmodel viewmodel)     {         if (modelstate.isvalid)         {             //store db here              int? id = viewmodel.user.userid;              //redirect home page if ok         }         return view(viewmodel);     } 

now question need run savetodb before uploadedfile method because want pass int? id param because use @ end of file name. can't seem figure out how go this. client jquery looks this:

<script>     dropzone.autodiscover = false;     var mydropzone = new dropzone("#dzupload",{         url: "/home/uploadedfile",         autoprocessqueue: false     });     $("#submit-all").on('click', function () {         mydropzone.options.autoprocessqueue = true;         mydropzone.processqueue();     });     mydropzone.on("addedfile", function (file) {         var removebutton = dropzone.createelement("<button class='btn btn-danger'>remove file</button>");         var dlink = mydropzone;         // listen click event         removebutton.addeventlistener("click", function (e) {             // make sure button click doesn't submit form:             e.preventdefault();             e.stoppropagation();              // remove file preview.             dlink.removefile(file);         });         // add button file preview element.         file.previewelement.appendchild(removebutton);     }); </script> 

note: #submit-all button submits entire form

you dont need define different method uploading, can e done in same post action :

<form action="~/home/savedropzonejsuploadedfiles" class="dropzone" id="dropzonejsform"></form>  <button id="submit-all">submit files</button>  </div>  @section scripts { <script type="text/javascript">      dropzone.options.dropzonejsform = {          //prevents dropzone uploading dropped files         autoprocessqueue: false,          init: function () {             var submitbutton = document.queryselector("#submit-all");             var mydropzone = this; //closure              submitbutton.addeventlistener("click", function () {                  //tell dropzone process queued files                 mydropzone.processqueue();              });          }     };  </script> 

}

now on "savedropzonejsuploadedfiles" action method first handle db saving code upload files.. action method can take model parameter
