1. i need pass product name controller. how can ?

i found solution problem.here have paste future help.there's event in dropzone called sending.you can pass additional parameters via append form data.

 dropzone.options.dropzonejsform = {     autoprocessqueue: false,     init: function () {         var submitbutton = document.queryselector("#btnsubmit");         var mydropzone = this;          this.on("sending", function (file, xhr, formdata) {             formdata.append("productname", $("#txtprod").val());           });          submitbutton.addeventlistener("click", function () {         mydropzone.processqueue();          });      } }; 

access in server side

 public actionresult saveproducts(string productname)     {       }
