Ajax FileUpload & JQuery formData in ASP.NET MVC

Question

I have some problem with posting formData to server side action method. Because ajax call doesn\'t send files to server, I have to add file uploader data to

Answer 1

Instead of Jquery Ajax you could use

 <script>
            function SubmitButtonOnclick()
            { 
                var formData= new FormData();
                var imagefile=document.getElementById("imageFile").files[0];
                var coverfile=document.getElementById("coverFile").files[0];
                formData.append("imageFile",imageFile);
                formData.append("coverFile",coverFile);
                var xhr = new XMLHttpRequest();
                xhr.open("POST", "/Profile/EditProfile", true);
                xhr.addEventListener("load", function (evt) { UploadComplete(evt); }, false);
                xhr.addEventListener("error", function (evt) { UploadFailed(evt); }, false);
                xhr.send(formData);

            }

      function UploadComplete(evt) {
        if (evt.target.status == 200) 
                alert("Logo uploaded successfully.");

        else 
                 alert("Error Uploading File");
        }

    function UploadFailed(evt) {
        alert("There was an error attempting to upload the file.");

    }
 </script>

This works for me !!

Your script with changes

 function SubmitButtonOnclick() {
        var formData = new FormData();
        var file = document.getElementById("imageFile").files[0];
        var file1 = document.getElementById("coverFile").files[0];
        formData.append("imageFile", file);
        formData.append("coverfile", file1);
        $.ajax({
            type: "POST",
            url: '@Url.Action("EditProfile","Default1")',
            data: formData,
            dataType: 'json',
            contentType: false,
            processData: false,
            success: function (response) {
                $('#GeneralSection').html(response.responseText);
            },
            error: function (error) {
                $('#GeneralSection').html(error.responseText);
            }
        });
    }

   <input type="file" id="picfile" name="picf" />
       <input type="text" id="txtName" style="width: 144px;" />
 $("#btncatsave").click(function () {
var Name = $("#txtName").val();
var formData = new FormData();
var totalFiles = document.getElementById("picfile").files.length;

                    var file = document.getElementById("picfile").files[0];
                    formData.append("FileUpload", file);
                    formData.append("Name", Name);

$.ajax({
                    type: "POST",
                    url: '/Category_Subcategory/Save_Category',
                    data: formData,
                    dataType: 'json',
                    contentType: false,
                    processData: false,
                    success: function (msg) {

                                 alert(msg);

                    },
                    error: function (error) {
                        alert("errror");
                    }
                });

});

 [HttpPost]
    public ActionResult Save_Category()
    {
      string Name=Request.Form[1]; 
      if (Request.Files.Count > 0)
        {
            HttpPostedFileBase file = Request.Files[0];
         }


    }
