Save Image Using Ajax.BeginForm in MVC 4

Question

I'm trying to Save Image Using Ajax form. But Unable to Get uploaded image in my action. This is my Index Page, In this page I'm loading partialview for Add Item . My Index.Cshtml

@Html.Action("_AddOrUpdateItem","Admin")

My Action Code

public PartialViewResult _AddOrUpdateItem(int? itemId)
        {
           //Some Code Here 
            return PartialView("_AddItem", item);
        }

        [HttpPost]
        public PartialViewResult AddOrUpdateItem(ToolItem toolItem, HttpPostedFileBase toolItemImage)
        {
           ////Some Code Here
            return PartialView("_AddItem", toolItem);
        }
    }

And My ajax form is as follow

@using (Ajax.BeginForm("AddOrUpdateItem", "Admin", new AjaxOptions() { HttpMethod = "POST" }, new { enctype = "multipart/form-data" }))
{
  // Some more text boxes here
  <input type="file" id="ToolItemImage" name="toolItemImage" />
  <input type="submit" value="Save" />
}

I got a link for this same type of problem , But In my case it is not working

Upload file using Ajax form

Answer 1

在链接中提供了没有附加js脚本的情况下 ，仅使用Ajax.BeginForm加载文件是不可能的，我也无法在您的代码中看到它。无论如何，我强烈建议您使用Jquery Form Plugin来实现此目的。

Answer 2

I dont know ASP MVC but for submitiing a form with file you have to use enctype="multipart/form-data">

so your form must be having something like this

<form action"your controller" method="post" enctype="multipart/form-data">
<input type="file" id="ToolItemImage" name="toolItemImage" />
<input type="submit">
</form>

Save Ajax.Begien Form Image save this Jquery method and also check validation your form using ($("#frmUploader").valid()) this line of code ...

  @using (Ajax.BeginForm("Create", "Employee", new AjaxOptions()
        {
            OnBegin = "startBLoading",
            OnComplete = "stopBLoading",
            OnSuccess = "OnSuccessI"
        }, new { enctype = "multipart/form-data", id = "frmUploader" }))
        {
<div class=row>
..... Enter the Page View Desgine.....

<button type="submit" class="btn btn-product text-capitaliz">Create</button>
</div>
}
<script type="text/javascript">
 window.addEventListener("submit", function (e) {
        debugger

        if ($("#frmUploader").valid()) {
            var form = e.target;
            if (form.getAttribute("enctype") === "multipart/form-data") {
                if (form.dataset.ajax) {
                    e.preventDefault();
                    e.stopImmediatePropagation();
                    var xhr = new XMLHttpRequest();
                    xhr.open(form.method, form.action);
                    xhr.onreadystatechange = function () {
                        if (xhr.readyState == 4 && xhr.status == 200) {
                            if (form.dataset.ajaxUpdate) {
                                var updateTarget = document.querySelector(form.dataset.ajaxUpdate);
                                if (updateTarget) {
                                    updateTarget.innerHTML = xhr.responseText;
                                }
                            }
                        }
                    };
                    xhr.send(new FormData(form)

                    );

                }

            }
            OnSuccessI();
        } else {
            e.preventDefault();
        }
    },

        true
    );
