Kendo UI Core - Upload - How to call MVC Controller

I am using Kendo UI Core (Free version) and would like to upload files to Web Server (through MVC Controller). I know the way with paid Kendo UI version but I want to do it with free version of this.

See as below

HTML For Kendo UI Upload

<div class="demo-section k-header">
<input name="files" id="files" type="file" />
</div>


Java Script

$("#files").kendoUpload({
async: {
saveUrl: "save",
removeUrl: "remove",
autoUpload: true
}

});


It adds a button as below:
enter image description here

Now Once I select files I want to upload it to server through MVC Controller.

How I should make a call to MVC controller from here?

Cheers

Answer

For Kendo UI Core(as per your question calling controller action to upload files) :-

$("#files").kendoUpload({
async: {
    saveUrl: "controllername/actionname",    //OR// '@Url.Action("actionname", "controllername")'   
    removeUrl: "controllername/actionname",  //OR// '@Url.Action("actionname", "controllername")'
    autoUpload: true
  }
});

For example if Controller and Action name is Upload and Save for Saving and for removing uploaded files Controller and Action name is Upload and Remove then :-

 $("#files").kendoUpload({
 async: {
    saveUrl: "Upload/Save",     //OR// '@Url.Action("Save", "Upload")'
    removeUrl: "Upload/Remove", //OR// '@Url.Action("Remove", "Upload")'
    autoUpload: true
  }
});

A Small Demo of Kendo file Upload(for kendo ui web) :-

View :-

<form method="post" action='@Url.Action("Submit")' style="width:45%">
    <div class="demo-section">
        @(Html.Kendo().Upload()
            .Name("files")
        )
        <p>
            <input type="submit" value="Submit" class="k-button" />
        </p>
    </div>
</form>

Controller :-

 public ActionResult Submit(IEnumerable<HttpPostedFileBase> files)
    {
        if (files != null)
        {
            TempData["UploadedFiles"] = GetFileInfo(files);
        }

        return RedirectToAction("Index");
    }

 private IEnumerable<string> GetFileInfo(IEnumerable<HttpPostedFileBase> files)
    {
        return
            from a in files
            where a != null
            select string.Format("{0} ({1} bytes)", Path.GetFileName(a.FileName), a.ContentLength);
    }

For Async file Upload :-

View :-

<div style="width:45%">
    <div class="demo-section">
        @(Html.Kendo().Upload()
            .Name("files")
            .Async(a => a
                .Save("Save", "Upload")
                .Remove("Remove", "Upload")
                .AutoUpload(true)
            )
        )
    </div>
</div>

Controller :-

 public ActionResult Save(IEnumerable<HttpPostedFileBase> files)
        {
            // The Name of the Upload component is "files"
            if (files != null)
            {
                foreach (var file in files)
                {
                    // Some browsers send file names with full path.
                    // We are only interested in the file name.
                    var fileName = Path.GetFileName(file.FileName);
                    var physicalPath = Path.Combine(Server.MapPath("~/App_Data"), fileName);

                    // The files are not actually saved in this demo
                    // file.SaveAs(physicalPath);
                }
            }

            // Return an empty string to signify success
            return Content("");
        }

        public ActionResult Remove(string[] fileNames)
        {
            // The parameter of the Remove action must be called "fileNames"

            if (fileNames != null)
            {
                foreach (var fullName in fileNames)
                {
                    var fileName = Path.GetFileName(fullName);
                    var physicalPath = Path.Combine(Server.MapPath("~/App_Data"), fileName);

                    // TODO: Verify user permissions

                    if (System.IO.File.Exists(physicalPath))
                    {
                        // The files are not actually removed in this demo
                        // System.IO.File.Delete(physicalPath);
                    }
                }
            }

            // Return an empty string to signify success
            return Content("");
        }
