Hi guys. Well, thanks for all the useful code. Here is an example of using jqxFileUpload with ASP.NET in C#.

First create a WebService asmx. For this example, It’s called UploadFiles.asmx and the WebMethod is called Upload().
Do note that in my web application I am setting an ID for each user, and storing it in a session variable. I wanted to create a folder for individual users, based on that ID, and upload their own files there:

Client Code:
(JQuery)

 $("#jqxFileUpload").jqxFileUpload({ browseTemplate: 'success',
        uploadTemplate: 'primary',
        cancelTemplate: 'danger',
        width: 300,
        uploadUrl: 'UploadFiles.asmx/Upload',
        fileInputName: 'fileToUpload'
 });

 $('#jqxFileUpload').on('uploadEnd', function (event) {
     var args = event.args;
     var fileName = args.file;
     var serverResponse = args.response;

     $("#spnResponse").html(serverResponse);
 });

(HTML)

<div id="jqxFileUpload"></div><br /><br />
<span id="spnResponse"></span>

Server-Side Code:
(UploadFiles.asmx)
<%@ WebService Language=”C#” CodeBehind=”~/App_Code/UploadFiles.cs” Class=”UploadFiles” %>

(UploadFiles.cs)

....
using System.IO;

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 

[System.Web.Script.Services.ScriptService]
public class UploadFiles : System.Web.Services.WebService {

    public UploadFiles () {

        //Uncomment the following line if using designed components 
        //InitializeComponent(); 
    }

    [WebMethod(EnableSession = true)]
    public string Upload() {
        string appid = HttpContext.Current.Session["appid"].ToString();
        string returnTxt;
        
        if (!System.IO.Directory.Exists(Server.MapPath(@"~/uploads/" + appid)))
        {
            System.IO.Directory.CreateDirectory(Server.MapPath(@"~/uploads/" + appid));
        }

        string filepath = Server.MapPath("~/uploads/" + appid);
        HttpFileCollection uploadedFiles = HttpContext.Current.Request.Files;
        returnTxt = string.Empty;

        for (int i = 0; i < uploadedFiles.Count; i++)
        {
            HttpPostedFile userPostedFile = uploadedFiles[i];

            try
            {
                if (userPostedFile.ContentLength > 0)
                {
                    returnTxt += "<u>File #" + (i + 1) + "</u><br>";
                    returnTxt += "File Content Type: " + userPostedFile.ContentType + "<br>";
                    returnTxt += "File Size: " + userPostedFile.ContentLength + "kb<br>";
                    returnTxt += "File Name: " + userPostedFile.FileName + "<br>";

                    userPostedFile.SaveAs(filepath + "\\" + Path.GetFileName(userPostedFile.FileName));
                    returnTxt += "Location where saved: " + filepath + "\\" + Path.GetFileName(userPostedFile.FileName) + "<p>";
                }
            }
            catch (Exception Ex)
            {
                returnTxt += "Error: <br>" + Ex.Message;
            }
        }

        return returnTxt;
    }
    
}

Hope this is useful for somebody.

Regards,
AJ

Hi Dimitar,

Thank you for your reply. I re-checked everything and found the problem. I was using some of the script files from the previous jqWidgets as I had re-used code from a previous project that used the earlier version of jqWidgets. After replacing jqxbuttons.js from 3.7.0, it started working! Now I feel dumb.

Thanks again 🙂
