Good Day All 

I am using the AsyncUpload and locally on my machine it works nicely , i can upload and the status turns "Green" but when i upload on the hosted app , it turns "red" , so the the F12 in console shows me the following 

Uncaught Error while uploading, HTTP Error code is: 500 Telerik.Web.UI.WebResource.axd:3975
a.RadAsyncUpload._onFileUploadFail Telerik.Web.UI.WebResource.axd:3975
a.extend.trigger Telerik.Web.UI.WebResource.axd:4081

Thanks

Hi,

Please make sure that the Telerik.Web.UI.WebResource.axd handler is registered in the web.config properly and also have a look into the following help documentation.

How to register the handle

Thanks,
Shinu.

This has been working on my Dev machine. So i resolved this issue by giving anonymous access to be able to write the Target folder of RadAsync control and it resolved my problem.

Hi everybody, 

To resolve this issue fist of all, I added in the web.config, below code:

 

<system.web.extensions>
    <scripting>
      <webServices>
        <jsonSerialization maxJsonLength="999999999"/>
      </webServices>
    </scripting>
  </system.web.extensions>

      <add verb="*" path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.Upload.RadUploadProgressHandler,Telerik.Web.UI" />
    </httpHandlers>
    <httpRuntime relaxedUrlToFileSystemMapping="true" maxRequestLength="999999999" />

</system.web>


<system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>

Then, open your IIS Manager, click on Application Pools:
Status: Started
.NET CLR Version: v4.0
Managed Pipeline Mode: Integrated (This is the most importan thing)
Identity: ApplicationPoolIdentity

Looks my .aspx page

<telerik:RadAsyncUpload ID="NewDocument_UploadFiles" RenderMode="Lightweight" runat="server"
       MultipleFileSelection="Automatic"
       PostbackTriggers="btnNew"
       DisableChunkUpload="true"
       CssClass="column1">
 </telerik:RadAsyncUpload>
<asp:Button runat="server" ID="btnNew" Text="Save" OnClientClick="return makeSomeValidations();" OnClick="btnNew_Click" />

 

Looks my codebehind 

protected void btnNew_Click(object sender, EventArgs e)
        {
            try
            {
                var currentDate = DateTime.Now;
                string serverPathFile = Server.MapPath("~/" + "Uploads-Folders" + "\\");

                if (!Directory.Exists(serverPathFile))
                    Directory.CreateDirectory(serverPathFile);

                int count = 1;
                foreach (UploadedFile f in UploadFiles.UploadedFiles)
                {
                    var fileExtention = f.GetExtension();
                    var timestamp = DateTime.Now.ToString("yyyyMMddHHmmssfff");

                    var fileNameTimestamp = timestamp + "-" + count + fileExtention;

                    f.SaveAs(serverPathFile + fileNameTimestamp, true);

                    count++;
                }

                // Show User Message
            }
            catch (Exception ex)
            {
                // User Message if getting erros....
            }
        }

 

Now, take a coffe and enjoy that everything is running well.
