Hello Jason Potter,

This is a bug in RadAsyncUpload. I have already logged it into our bug-tracking system and we will fix it in the near future. Meanwhile, the following workaround can be used, hook on the OnClientDeleting event of RadAsyncUpload and use the following code:

function deleting(sender, args) {

var clientStateJson = sender.get_clientState();

var clientState = Sys.Serialization.JavaScriptSerializer.deserialize(clientStateJson);

Array.removeAt(clientState.uploadedFiles, args._rowIndex);

sender.set_clientState(Sys.Serialization.JavaScriptSerializer.serialize(clientState));

}

Best wishes,

Hi There,

Implement the code as suggested but it did not work as expected.

After uploading a file then deleting it and then uploading a different file, when you do a post back I get a file not found error when it gets to the using statement in the following code. It works file if you just upload a single file.

    
            protected void RadUpload1_FileUploaded(object sender, FileUploadedEventArgs e) 
        
                { 
        
                    UploadedImage.Width = Unit.Pixel(250); 
        
                    UploadedImage.Height = Unit.Pixel(200); 
        
                    byte[] imageData; 
        
                    using (Stream stream = e.File.InputStream) 
        
                    { 
        
                        imageData = new byte[e.File.ContentLength]; 
        
                        stream.Read(imageData, 0, e.File.ContentLength); 
        
                    } 
        
                    UploadedImage.ResizeMode = Telerik.Web.UI.BinaryImageResizeMode.Fit; 
        
                    UploadedImage.GenerateEmptyAlternateText = true; 
        
                    UploadedImage.DataValue = imageData; 
        
                }

Any ideas on how to avoid this.

Thanks
Jason

I am having a problem and was wondering if it is related to the same issue. I am using the Ajax Avatar demo as a basis for what I want to accomplish. Every thing works fine with the first file I upload. When I try to upload another file the File_Uploaded event fires for both the first file and the second. A third file fires the event 3 times and so on.

if have implemented the function from the demo

//submit an ajax request to handle the file upload

function fileUploaded(sender, args) {

$find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>").ajaxRequest();

sender.deleteFileInputAt(0);

}

and the workaround you posted above. Still get multiple events firing. I'm trying to get it to just post one file at a time. Same issue?

Hello Ross Barbieri,

The official fix is going to be available with Q2 which is scheduler for the beginning of July. The good news are that we have managed to find out a working workaround and there is no need to use latest internal build. Here it is:

script type="text/javascript">

function clientFileDeleting(sender, args) {

args.set_cancel(true);

var index = args.get_rowIndex();

Array.removeAt(sender._uploadedFiles, index);

sender.deleteFileInputAt(index, true);

sender.updateClientState();

}

</script>

<telerik:RadAsyncUpload runat="server" ID="RadAsyncUpload1" TargetFolder="~/Documents"

OnClientDeleting="clientFileDeleting">

</telerik:RadAsyncUpload>

Please, take a look at the attached project for details.

All the best,
