Hi Monika,

Thanks for the help, It is still work in progress.. I have another issue that I need to resolve,  It is somehow related to the way control operates.. After I've read the stream ( string xmlDt = impOS.ReadLR4OneSourceSpreadsheet(e.FileStream); ) I do some data save and then has to seamlessly transfer to other page that does processing and representation.. The upload control while sending file to the server does not cause page to postback... so there is seems like no lifecycle page events where I can put Server.Transfer request and naturally if I would put it into UploadFinishing event like below I will get {"Error executing child request for Uno.aspx."}, because it is apparently wrong context.. Would you advise how to deal with transfer in the WebForm environment while using this control for Upload.. The transfer is needed right after file read in the  UploadFinishing event.. 

protected void WebUpload1_UploadFinishing(object sender

, nfragistics.Web.UI.EditorControls.UploadFinishingEventArgs e)
{
LR4OneSourceImport impOS = new LR4OneSourceImport();
string xmlDt = impOS.ReadLR4OneSourceSpreadsheet(e.FileStream);
// e.Cancel = true;
Server.Transfer("Uno.aspx", true);
}

Thanks.

Hello Michael,

It looks like there is some issue with the FileUploading event and it fires twice. You can workaround that by using a boolean var that shows if you've already handled it for this cycle like this:

 var uploadingFlag = false;
        function WebUpload1_FileUploading(eventArgs, infoObject) {
            if (uploadingFlag) {
                uploadingFlag = false;
                return;
            }
            uploadingFlag = true;
            if (!confirm("Continue will override existing data")) {
                return false;
         }
}

I've logged the issue in our internal system with ID 272025 and created a private support case on your behalf - CAS-210596-J0S1Y5. I've linked the issue with your case so that you will receive updates about its development.  

Regarding the second question - there are icons in these places. My assumption is that they are not available because you are missing some part of the css folder structure. Please, ensure that you've copied the entire C:\Program Files (x86)\Infragistics\2020.1\ASP.NET\jQuery\css directory to the directory you are referring in your app.

As for the progress updates - you've already defined a http handler in your web.config so you may add it as a progress URL - ProgressUrl="/WebUploadStatusHandler.ashx". Please, check if that solves the issue.

I hope this helps! Please, let me know if I may help you further!

Best regards,

I guess if nothing else, like attach somehow click event to the uploadStart button (2nd phase), I can put confirm to FileSelecting event.. 

Hello Michael,

I am sorry for the delayed response!

I had to dig in a bit deeper  but you are right, the FileUploading event cannot really be used to cancel uploads on user request as it is fired during the uploading progress, after the request has already been made. It could work for larger files where the user has some time to decide but it's overall better to use FileSelected.

Alternatively, if FileSelected doesn't meet your UX requirements, I can create a workaround hijacking the click event on Upload button so that you can hook to it. Let me know if you prefer that.

Best regards,

FileSelecting

Hi Stamen.. FileSelected works fine. Thanks for your help.
