Overwrite Upload question

[Brian Baker]

Hi, I am using the radUpload in my application.

I have the overwrite option set to false but what I really want to do is to give the user the ability to decide to overwrite it or not.when the file comes back as already existing.
 
I am unsure where the check for existence of the file is done. 

Can someone help with that?

thanks

Hi Brian Baker,

this is not possible for the moment, but it is a good feature to implement it. We are logging it in our system.

Hey,

I am currently looking at being able to prompt the user to Overwrite files, now, I am not sure if this gonna work or not.  And maybe someone could suggest a workaround for it.  Any ways, this is as far as I have gotten.

          private Boolean _overwrite;
        private void radUpload1_FileUploadFailed(object sender, Telerik.Windows.Controls.FileUploadFailedEventArgs e)
        {
            if (e.ErrorMessage.ToLower().Contains("file already exists"))
            {
                e.ErrorMessage = string.Empty;
                ConfirmDialogBox dialog = new ConfirmDialogBox();
                dialog.lblText.Text = "The file " + e.SelectedFile.Name + " already exists.  Would you like to override it?";
                dialog.Closed += new EventHandler(dialog_Closed);
                dialog.Show();
            }
            else
            {
                e.ErrorMessage += Environment.NewLine + Environment.NewLine + "Please contact QuoteIt support personnel.";
            }
        }

        void dialog_Closed(object sender, EventArgs e)
        {
            ConfirmDialogBox dlg = sender as ConfirmDialogBox;
            if (dlg.DialogResult == true)
            {
                _overwrite = true;
                Collection<RadUploadSelectedFile> items = new Collection<RadUploadSelectedFile>();
                foreach (RadUploadSelectedFile file in radUpload1.CurrentSession.FailedFiles)
                {
                    items.Add(file);
                }
                radUpload1.CurrentSession.FailedFiles.Clear();
                //radUpload1.CurrentSession.SelectedFiles.Clear();
                radUpload1.CurrentSession.UploadedFiles.Clear();
                radUpload1.CurrentSession.ValidFiles.Clear();
                radUpload1.Items.Clear();
                foreach (RadUploadSelectedFile file in items)
                {
                    radUpload1.Items.Add(file);
                }
                radUpload1.StartUpload();
            }
        }

        private void radUpload1_FileUploadStarting(object sender, Telerik.Windows.Controls.FileUploadStartingEventArgs e)
        {
            if (_overwrite)
            {
                e.UploadData.OverwriteExistingFiles = true;
                _overwrite = false;
            }
        }

Technically I would have thought this would work, however, once that has been called and after I have clicked on Yes overwrite the file, there is a blank file box inside the RadUpload control container.

So if anyone has any suggestions that would be awesome.

Hi Shaun Sharples,

The reason why you are getting a blank item inside the RadUpload control is because you are adding a
RadUploadSelectedFile object into the Items collection of the RadUpload. Please note that this collection expects an RadUploadItem. What you could do is to get the items from the Items collection before clearing them and re-add them. However, when I tested this, I discovered an issue, which will still not allow you to restart the upload. We could not find a way around this right now and we are currently working on resolving this issue.

Hey Alex,

Oh I see.  Is this a bug of the RadUpload control that you can not add files programatically in this fashion?  Or was it never intended to be able to do it?

Hello Shaun Sharples,

This is not a bug, however there are some additional preparations that you needed to do before uploading the files. For your convenience,however, we have added a new method to the RadUpload- PrepareSelectedFilesForUpload. This method should be called after you add the new files in the SelectedItems collection, to prepare the RadUpload for starting the upload session.

The method will be available with the upcoming internal build.
