When trying to process the uploaded files for the RadAsyncUploader control I am getting an error "The device is not ready".
Does anyone have any ideas as to what may be causing this?
For Each file As Telerik.Web.UI.UploadedFile In Me.Uploader.UploadedFiles
Dim targetFile = String.Format("{0}\{1}", targetFolder, file.GetName)
file.SaveAs(targetFile)
Next
I am using the latest version of the AsyncUploader control.
targetFile is a validly formed filename and the user has write access to the target folder.
