What error yo got?
When I tried to select 1897 files at once, then there is no "ShowProgressBar" and no uploads takes place. I renamed the 1897 files to minimal filename and the upload is in progress.
If get the file name to long message, it is the windows system limitation, is not a bug.
How can I convey the same message to the user at runtime if the file upload cannot take place due to this limitation?
I observed that "WindowsDialogLimitMsg" property has value "Unable to select so many files at once. The total file name length cannot exceed 32kb.".
Do I need to use "WindowsDialogLimitMsg" property? If so, how to use it?
