I have problems when using the multiple file selection of the upload control. There are two problems.
1) I'm having a problem with uploading a large amount of files through multiple file selection. All the checks would appear and then when I try to save all the files on the server, I get the following error.
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
The problem occurs when I select somewhere over 300 files (2MB png files)
2)Another problem is that occasionally multiple file selection is not enabled even though I explicitly enable it in the control.
Any ideas?
