System.Exception: RadAsyncUpload does not have permission to write files in the TemporaryFolder. In Medium Trust scenarios, the TemporaryFolder should be a subfolder of the Application Path

I have an application that is using the 2.0 framework and we have tried to use the AsyncUpload.  It works fine on local host but not when it is moved to our test environment.  When we run it we get the error 
System.Exception: RadAsyncUpload does not have permission to write files in the TemporaryFolder. In Medium Trust scenarios, the TemporaryFolder should be a subfolder of the Application Path

I have set the tempory folder to be located in a folder called Filemanger that the original Radupload used with no issues.  I have give Authenticated  user full controll and tried giving everyone full control, which I don't want to do, and still get this error.  I have set UseApplicationPoolImpersonation to true and still the same error.


Also since this is an internal app it has full trust in IIS

Hi Eric,

Please have a look into this forum thread which deals with the same issue.

Thanks,
Shinu.

I have read that thread but it was of no use.  Still get the same error, and the fact that the app pool is in full trust the Medium Trust message is not even applicable. I have the security set IIS_ISRS to have full control and I have added Authenticated User to full control yet this does not seem to help at all.  Why is it that the RadUpload has worked for years yet the AsyncUpload has such issues.

Any resolution to this issue?

The details of the error follow:

Void TestTemporaryFolderPermissions()

RadAsyncUpload does not have permission to write files in the TemporaryFolder. In Medium Trust scenarios, the TemporaryFolder should be a subfolder of the Application Path.

NO I was never able to get this control to work.

I ended up having to add permissions to the folder once I deployed it to the IIS Server and that solved the problem.
