Hi,

I've been trying to change the save location for the uploaded file using the customFileName example but I get the error: 'The given key was not present in the dictionary' on the line string fileRoot = file.UploadRequest.Data["fileRoot"];

The key isn't getting set but I've checked the JavaScript function that sets the key and it is called okay. The client code is:

        function onSessionStarted(data)

        {            

    kw("<%=SlickUpload1.ClientID %>").set_Data("fileRoot", "Uploads");

        }

 

I was playing around with this for hours and couldn't see any reason why it wasn't working so I ran the examples in VS2010 and I get the exact same error with the customFileName example. The version I am using is: 6.1.2.14943 and it is licensed.

Any ideas what might be happening?

Thanks

Simon

Try upgrading to the latest (6.1.4) version -- http://krystalware.com/slickupload/download. 6.1.3 fixed a regression issue with upload data passing in certain browsers that was introduced in 6.1.2.

Let me know if this solves the issue for you.

Hi Chris,

The upgrade did the trick and I can get the values from the keys on the server now in the slickUpload_UploadComplete event but I am still unsure as to how I can change the file location using the value. Your customFileName example doesn't show any server-side code using the passed keys so I assumed that the fileRoot key was automatically used to override the file save location, but I was wrong.

Can you please explain where I can catch the key value on the server and how to use it to override the default save location?

Thanks

Simon

To set the location of an uploaded file, you'll use a custom upload stream provider class. Uploads occur before the page is handled by ASP.NET, so you have to put the filename logic in a separate class that inherits from UploadStreamProviderBase or one of the builtin upload stream providers like FileUploadStreamProvider.

Take a look at Storage\CustomFileNameUploadStreamProvider.cs or Storage\CustomFileNameUploadStreamProvider.vb in the sample project. That overrides the GetServerFileName method to return a filename based on the passed in data. The customFileName upload profile is configured to use that upload stream provider to store files.
