I have a solution in which I have created a file upload with the file explorer in a Rad Window as per one of your tutorials. The tutorial works but my solution does not. Can someone see what I have missed.
The provided code is correct and I am not quite sure what my cause the problem on your side. Could you please provide me more information about the error that you experience? It will be best if you open a new support ticket and send me the project that reproduces the problem. I will check it and do my best to provide a solution as soon as possible.
