I have a Blazor server app which I am using to upload photos. I am attempting to use the Window and Upload components to have a modal dialog.
It is unclear to me from the examples WHEN does the Upload component attempt to call the API Controller. Also, I need to specify exactly where to place the uploaded picture. I have a special folder off the root for photos and folders within that to "group" the photos.
How do I pass the "group" to the controller from the Upload component?
Eventually, this app will be used on tablets and phones and I will want to upload from the device storage OR from the camera. I don't see anything related to that.
