By design, the "Upload" command in the context menu, opens the Upload dialog that will upload a file to the currently selected folder (that is shown in the RadFileExplorer
's addressbar). Indeed, the current implementation of the control requires an item to be left-clicked in order to make the item currently selected one. For the time being, however, we do not plan to change this behavior.
I hope this is not a showstopper for you.
