I am using ExplorerMode="default". No, there are no failing AJAX requests. All operations work fine. But Treeview doesn't get updated automatically.
Issue is specific to adding/deleting folders. Grid gets refreshed automatically, but not the TreeView on LHS.
Also, there is one more weird thing. While deleting a folder, e.Command is 'DeleteFile' in following event:
RadFileExplorer1_ItemCommand(object sender, Telerik.Web.UI.RadFileExplorerEventArgs e)
However, it is expected to have a value 'DeleteDirectory'. What am I doing wrong here?
