Why do I still see the home page content when I enter iPortal even though I've unchecked the home page from the navigation settings?

The base map is Tianditu, and the overlay is a map composed of grid surfaces. I want to achieve an effect where clicking on a grid can obtain detailed information about this grid. Is there such an event?

I publish a workspace using iDesktopX (the workspace is stored on my local computer). If I delete this workspace later, will it affect the service?
