    1. COWhich line is the exception actually being raised on? What does the debugger show for the call stack when the exception is raised? Before the exception occurs, are the `OnRetrievedDir` and `OnDirParseStart` events being triggered? Has the `DirFormat` property being set to a non-empty string by the time the exception is raised? `List()` itself does not do anything that should be accessing any list indexes, so it should be the first access of the `DirectoryListing` property after calling `List()`, as that is when the data captured by `List()` is actually parsed. Can you confirm that?

    2. COI think you are missing `IdFTP1.RetrieveCurrentDir` before `IdFTP1.List`. also try `IdFTP1.List(nil);` without the `FileFilter`. Take a look at: `IndyDemos\FTP`.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
