    1. COExcellent answer. Could only be more complete if you describe how you arrived at it (where you learned it if not from trial and error) since the MSDN docs make it next to impossible to understand.

    2. COWhat I was wondering about is the use of ImageFormat.Tiff in MemoryStream's Save method - obviously "encoding" done later is a totally unrelated process - i.e. dumping the bytes of the memory stream that was saved using ImageFormat.Tiff into a file will not create a TIFF file, i suppose?

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
