You can name and apply any attribute you want, and have it contain any data you want, as long as the attribute starts with “data-“.Given that, I added a “data-id” to my DataList options, and included my object id in there.But now I’m running into the problem of retrieving the data-id from the selected value because there is no “selected” or “checked” or other marker on a DataList to tell you which item from the list was selected.
