I am designing a ListX form where a number of records (i.e. List Item Detail rows) are displayed each with a checkbox. The user checks one or more of them and then clicks a button in the header. This triggers an action that should set a flag on the records that were checked.

The question is - how can I pass the set of records that were checked into my SQL update? If I could pass a string containing the IDs of the records, for example '3,7,10,23' to the action, I could write a stored procedure that parses the string and updates the relevant records.

Any suggestions?

Hello lneville,
You can do this very easily by naming all of your checkboxes the same thing.
Thanks,

Could you explain a bit further? Are you suggesting I give them all the same name, e.g. frmFlag, then create a mapping of frmFlag->@Flag in Variables? What would @Flag contain then?

That would give you a comma separated list of values. You can always output the result of this through a value of [frmFlag, Form] to the screen to see exactly what it looks like.
Thanks,

Excellent! Thanks.
