Hi,

Is it possible to register a user using a TextBox field with validation against a predefined list of nubmers?

The list is numbers between 100 000 and 3 000 000. It's long about 5000 rows. There's no any kind of rule for this numbers. For example:

..so i suppose it's not possible to use regular expressions. The number should be entered in a TextBox field. The DropDown list is not a solution because the user should not know (see) these numbers.

I see only one possible approach:

1) Login as host, go to menu Host -> Lists, add my full list with numbers.

2) Write some kind of validation (i'm not sure if it's possible with regular expressions) against this list. Or some DataColumn.Expression property (like in UTD, FnL) validation or an SQL command (like in Reports).

Any suggestions?
