Is there any way to create a column in any sharepoint list that accepts
unique values only. For instance, if I have a column/filed by the
name "Employee No.", and if I enter EmployeeNo = 3 and save the record,
the list should not allow anyone to re-enter a record with employee no
3, as the record for that employee no. already exits.
What say guys? Like these small but interesting challenges in
sharepoint..
