A family of Microsoft relational database management systems designed for ease of use.
If you change the RowSource of the Combobox to filter for only Current employees and you have combos on forms that will display non current employees, you will have an issue.
The way I handle this is in the Got Focus event of the combo. By default the RowSource is unfiltered. So when a user views a record, they see the employee assigned to that record. But in the Got Focus event I change the RowSource to a filtered SQL statement, so the user can only select from current employees.
Me.cboEmp.RowSource = " SELECT EmployeeID, Lastname & ", " & Firstname AS Fullname FROM tblEmployees WHERE Current = True ORDER BY Lastname, Firstname;
