You'll have to use VBA code to do this. From Design View:
1) Select all the controls that need to be enabled/disabled.
2) Open the Properties Window, and set the Tag Property (On the Other Tab) to ED (ED is just short for enable/disable. You can set it to whatever you'd like as long as you change ED later in what I suggest to whatever you change ED to in the Tag Property) for every control you want to enable/disable
3) In the On Current Event of the Form, select [Event Procedure] and left click the ellipsis (...) to the right of your selection
4) In the code window, place:
CODE
Dim ctl As Control
For Each ctl in Me.Controls
If ctl.Tag = "ED" and (ctl.controltype = acTextBox Or ctl.controltype = acComboBox or _
ctl.ControlType = acListBox) Then
ctl.Enabled = Me.Active
End If
Next ctl
That loops through all textboxes, combo boxes and listboxes with a Tag Property of ED and enables/disables them according to the value in the field Active.
