Not only possible, but a common requirement :-) Welcome to Bytes.com.
In the
_AfterUpdate()
event procedure you would have code that sets the visibility of other Controls (Not Fields exactly - Fields do little more than hold data whereas Controls are a little more complicated.) based on the value found in your other Control.
At a very basic level, if you have a Form (frmX), a ComboBox Control (cboY) and just one TextBox Control (txtZ) to be shown (if cboY = "A") or hidden (if cboY = {anything else}) then you would want code based on this simple template :
- Private Sub cboY_AfterUpdate()
-
Dim blnVisible As Boolean
-
-
With Me
-
blnVisible = .cboY = "A"
-
.txtZ.Visible = blnVisible
-
End With
-
End Sub
