What is the Visual Basic syntax to disable a field in form if a certain option is selected from a list box?

Question

I have a list box that has 2 options: PSF & QTC. If PSF is selected, I want the Network field to be disabled. If QTC is selected, I want the Sales Order to be disabled. Can someone help me with the syntax?

Answer 1

If List1.ListIndex = (whatever position your item to cause the disabling is) Then
txtNetwork.Enabled = False
Else:
txtNetwork.Enabled = True
End If

Answer 2

Private Sub List1_Click()
If List1.text = "PSF" Then

,network field disaabled code here
exit sub
End If

If List1.text = "QTC" Then

,Sales Order disaabled code here
exit sub
End If

End Sub

Answer 3

assuming the network 'field' is a textbox, it's simply

If Listbox.selecteditem = "PSF" then
TextboxNetwork.enabled = False
End If

Answer 4

Here is a snippet.............

Private Sub Form_Load()
List1.AddItem "aa"
List1.AddItem "bb"
End Sub

Private Sub List1_Click()

If List1.Text = "aa" Then
Text1.Enabled = False
Else
Text1.Enabled = True
End If
End Sub

Answer 6

For VB.NET you can have a click event and then just do field.enabled = false; in your codebehind.

If you were meaning vbscript...well you can do it in javascript in a similar way by doing document.form.field.enabled = false; in the onclick function of the field.

Answer 7

The me keyword refers to the current form. You need to add this code on the change event (I think) of the options

If me.PSF = true then
me.networkfield.enabled =false
end if

If me.QTC = true then
me.salesorderfield.enabled = false
end if
