event ValueChanged (ByRef NewValue as Variant)
Occurs just before changing the control's Value.

TypeDescription
NewValue as Variant (By Reference) A Variant expression that holds the new value for the editor.

The ValueChanged event is fired just before changing the editor's Value property. The ValueChanged event notifies your application that the value of the editor is changing. The FindItem property gets the caption associated to a value if the editor contains a predefined list ( DropDownList ).

Syntax for ValueChanged event, /COM version (others), on:

The following sample shows how to restore the old value after user changes the editor's data:

Option Explicit
Dim iChanging As Long

Private Sub Editor1_ValueChanged(NewValue As Variant)
    If (iChanging = 0) Then
        With Editor1
            NewValue = .Value
        End With
    End If
End Sub

Private Sub Form_Load()
    iChanging = 0
    With Editor1
    
        .EditType = DropDownList
        .AddItem 1, "One"
        .AddItem 2, "Two"
        
        iChanging = iChanging + 1
        .Value = 1
        iChanging = iChanging - 1
    End With
End Sub

The following sample displays the newly value:

Option Explicit
Dim iChanging As Long

Private Sub Editor1_ValueChanged(NewValue As Variant)
    With Editor1
        Debug.Print "The user changes the editor's value to " & NewValue
    End With
End Sub

Private Sub Form_Load()
    iChanging = 0
    With Editor1
    
        .EditType = DropDownList
        .AddItem 1, "One"
        .AddItem 2, "Two"
        
        iChanging = iChanging + 1
        .Value = 1
        iChanging = iChanging - 1
    End With
End Sub
