ListWidth Property Example

The following example uses a SpinButton to control the width of the drop-down list of a ComboBox. The user changes the value of the SpinButton, then clicks on the drop-down arrow of the ComboBox to display the list.

To use this example, copy this sample code to the Script Editor of a form. To run the code you need to open the form so the Open event will activate. Make sure that the form contains:

• A ComboBox named ComboBox1.
  
  
• A SpinButton named SpinButton1 that is bound to a custom number field named SpinButtonValue.
  
  
• A Label named Label1.

Sub Item_Open()
    Set ComboBox1 = Item.GetInspector.ModifiedFormPages("P.2").Controls("ComboBox1")
    Set SpinButton1 = Item.GetInspector.ModifiedFormPages("P.2").Controls("SpinButton1")
    Set Label1 = Item.GetInspector.ModifiedFormPages("P.2").Controls("Label1")

    For i = 1 To 20
        ComboBox1.AddItem "Choice " & (ComboBox1.ListCount + 1)
    Next
    SpinButton1.Min = 0
    SpinButton1.Max = 130

    'convert listwidth value from '122 pt' to an integer
    intpos = instr(combobox1.listwidth," ")
    intwidth = left(combobox1.listwidth,intpos-1)
    SpinButton1.Value = intwidth
    SpinButton1.SmallChange = 5
    Label1.Caption = "ListWidth = " & SpinButton1.Value
End Sub

Sub Item_CustomPropertyChange(byval pname)
    If pname = "SpinButtonValue" Then
        Set ComboBox1 = Item.GetInspector.ModifiedFormPages("P.2").Controls("ComboBox1")
        Set SpinButton1 = Item.GetInspector.ModifiedFormPages("P.2").Controls("SpinButton1")
        Set Label1 = Item.GetInspector.ModifiedFormPages("P.2").Controls("Label1")

    ComboBox1.ListWidth = SpinButton1.Value
    Label1.Caption = "ListWidth = " & SpinButton1.Value
    End If
End Sub
