TopIndex property example

  • Article

The following example identifies the top item displayed in a ListBox and the item that has the focus within the ListBox. This example uses the TopIndex property to identify the item displayed at the top of the ListBox, and the ListIndex property to identify the item that has the focus.

The user selects an item in the ListBox. The displayed values of TopIndex and ListIndex are updated when the user selects an item or when the user clicks the CommandButton.

To use this example, copy this sample code to the Declarations portion of a form. Make sure that the form contains:

  • A Label named Label1.
  • A TextBox named TextBox1.
  • A Label named Label2.
  • A TextBox named TextBox2.
  • A CommandButton named CommandButton1.
  • A ListBox named ListBox1.
Private Sub CommandButton1_Click() 
 ListBox1.TopIndex = ListBox1.ListIndex 
 TextBox1.Text = ListBox1.TopIndex 
 TextBox2.Text = ListBox1.ListIndex 
End Sub 
 
Private Sub ListBox1_Change() 
 TextBox1.Text = ListBox1.TopIndex 
 TextBox2.Text = ListBox1.ListIndex 
End Sub 
 
Private Sub UserForm_Initialize() 
 Dim i As Integer 
 
 For i = 0 To 24 
 ListBox1.AddItem "Choice " & (i + 1) 
 Next i 
 ListBox1.Height = 66 
 CommandButton1.Caption = "Move to top of list" 
 CommandButton1.AutoSize = True 
 CommandButton1.TakeFocusOnClick = False 
 
 Label1.Caption = "Index of top item" 
 TextBox1.Text = ListBox1.TopIndex 
 
 Label2. Caption = "Index of current item" 
 Label2.AutoSize = True 
 Label2.WordWrap = False 
 TextBox2.Text = ListBox1.ListIndex 
End Sub
