I have a listbox which has multiple selection enabled, I have a combo box on the form and I would like that to be populated by those selected in the listbox.

so if I select the first item in the listbox the combo gets updated to include that item, when another item is selected then the combo gets that row added.

Not sure which event to use

I have this code:

 For Each Item In ListCW.SelectedItems
                    If Not String.IsNullOrWhiteSpace(Item) Then
CBCWSelectedItems.additem Item.ToString()
                    Else
                        'do nothing whitespace
                    End If
                Next

Hi Peter;

If the items in the ListBox are of type String then the following code should do what you need. If they are complex objects then the code will need to be modified.
Private Sub ListBox1_SelectedValueChanged(sender As Object, e As EventArgs) Handles ListBox1.SelectedValueChanged

    ComboBox1.Items.Clear()
    Dim items = ListBox1.SelectedItems.OfType(Of String).ToArray()
    ComboBox1.Items.AddRange(items)

End Sub
