Private Sub btnAssign_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAssign.Click

    'If ListBoxassign.SelectedItem IsNot Nothing Then

    ListBoxall.Items.Add(ListBoxassign.SelectedItem)
    'End If
End Sub

Private Sub btnUnassign_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUnassign.Click
    ListBoxassign.Items.Remove(ListBoxassign.SelectedItem)
End Sub

End Class

The general method is:

Do While (ListBox1.SelectedItems.Count > 0)
    ListBox1.Items.Remove(ListBox1.SelectedItem)
Loop
