  1. If you use the code snippet above, an item in the combobox is a ComboBoxItem and this is why you get it in the setter for Percentage
  2. First of all remove SelectedValuePath="Percentage"

  3. Try removing all the ComboBoxItem declarations, expose the following property from the ViewModel and bind to it ItemsSource={Binding Items}

    public List<int> Items { get { return Enumerable.Range(1, 100).ToList(); } }

  4. Win! :)
