title: How to bind enum to winform combobox using objectdatasource
body: <p>i'm binding a class to a windows form using the object data source: binding simple properties  to textboxes works fine, but i need to bind enum properties to comboboxes too, such as:</p>
  
  <pre><code>    public enum MyEnum
      {
          Val1,
          Val2,
          Val3
      }
      private MyEnum enumVal;
  
      public MyEnum EnumVal
      {
          get { return enumVal; }
          set { enumVal = value; }
      }
  </code></pre>
  
  <p>How to accomplish this using a binding source? I've tried in various ways, but none of these works.
  Thanks</p>
