This is quite simple...
Define the enum eg:
public enum MyEnum{
ItemOne,
ItemTwo,
}
Within the form set the datasource of the combobox to the values of the enum eg:
myCombo.DataSource = System.Enum.GetValues(typeof(MyEnum));
To have the combo auto select a value based on a bound object, set the databinding of the combo eg:
class MyObject{
private MyEnum myEnumProperty;
public MyEnum MyEnumProperty{get {return myEnumProperty;}}
}
MyObject myObj = new MyObject();
myCombo.DataBindings.Add(new Binding("SelectedIndex", myObject, "MyEnumProperty");
