Suppose we have below enum which we want so show as data source in Combbox,
public enum UserDefinedEnum
{
String = 1,
Numeric = 2,
Currency = 3,
Decimal = 4,
DateTime = 5,
ValidValues = 6,
}We will set this as data source using below code. comboDataType.DataSource = Enum.GetNames(typeof(UserDefinedEnum));
