If you have a custom control with a custom property, you can specify a default value for it by using the DefaultValueAttribute. For example: <DefaultValue("")>. This will tell Visual Studio.NET not to serialize the value to the container's code when it is equal to the default value (an empty string in this case). However, if the type of your property is an Enum, you can't just specify the default enum value. You must use an overload to specify the type of the enum and the default value as a string. So use

<DefaultValue(GetType(MyEnum), "MyEnumValue")>

in stead of

<DefaultValue(MyEnum.MyEnumValue)>

Note that both methods work in C#, but only the first one works in VB.NET.
