Remarks

Use this class as a base class for deriving controls to render specific types of choice fields on forms (but not on list views).

Objects of the BaseChoiceField type are primarily used as the value of the SPField.FieldRenderingControl property.

A control derived from the BaseChoiceField type can also have a text box in which the user can type a custom value.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
