Remarks

The ReferenceConverter is typically used within the context of sited components or a design environment. Without a component site or a usable ITypeDescriptorContext, this converter is of little use.

This converter converts a reference of an object that implements the IComponent interface and displays its properties in the Properties window.

For more information about type converters, see the TypeConverter base class and How to: Implement a Type Converter.

Note

You should never create an instance of the ReferenceConverter class. Instead, call the GetConverter method of the TypeDescriptor class. For more information, see the examples in the TypeConverter base class.

This class provides the IsValueAllowed method to check whether a particular value can be added to the standard values collection. If you do not want to add the value to the collection, override this method.

Notes to Inheritors

Override the IsValueAllowed(ITypeDescriptorContext, Object) method when you do not want to add a value to the standard values collection.
