Hello,

I have a TypeConverter for converting between this Enum and Strings.

Public Enum DeviceNameEnum
    dnNone
    dn2500
    dnMirror
End Enum 'DeviceNameEnum

The Strings are "None", "2500", and "Mirror". The conversion works in a
PropertyGrid. How can I access the TypeConverter to convert an instance
of the Enum to the corresponding String to put in a TextBox?

Bill,
You can use something like:

Dim converter As TypeConverter =
TypeDescriptor.GetConverter(GetType(DeviceNameEnum))

To get the converter, be certain to review the parameters to GetConverter...

I fixed the problem by also applying the TypeConverterAttribute
directly to the Enum. Previously, the TypeConverterAttribute was only
applied to a public property in a class, which is what makes a
PropertyGrid work.

I understand the property grid looks at the property first, the type second.

So if you put the typeconverter on only the Enum it should work in both
places.

Although I have not tested the above...

I did test it. What you suggest works. The PropertyGrid works if the
TypeConverter is only applied to the Enum, and not to the property.
