How To: Display objects in a PropertyGrid DropDown list?

[Steve]

I followed the MSDN example that uses a StringConverter to display states
(like Ohio, Florida,) in a PropertyGrid using a DropDown list. This works
fine for strings, but I would like to do this with objects I create on the
fly.

I think I have to create a custom TypeConverter, but I'm not sure how. Any
examples would be helpful.

Thanks,

Steve

Hello Steve,

You need a custom UITypeEditor, that overrides GetEditStyle, and returns
UITypeEditorEditStyle.DropDown. Then you override EditValue, and have that
function create a custom form of your own creation. Be sure to use a
PropertyDescriptor (via TypeDescriptor) to change the final property, so you
get a designer transaction, and the OnComponentChanging/OnComponentChanged
functions are called automatically for your property.

Look for articles by Shawn Burke, especially the one with "RAD" in the
title, for more info on the property grid.

A very interesting article on the PropertyGrid can be found here:
