Hi,
can't view the image you have provided, but I know the one you refer to....the Style Builder Dialog Box. I may be wrong here but I don't think you have acces to it. And for the life of me, I can't find the namespace in which it may be contained.
The closest is: " <Editor(GetType(StyleCollectionEditor), GetType(UITypeEditor))>" which you can use for a property of type
CssStyleCollection but this will allow you to set the style for an object, such as a server control. That being said, I think the Style Builder you refer to is applicable to HTML block or inline elements such as DIV and SPAN elements,
that is why in design, when you click on a div or span element, you see the
style in the property grid.
I haven't read the article fully, but check out:

If I am wrong, and you do find a work-around, please let me know.
