PropertyGrids Attributes

[TheBerk]

I'm attempting to work with PropertyGrids and C++/CLI for the first time, and I'm having difficullty figuring out how to change the Attributes. I want to change the Category as well as the Descriptions, but the only documentation I can find on this is for C#. According to that I'm suppose to use the [Description] and [Category] attributes before the property, but when I use them in C++/CLI I get attributes not found error. I tried creating these as custom attributes but that didn't effect the grid. Is there another way to do this? Are there different attributes to use? Or is there some special Attributes library I've not included?

Thanks!
