Remarks

A CategoryAttribute indicates the category to associate the associated property or event with, when listing properties or events in a property grid control set to Categorized mode. If a CategoryAttribute has not been applied to a property or event, the property grid associates it with the Misc category. A new category can be created for any name by specifying the name of the category in the constructor for the CategoryAttribute.

The Category property indicates the name of the category that the attribute represents. The Category property also provides transparent localization of category names.

Notes to Inheritors

If you use category names other than the predefined names, and you want to localize your category names, you must override the GetLocalizedString method. Additionally, you can override the Category property to provide your own logic for localization.
