Remarks
At run time, the CustomPropertyToolPart looks for the ResourcesAttribute class. If found, the CustomPropertyToolPart iterates through the LoadResource method (you must override this method) with the resource values from the ResourcesAttribute. If the resource cannot be found, the CustomPropertyToolPart user interface is built with the default values. Otherwise, the CustomPropertyToolPart user interface is built with the localized values. The Microsoft .NET Framework will only provide localization values for the Property label, descriptions, and Category label. The base property name will not be localized. If the ResourcesAttribute class isn’t defined, the CustomPropertyToolPart user interface will revert back to the non-localized metadata (that is, CategoryAttribute, DescriptionAttribute, FriendlyNameAttribute, and the internal name of the property).
Examples
The following code example demonstrates how to localize your custom property when displayed in the CustomPropertyToolPart user interface.
