Hi, our product supports multiple languages so we use custom classes for the attributes that perform resource lookups, e.g.
public class LocalisedCategoryAttribute : CategoryAttribute { public LocalisedCategoryAttribute( string resourceKey, Type resourceType ) { // use resource manager... } }And in the properties object;
public class LocalisedCategoryAttribute : CategoryAttribute { public LocalisedCategoryAttribute( string resourceKey, Type resourceType ) { // use resource manager... } }
public class FilePropertiesObject { [LocalisedCategory("GeneralCategoryName", typeof( Properties.PropertiesResources ) )] [LocalisedDisplayName("FileSizeDisplayName", typeof( Properties.PropertiesResources ) )] public int FileSize { get; set; } }
This works fine, however it appears impossible to apply this technique to the category sort order. The documentation on CategorySortOrder does mention the argument requirements and there are no name or order properties that can be dynamically returned. We have a custom CategorySortOrderAttribute class and as hinted at in the doco, the constructor is never called. Checking the decompiled IG code it is reflecting on the custom attribute and directly extracting the arguments, never constructing an object.
This causes us to multiply define the sort order for each language, since the category itself is changing.
[CategorySortOrder( "General", 1 )] // English [CategorySortOrder( "Общее", 1 )] // Russian [CategorySortOrder( "通用", 1 )] // Chinese [CategorySortOrder( "Ogólny", 1 )] // Polish public class FilePropertiesObject { [LocalisedCategory("GeneralCategoryName", typeof( Properties.PropertiesResources ) )] [LocalisedDisplayName("FileSizeDisplayName", typeof( Properties.PropertiesResources ) )] public int FileSize { get; set; } }
The drawbacks are that we have to modify the source file whenever the resource changes. Is there a way to localise this information, or could such a feature be considered for an upcoming release?

Hello Logan,
Thank you for the provided snippet code.
I have been looking at your scenario and currently CategorySortOrder attribute does not support localizing of the category name parameter.
What you could do is to create a custom category comparer class that implements IComparer<PropertyGridCategoryItem> where in the Compare method you can specify the general category to be dispalyed as first.
I have attached a sample where XamPropertyGrid's CategorySortComparer property is set to a CustomCategoryComparer class.
