PropertyGrid incorrect editor for IList of T, T is primitive type?

[daihung]

If I have these properties with item type is primitive type

public IList<int> IListOfInt { get; set; }
public List<int> ListOfInt { get; set; }

PropertyGrid is correctly return 'PrimitiveTypeCollectionEditor' as default editor for List<int>. However, for IList<int>, it returns 'CollectionEditor' as the default editor.

I will thought IList<int> should also use 'PrimitiveTypeCollectionEditor', why not?

Hi,

Thank you for the request. You are right !
This will be fixed in the next release.
In the meantime, if you have the source code for Toolkit WPF, you can go in file
Xceed.Wpf.Toolkit/Core/Utilities/ListUtilities.cs
In method GetListItemType
and replace
var iListOfT = listType.GetInterfaces().FirstOrDefault(
( i ) => i.IsGenericType && i.GetGenericTypeDefinition() == typeof( IList<> ) );
with:
var iListOfT = ( listType.IsGenericType && ( listType.GetGenericTypeDefinition() == typeof( IList<> ) ) )
? listType
: listType.GetInterfaces().FirstOrDefault( ( i ) => i.IsGenericType && i.GetGenericTypeDefinition() == typeof( IList<> ) );

Thank you
