Hi Guys!

I have just recently updated my web application project MVC5 EF6 from kendo 2013.3.1119 to 2013.3.1316 and have noticed default behavior changed when calling ToDataSourceResult  on a EF table value mapped function.
Previously when calling ToDataSourceResult without any  SortDescriptors the order will be applied on first column. But in current version when calling ToDataSourceResult without any SortDescriptors it no longer adds order by first column.

Would like to know if this recent change is a feature or not ?

Cheers!

Hello Cornel,

There are not any changes that we have made to change this behavior. The code remains the same and it looks like this:

            if (!sort.Any() && queryable.Provider.IsEntityFrameworkProvider())
            {
                // The Entity Framework provider demands OrderBy before calling Skip.
                SortDescriptor sortDescriptor = new SortDescriptor
                {
                    Member = queryable.ElementType.FirstSortableProperty()
                };
                sort.Add(sortDescriptor);
                temporarySortDescriptors.Add(sortDescriptor);
            }
 
// where IsEFProvider method looks like this
 
        public static bool IsEntityFrameworkProvider(this IQueryProvider provider)
        {
            return provider.GetType().FullName == "System.Data.Objects.ELinq.ObjectQueryProvider" ||
                provider.GetType().FullName.StartsWith("System.Data.Entity.Internal.Linq");
        }

Hi Petur,

Great but can we bring that code up to date so that it works with EF6 too ?
In EF6 the return type is System.Data.Entity.Core.Objects.ELinq.ObjectQueryProvider.

Cheers!

Hello Cornel,

Yes, we will update our code to reflect the change in the EF provider name. The fix will be available next week.
