Hi,
In the application I'm working on, we're using CSLA.NET as the Business Object Framework. In the framework there are a couple of list classes that can be used, 2 of them are: BusinessListBase<T,C> and ReadOnlyListBase<T,C>.
In the UI I have a RadGridView bound to a list. If this list is of the type ReadOnlyListBase, everything works fine. But if I change it to a BusinessListBase, I get the following exception:
I tried a lot of things only to come to the conclusion that this (hopefully) is a bug in the RadGridView.
Any suggestions whether I'm wrong or if this is already known and maybe solved in a new release?
Thanks in advance.

I tried a lot of things only to come to the conclusion that this (hopefully) is a bug in the RadGridView.
Any suggestions whether I'm wrong or if this is already known and maybe solved in a new release?
Thanks in advance.

Hello RVW,
After some research we found out that this actually might be a problem with BusinessListBase's implementation of IQueryable. A fellow developer has described exactly the same problem that you are facing, i.e. everything is fine with the read-only list, but the same OrderBy problem occurs with the BusinessListBase.
The good news is that it appears that this CSLA.NET bug has been resolved in the latest version of CSLA.NET:
"Make LINQ to CSLA work with the Microsoft Dynamic Query library on a BusinessListBase."
