Is there a way to sort an entity collection based on a real type of the object in the collection?

For example, if I have a base class named "vehicle", with "truck" and "car" subclasses - and wanted to group the trucks and cars together in the entity collection (because I'm getting them all based on the base class) - how could I do this?

Is this type of information is lost when switching from a relational model to a the more oo approach with the new llbl (obviously not a LLBLGen specific issue).

Any help is greatly appreciated

I don't think there is a way for you to do this using the entitycollection. You would have to do it on your own.

thanks for the response. I honestly didn't think so. I can't imagine it never comes up though - future feature??

I think you may use your custom comparer

Please check these threads:

Or add a discriminator column to the entity. That field isn't used by LLBLGen Pro as a discriminatorcolumn but you can use it for these situations, so you can sort on that field, which groups them together, you can even do that directly in the query with a sortexpression.
