I´m using the repository o data service pattern to acces my datalayer. I have a requeriment to show a dialog with all properties from any entity to make a search. How should be i to build a repository service  to the parameter to the open query to search in the EntityManager?. i.e what should be the type to make the query to the entitymanager?

 

thanks in advanced.

It sounds like you want to build a search query dynamically. If that's the case, the query type should IQueryable. You can see  http://drc.ideablade.com/xwiki/bin/view/Documentation/dynamic-queries - http://drc.ideablade.com/xwiki/bin/view/Documentation/dynamic-queries  for more details.

We also have a few samples that demonstrate how to do repository pattern with DevForce.  http://drc.ideablade.com/xwiki/bin/view/Documentation/mvvm - http://drc.ideablade.com/xwiki/bin/view/Documentation/mvvm

Hope this helps.
