@enchev, That's so cool! I tried for years to get MSFT to implement Dynamic Linq Library in LightSwitch. Passing expressions as text is so much easier. Hmmm I wonder if we can do plain text like:
.Where("Id = 3 OR UserName = "%SomeProperty%"")
Thanks for the quick response. Now if only RadZen had the ability to model querys on entities in the dataservice.
