    1. COI tried this solution but it gave timeout Exception, i tried increasing the Timeout to 2 minute but still the timeout exception is coming whereas in Sql server it takes only 0.01 s. I guess it is making cross join somewhere in LINQ.

    2. COdid you check the generated query by linq and compare with your original query? For me worked so fine. Maybe you need to check your indexes.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
