DataSource Controls :: Cross Server LINQ Associations?

I have some structured objects that map to multiple DB tables that I have created using LINQ using [Association(Name=, Storage=, ThisKey=, OtherKey=)] links to the objects attached to other tables. If I try to create an association to an object attached to a table on another database server, will this throw an error/go horribly wrong (I'm guessing yes)? If this _is_ possible, are there any issues I need to be aware of?

DataSource Controls :: SQL Server Table-valued Function Vs View?

Jul 9, 2010

I would like to know which one is better, table-valued function or View, in terms of perfomance.Earlier I have created view which is performing cross join (which takes time) and 2/3 Left outer join and it's taking time. To reduce execution time I have created table-valued function with parameter to reduce cross join execution time and it returns the same result as view.Just give me an idea about table-valued function and View, in terms of perfomance. Which one is better?

My question is that, for each control the Stored Procedure called or not? If it is yes then it is time consuming and I need to use LINQ to DataSet or LINQ to Object rather than to call SP for each control. What is difference between LINQ to DataSet and LINQ to Object?
