Linq to SQL

well it's my first post on linq to SQL.
after several days using it.
Hmmm
i found it quite intersesting
By default
it generate's everything(table,storeproc) that u click drag to the dbml
including store procedure(will be come a method in our vs)..

Hmmm.. i'm trying to bind ienumerable to infragistic grid, and it's a mess...
some table display valid some hang out. guess the datatable is the solution for binding or Customized through ultra data source

u can combine with extension or, just add your additional method to your object.
by default linq is optimistic concurrency.
meaning that if on multi user environment,when a user trying to update or delete a row which has been changed by other user it throws exception.
