vb.net - Merging Data from Two Bindingsources -


i have 2 binding sources preloaded data 2 database tables @ time program loads(main form load).in particular form,i want use data both tables,i mean data both binding sources(even including duplicates).

there alternative way ,using sql query union both tables , binding control.

but not practical because query return more 150000 rows or more(slows down),that ruin performance of whole system.

so fellows,i looking other way using preloaded data in both bindingsources here also.please suggest me options.
