Refresh combobox after insert a new record EF 4


i have these lines in form_load:

            productscombobox.displaymember = "productname";              productscombobox.valuemember = "productid";              productscombobox.datasource = db.context.products;

when call savechanges on ef, combobox reglect new list.

i tried re-assign context data source of combo box, giving null , assiging agaibn data source, nothing happens.

i know data base saves changes, because when close , re open form, can see new items.

ok, if encounters problem, did initiate database object contained context (ef) after deleting or creating item in db. then, re-assign displaymemeber, valuemember , datasource.

that forced program load again tables, time updated.

but still wierd thing first 1 notice problem.
