c# - Insert rows on a existing dataset -


i have dataset called "titulos" , have 1 table there called "tb" columns name "titulo","titulo 2" , "titulo3". i'm trying insertion of rows in event onclick of button reason code doesn't work! dataset on xsd file , using visual studio 2013 c#. tried code don't know how apply in situation:

northwinddataset.customersrow newcustomersrow =  northwinddataset1.customers.newcustomersrow();  newcustomersrow.customerid = "alfki";  newcustomersrow.companyname = "alfreds futterkiste";  northwinddataset1.customers.rows.add(newcustomersrow);

the problem shows error saying not recognize dataset... erros : "the name " ds_admissibilidade" not exist in current context

a dataset disconnected copy of data. forgets if data originated database, xml file or else. when add rows dataset, change in-memory copy, not original source.

you need mechanism update source. databases, table adapter or dataadapter you. file source, need serialize dataset file, reverse of way read in in first place.
