"Datareader is faster but dataset is better for bind to controls" - ok, but as a whole : create the datareader + parse and add to datagrid versus create the dataadapter+fil l the datatable and add to datagrid which is faster?

Hy ! I'm at the begining of an application. I have a module with a datagrid/listview (not sure yet) in wich I display data. I insert, update, delete only one row at a time in only one table. I can use a datatable from a dataadapter.fil l() and bind datagrid to datatable. OR I can use a datareader from an comm.ExecuteRea der() and add rows to listview/datagrid. I want speed for my application. So which is better an faster: from datadapter or from executereader?...
