The easy one is probably to make two independent connections to the  
database. More elaborated solutions would be for example copy all said  
records to a memdataset and only connect that to a dbgrid, OR put the  
records in a non-dataset enabled component, like a TDrawGrid or  
TStringGrid, browsing that will not trigger any dataset events so other db  
controls will be unaffected, etc. The problem here is I think  
synchronizing stuff, you will have a funny time getting the updates to  
those records into the original source.
