I had FNCGrid in Unit1 and FNCGridDatabaseAdapter in Unit2. In in this case, the application was unstable, sometimes access violation errors appeared. When I putted FNCGrid and FNCGridDatabaseAdapter in one Unit1 everything works perfectly. Is this a rule that should be followed?
And one more question. My FNCGrid is connected with MS SQL table. During query change (query is closing and opening), contents of the FNCGrid is changing too. Should I deactivate and activate FNCGridDatabaseAdapter at every change? Or BeginUpdate and EndUpdate on FNCGrid will be ok?
