Datagridview database not updating

Virtual mode gives you a higher degree of control by allowing you to wait until a cell is actually being displayed to provide the value it will contain.

The following C# source code illustrate how to connect a Data Grid View to a database and new/update or delete the database values from Data Grid View.

But in many cases this only provides a modest improvement as each UPDATE operation still requires a round-trip communication with the database server.

I have never used the Ole Db Data Adapter & Ole Db Command and am not sure what I am doing.

Keep getting this err msg at the high-lighted code, "Object reference not set to an instance of an object".
