The Binding Source component can represent any Windows Forms data source and gives you great flexibility when choosing or modifying the location of your data. For more information about the data sources supported by the Data Grid View control, see Data Grid View Control Overview. Introduction A Data Grid View control can be used to display data from a database.A table can be displayed from a database in a Data Grid View, using the Data Adapter class and data logic.There is extensive support for this task in Visual Studio.

Replace the given value with a ' valid connection string for a Northwind SQL Server sample ' database accessible to your system. You can also build this example in Visual Studio by pasting the code into a new project.
All that will do is set all of the Data Rows in the Data Table to Unchanged (and it will remove all Deleted rows from the Rows collection), which means that future calls to the Update method won't see added/modified rows and the underlying database won't get updated.
