Creating a Data Access Layer Creating a Business Logic Layer These concentrate on extending the Table Adapters.Jump over to the code behind, and in the Main cs file, below the closing brace for the class, let’s create a demonstration data class called Demo Class (Example 2) public class Demo Class In the constructor, initialize a collection of these class instances.Based in Brussels, Belgium, U2U Consult has been offering consulting & development services in the EMEA region for over 10 years.In the Cell End Edit event handler, set the Error Text property on the row to the empty string.The Cell End Edit event occurs only when the cell exits edit mode, which it cannot do if it fails validation.Note: We can still add queries or stored procedures to Table Adapters, which become methods we can call (via helper-methods), without having to explicitly extend a Table Adapter.
