The following code example demonstrates how to retrieve a single data record using an ObjectDataSource control and display it in a DetailsView control. The ObjectDataSource control retrieves a specific employee record by calling the GetEmployee method of the EmployeeLogic class. The GetEmployee method requires an employee ID parameter. The ObjectDataSource control uses a QueryStringParameter object in its SelectParameters collection to pass an ID to the GetEmployee method in this example.
To view the example implementation of the EmployeeLogic class and the GetEmployee method, see the ObjectDataSource class overview.
