Question
You use Microsoft .NET Framework 4 to create a Windows Forms application. You add a new class named Customer to the application. You select the Customer class to create a new object data source. You add the following components to a Windows Form:
- A BindingSource component named customerBindingSource that is data-
bound to the Customer object data source.
- A set of TextBox controls to display and edit the Customer object
properties. Each TextBox control is data-bound to a property of the customerBindingSource component.
- An ErrorProvider component named errorProvider that validates the
input values for each TextBox control. You need to ensure that the input data for each TextBox control is automatically validated by using the ErrorProvider component. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
