When you work with combo boxes de ned for data entry, the purpose of the list of types is to provide a set of choices for a speci c business object property Before you can complete the binding, you need to de ne that business object property For example, for a Product Type combo box, the selected product type must be retained with all the other Product object properties This requires that you create a ProductType property in the Product class and that you bind that property to the user-selected value from the combo box To de ne a property in the business object class for the combo box selection: 1 Add a property in the business object class Use the same style of Property statement used for the other properties in the business object classes For example, a ProductType property is de ned as follows:

You now have the list of valid values to display in the combo box, using either a collection class or a DataTable You also have a business object property to assign the value that the user selected from the list The last step is to set up the binding To set up the binding for a data entry combo box: 1 Create an object data source for the class that manages the list of valid types If you are using a collection class, this is the collection class If you are using a DataTable, this is the class de ned to manage the DataTable In either case, the name of the class was de ned as TypeList The result is shown in Figure 715
