You can use a similar approach to add extra parameters. For example, if your method requires a parameter with information that s not contained in the linked data control, just define it as one of the UpdateParameters and then set the value when the ObjectDataSource.Updating event fires. If you re more ambitious, you can even decide to programmatically point the ObjectDataSource to a different update method in the same class: sourceEmployees.UpdateMethod = "UpdateEmployeeStrict"; You ll use this approach to solve a common problem in the section The Limits of the Data Source Controls later in this chapter. In fact, to get really adventurous you could set the ConflictDetection property to ConflictOptions.CompareAllValues so that the old and new values are submitted in the UpdateParameters collection. You can then examine these parameters, determine what fields have changed, and call a different method (with different parameters accordingly). Unfortunately, this isn t a zero-code scenario, and you might end up writing some awkward code for updating and removing parameters. Still, it gives you a valuable extra layer of flexibility.

<asp:ObjectDataSource ID="sourceEmployees" runat="server" TypeName="DatabaseComponent.EmployeeDB" DataObjectTypeName="DatabaseComponent.EmployeeDetails" ... /> Once this is in place, the ObjectDataSource will match only the UpdateMethod, DeleteMethod, or InsertMethod if it has a single parameter that accepts the type specified in DataObjectTypeName. Additionally, your data object must follow some rules: It must provide a default (zero-argument) constructor. For every parameter, there must be a property with the same name. (Public variables are ignored.) All properties must be Public and writable. You re free to add code to your data object class. For example, you can add methods, constructors, validation and event-handling logic in your property procedures, and so on.

Figure 9-3. Data binding with a DataReader The information in this example includes each person s title of courtesy, first name, and last name, which are stored in three separate fields. Unfortunately, the DataTextField property expects the name of only a single field. You cannot use data binding to concatenate these three pieces of data and create a value for the DataTextField. However, you can solve this issue with an easy but powerful trick using a calculated column. You simply need to modify the SELECT query so that it creates a calculated column that consists of the information in the three fields. You can then use this column for the DataTextField. The SQL command that you need to accomplish this is as follows: SELECT EmployeeID, TitleOfCourtesy + ' ' + FirstName + ' ' + LastName As FullName FROM Employees The data-bound list box is declared on the page as follows: <asp:ListBox runat="server" ID="lstNames" Size="10" SelectionMode="Multiple" DataTextField="FullName" DataValueField="EmployeeID"/>

Sometimes you may run into a problem in which the property names of your data class don t exactly match the parameter names of your update method. If all you need is a simple renaming job, you need to perform the task that was described in the Updating with Stored Procedures section earlier, although the syntax is slightly different. First, you define the additional parameters you need, with the correct names. For example, maybe you need to rename the EmployeeDetails.EmployeeID property to a parameter named id in the update method. Here s the new parameter you need: <asp:ObjectDataSource ID="sourceEmployees" runat="server" TypeName="DatabaseComponent.EmployeeDB" SelectMethod="GetEmployees" UpdateMethod="UpdateEmployee" OnUpdating="sourceEmployees_Updating" > <UpdateParameters> <asp:Parameter Name="id" Type="Int32" /> </UpdateParameters> </asp:ObjectDataSource> Second, you react to the ObjectDataSource.Updating event, setting the value for these parameters and removing the ones you don t want: Protected Sub sourceEmployees_Updating(ByVal sender As Object, ByVal e As ObjectDataSourceMethodEventArgs) e.InputParameters("id") = e.InputParameters("EmployeeID") e.InputParameters.Remove("EmployeeID") End Sub

So far, all the examples you ve seen have used parameters to supply values to an update operation. However, you can also create a parameter to return a result. With the SqlDataSource, you can use this option to get access to an output parameter. With the ObjectDataSource, you can use this technique to capture the return value.
