Selecting data is only half of the equation. The SqlDataSource can also apply changes. The only catch is that not all controls support updating. For example, the humble ListBox doesn t provide any way for the user to edit values, delete existing items, or insert new ones. Fortunately, ASP.NET s rich data controls including the GridView, DetailsView, and FormView all have editing features that you can switch on. The first step is to define suitable commands for the operations you want to perform, such as inserting (InsertQuery), deleting (DeleteQuery), and updating (UpdateQuery). If you know that you will allow the user to perform only certain operations (such as updates) but not others (such as insertions and deletions), you can safely omit the commands you don t need. You define the InsertCommand, DeleteCommand, and UpdateCommand in the same way you define the command for the SelectCommand property by using a parameterized query. For example, here s a SqlDataSource that defines a basic update command that updates every field:

<asp:SqlDataSource ID="sourceEmployees" runat="server" ProviderName="System.Data.SqlClient" ConnectionString="<%$ ConnectionStrings:Northwind %>" SelectCommand="SELECT EmployeeID, FirstName, LastName, Title, City FROM Employees" UpdateCommand="UPDATE Employees SET FirstName=@FirstName, LastName=@LastName, Title=@Title, City=@City FROM Employees WHERE EmployeeID=@EmployeeID"> </asp:SqlDataSource> In this example, the parameter names aren t chosen arbitrarily. As long as you give each parameter the same name as the field it affects and preface it with the @ symbol (so FirstName because @FirstName), you don t need to define the parameter. That s because the ASP.NET data controls automatically submit a collection of parameters with the new values before triggering the update. Each parameter in the collection uses this naming convention. To try this, create a page with the SqlDataSource shown previously and a linked GridView control. Now, take the following steps to enable editing: 1. Select the GridView. In the smart tag, choose the Add New Column link. 2. In the Choose a Field Type box, select CommandField. Then, select the Edit/Update check box and the Show Cancel Button check box. Make sure all other check boxes are unchecked. 3. Click OK to add the column with editing controls. When you complete these steps, the GridView editing controls appear in an additional column. When you run the page and the GridView is bound and displayed, the edit column shows an Edit link next to every record. When clicked, this link switches the corresponding row into edit mode. All fields are changed to text boxes (with the exception of read-only fields), and the Edit link is replaced with an Update link and a Cancel link (see Figure 9-10).

Figure 9-10. Editing with the GridView The Cancel link returns the row to its initial state. The Update link passes the values to the SqlDataSource.UpdateParameters collection (using the field names) and then triggers the SqlDataSource.Update() method to apply the change to the database. Once again, you don t have to write any code. You can create similar parameterized commands for the DeleteCommand and InsertCommand. To enable deleting and inserting, you need to add a column to the GridView that has the ShowInsertButton and ShowDeleteButton properties set to true.

Given the wide array of tools available for individual models to customize their behavior, their interaction with the database, and that of the field associated with it, the options are nearly limitless. The techniques that follow represent just a small portion of what s possible.

The GridView is an extremely flexible control. Templates, one of its many features, allow you to define the controls and markup used when editing a record. This is handy if you want to enable editing through drop-down lists, add validation controls, or just fine-tune the appearance of a row in edit mode. You ll learn about templates in 10.
