Data source controls turn up in the .aspx markup portion of your web page like ordinary controls. Here s an example: <asp:SqlDataSource ID="SqlDataSource1" runat="server" ... /> The SqlDataSource represents a database connection that uses an ADO.NET provider. However, this has a catch. The SqlDataSource needs a generic way to create the Connection, Command, and DataReader objects it requires. The only way this is possible is if your data provider includes a data provider factory, as discussed in 7. The factory has the responsibility of creating the providerspecific objects that the SqlDataSource needs in order to access the data source. As you know, .NET ships with these four provider factories: System.Data.SqlClient System.Data.OracleClient System.Data.OleDb System.Data.Odbc These are registered in the machine.config file, and as a result you can use any of them with the SqlDataSource. You choose a data source by setting the provider name. Here s a SqlDataSource that connects to a SQL Server database: <asp:SqlDataSource ProviderName="System.Data.SqlClient" ... /> The next step is to supply the required connection string without it, you cannot make any connections. Although you can hard-code the connection string directly in the SqlDataSource tag, you should always place it in the <connectionStrings> section of the web.config file to guarantee greater flexibility and ensure you won t inadvertently change the connection string, which minimizes the effectiveness of connection pooling. For example, if you create this connection string: <configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0"> <connectionStrings> <add name="Northwind" connectionString="Data Source=localhost;Initial Catalog=Northwind; Integrated Security=SSPI"/> </connectionStrings> ... </configuration> you would specify it in the SqlDataSource using a $ expression like this: <asp:SqlDataSource ConnectionString="<%$ ConnectionStrings:Northwind %>" ... /> Once you ve specified the provider name and connection string, the next step is to add the query logic that the SqlDataSource will use when it connects to the database.

In your code, you re most likely to change settings in the <appSettings> section or the <connectionStrings> section. Here s an example that rewrites the application settings shown earlier so that it updates one of the settings after reading it: protected void Page_Load(object sender, EventArgs e) { Configuration config = WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath); lblSiteName.Text = config.AppSettings.Settings["websiteName"].Value; lblWelcome.Text = config.AppSettings.Settings["welcomeMessage"].Value; config.AppSettings.Settings["welcomeMessage"].Value = "Welcome, again."; config.Save(); }

When the page loads, it retrieves the records from the database and binds them to the list control. This example uses a DataReader as the data source, as shown here: protected void Page_Load(object sender, System.EventArgs e) { if (!Page.IsPostBack) { // Create the Command and the Connection. string connectionString = WebConfigurationManager.ConnectionStrings[ "Northwind"].ConnectionString; string sql = "SELECT EmployeeID, TitleOfCourtesy + ' ' + " + "FirstName + ' ' + LastName As FullName FROM Employees"; SqlConnection con = new SqlConnection(connectionString); SqlCommand cmd = new SqlCommand(sql, con); try { // Open the connection and get the DataReader. con.Open(); SqlDataReader reader = cmd.ExecuteReader(); // Bind the DataReader to the list. lstNames.DataSource = reader; lstNames.DataBind(); reader.Close(); } finally { // Close the connection. con.Close(); } } } The previous code sample creates a connection to the database, creates the command that will select the data, opens the connection, and executes the command that returns the DataReader. The returned DataReader is bound to the list box, and finally the DataReader and the connection are both closed. Note that the DataBind() method of the page or the control must be called before the connection is closed. It s not until you call this method that the actual data is extracted. The last piece of this example is the code for determining the selected items. As in the previous example, this code is quite straightforward: protected void cmdGetSelection_Click(object sender, System.EventArgs e) { Result.Text += "<b>Selected employees:</b>"; foreach (ListItem li in lstNames.Items) { if (li.Selected) Result.Text += String.Format("<li>({0}) {1}</li>", li.Value, li.Text); } } If you want to use a DropDownList, a CheckListBox, or a RadioButtonList instead of a ListBox, you need to change only the control declaration. The rest of the code that sets up the data binding remains the same.

You can use each SqlDataSource control you create to retrieve a single query. Optionally, you can also add corresponding commands for deleting, inserting, and updating rows. For example, one SqlDataSource is enough to query and update the Customers table in the Northwind database. However, if you need to independently retrieve or update Customers and Orders information, you ll need two SqlDataSource controls. The SqlDataSource command logic is supplied through four properties: SelectCommand, InsertCommand, UpdateCommand, and DeleteCommand, each of which takes a string. The string you supply can be inline SQL (in which case the corresponding SelectCommandType, InsertCommandType, UpdateCommandType, or DeleteCommandType property should be Text, the default) or the name of a stored procedure (in which case the command type is StoredProcedure). You need to define commands only for the types of actions you want to perform. In other words, if you re using a data source for read-only access to a set of records, you need to define only the SelectCommand property.

This example reflects the cumulative configuration in the root web application directory, because it uses the Request.ApplicationPath when calling the OpenWebConfiguration() method. If you use the Request.CurrentExecutionFilePath instead, you ll get cumulative settings for the current directory. If the current directory is a subdirectory inside a web application, and if that subdirectory has its own web.config file, you ll see these additional settings.
