As discussed in Chapter 1, “Getting Started,” the code-behind of pages that use dynamic
controls need to associate the databound control, such as the FormView in this example,
with the MetaTable instance describing the entity class. The MetaTable is typically
retrieved using the MetaModel instance created in the Global.asax and exposed by the
DefaultModel static property, as shown in Listing 4.2.

Customer Information Page (Code-Behind)

using System;
using System.Web.DynamicData;

namespace WebApplication.Samples.Ch04.ReadOnlyTemplate
{

public partial class SamplePage : System.Web.UI.Page
{

protected void Page_Init(object sender, EventArgs e)
{

MetaTable table = Global.DefaultModel.GetTable(“Customers”);
this.form.SetMetaTable(table);

}

}
