Provides support for rapid application development (RAD) designers to generate and parse data-binding expression syntax. This class cannot be inherited.
(in System.Web.dll)
Visual Basic (Declaration)

Public NotInheritable Class DataBinder
Dim instance As DataBinder
[AspNetHostingPermissionAttribute(SecurityAction.LinkDemand, Level = AspNetHostingPermissionLevel.Minimal)]

You can use the overloaded static Eval method of this class in data-binding syntax in an ASP.NET Web page. This provides an easier syntax to work with than standard data binding. However, because DataBinder.Eval provides automatic type conversion, it can result in slower performance.
For more information about ASP.NET data binding, expressions, and syntax, see Binding to Databases and Data-Binding Expressions Overview.
The following example uses the static GetPropertyValue method to populate the fields of a Repeater control using an ArrayList of Product objects. The Eval method could be applied with the same syntax, but it would not perform as quickly.
This example assumes the existence of a custom class which exposes a string Model property and a numeric UnitPrice property.
