We need not write any code to display the control values after they are
bound to these data sources. This kind of data binding allows you to bind
data to the user interface controls without the need to write code.
In its simplest form, the syntax for using data binding in your ASPX pages is
as follows:
<%# Data Source Name %>
Depending on whether you require binding single value data or a multiple or
repeated value data to a control, you can have the following types of binding
mechanisms in ASP.NET data controls:
Single Value Data Binding
Repeated Value Data Binding
Single value data binding, as the name suggests implies, binding of a single value or
a single record, say, an employee's record. In contrast, repeated value data binding
implies binding a set or a table of employee records.
You can use any of the following for single value data binding:
<%# Name of the Property %>
<%# Expression %>
<%# Method Name, Parameter List %>
For repeated value data binding, you can use the following syntax:
<%# Name of the Data Source %>
The following sections presents a discussion on how you can use the data binding
expressions in ASP.NET to bind data to the controls and a discussion on the newly
added data source controls in ASP.NET 2.0 and their usage.

Using the Data Binding Expressions
What are data binding expressions? Well, they are the code snippets that you use
between the <%# and %> blocks in your ASP.
