Master Pages Control ID Naming in Content Pages Introduction
All ASP.NET server controls include an ID property that uniquely identifies the control and is the means by which the control is programmatically accessed in the code-behind class. Similarly, the elements in an HTML document may include an id attribute that uniquely identifies the element; these id values are often used in client-side script to programmatically reference a particular HTML element. Given this, you may assume that when an ASP.NET server control is rendered into HTML, its ID value is used as the id value of the rendered HTML element. This is not necessarily the case because in certain circumstances a single control with a single ID value may appear multiple times in the rendered markup. Consider a GridView control that includes a TemplateField with a Label Web control with an ID value of ProductName. When the GridView is bound to its data source at runtime, this Label is repeated once for every GridView row. Each rendered Label needs a unique id value.

Working with Data in ASP.NET 2.0 Handling BLL and DAL Level Exceptions in an ASP.NET Page
Working with data from an ASP.NET web application using a tiered application architecture involves the following three general steps:
1. Determine what method of the Business Logic Layer needs to be invoked and what parameter values to pass it. The parameter values can be hard coded, programmatically assigned, or inputs entered by the user.
2. Invoke the method.
3. Process the results. When calling a BLL method that returns data, this may involve binding the data to a data Web control. For BLL methods that modify data, this may include performing some action based on a return value or gracefully handling any exception that arose in Step 2.
