Building and using a 3-tiered data architecture with ASP.NET 2.0

Welcome to a series of tutorials that will explore techniques for implementing these common data access patterns in ASP.NET 2.0. These tutorials are geared to be concise and provide step-by-step instructions with plenty of screen shots to walk you through the process visually. Each tutorial is available in C# and Visual Basic versions and includes a download of the complete code used.

Introduction

Creating a Data Access Layer

In this tutorial we'll start from the very beginning and create the Data Access Layer (DAL), using typed DataSets, to access the information in a database.

Creating a Business Logic Layer

In this tutorial we'll see how to centralize your business rules into a Business Logic Layer (BLL) that serves as an intermediary for data exchange between the presentation layer and the DAL.

Master Pages and Site Navigation

One common characteristic of user-friendly websites is that they have a consistent, site-wide page layout and navigation scheme. This tutorial looks at how you can create a consistent look and feel across all pages that can easily be updated.

Basic Reporting

Displaying Data With the ObjectDataSource

This tutorial looks at the ObjectDataSource control Using this control you can bind data retrieved from the BLL created in the previous tutorial without having to write a line of code!

Declarative Parameters

In this tutorial we'll illustrate how to use a parameter set to a hard-coded value to select the data to display in a DetailsView control.

Programmatically Setting the ObjectDataSource's Parameter Values

In this tutorial we'll look at adding a method to our DAL and BLL that accepts a single input parameter and returns data. The example will set this parameter programmatically.

Master/Detail Reporting

Master/Detail Filtering With a DropDownList

In this tutorial we'll see how to display the master records in a DropDownList control and the details of the selected list item in a GridView.

Master/Detail Filtering With Two DropDownLists

This tutorial expands the master/detail relationship to add a third layer, using two DropDownList controls to select the desired parent and grandparent records.

Master/Detail Filtering Across Two Pages

In this tutorial we'll implement this pattern by using a GridView to list the suppliers in the database. Each supplier row in the GridView will contain a View Products link that, when clicked, will take the user to a separate page that lists those products for the selected supplier.

Master/Detail Using a Selectable Master GridView with a Details DetailView

This tutorial will have a GridView whose rows include the name and price of each product along with a Select button. Clicking the Select button for a particular product will cause its full details to be displayed in a DetailsView control on the same page.

Custom Formatting

Custom Formatting Based Upon Data

Adjusting the format of the GridView, DetailsView, or FormView based upon the data bound to it can be accomplished in multiple ways. In this tutorial we'll look at how to accomplish data bound formatting through the use of the DataBound and RowDataBound event handlers.

Using TemplateFields in the GridView Control

To provide flexibility, the GridView offers the TemplateField, which renders using a template. A template can include a mix of static HTML, Web controls, and databinding syntax. In this tutorial we'll examine how to use the TemplateField to achieve a greater degree of customization with the GridView control.

Using TemplateFields in the DetailsView Control

The same TemplateFields capabilities available with the GridView are also available with the DetailsView control. In this tutorial we'll display one product at a time using a DetailsView containing TemplateFields.

Using the FormView's Templates

Unlike the DetailsView, the FormView is not composed of fields. Instead, the FormView is rendered using templates. In this tutorial we'll examine using the FormView control to present a less rigid display of data.

Displaying Summary Information in the GridView's Footer

Summary information is often displayed at the bottom of the report in a summary row. The GridView control can include a footer row into whose cells we can programmatically inject aggregate data. In this tutorial we'll see how to display aggregate data in this footer row.
