How to Bind to an ADO.NET Data Source

Posted by on November 3, 2008 No comments

Specific features like accessibility, security, localization, and performance optimization (binding) of the Windows Presentation Foundation (WPF) are best addressed by ADO.NET.

The elements can be bound from various data sources, including ADO.NET, in the form of common language runtime (CLR) and XML.

Creating a Binding
Binding an ADO.NET data follows the following steps;

  1. Specifying the Binding Source
  2. Specifying the Path to the Value
  3. Binding and BindingExpression

Specifying the binding source is done by setting the DataContext property on the DockPanel element, which then inherits the DataContext value from the DockPanel, its parent element.  After specifying a suitable path to the values, a BindingExpression is established. BindingExpression, is the underlying object that helps the maintaining the connection between the ADO.NET data source and the target.

A binding to an ADO.NET contains all the information that can be shared across several binding expressions. Each binding usually has four components, such as binding target, target property, binding source, and a path to the source value to use.

ADO. NET: An Introduction

Data accession is of crucial importance in application development. ADO. NET constitutes a set of computer software components that assists developers to access data and data services. They come as the base class libraries of Microsoft. NET Framework, and help programmers to access and make changes in the data available with relational database systems.

ADO. NET can also be used to access data for non-relational sources.

Benefits of Using of ADO. NET:

Unlike the popular belief that ADO.NET is a derivative of ActiveX Data Objects (ADO) technology, it comprises an array of added features. The extensive change makes is more of an entirely new product.

Comprising two primary subsections, viz., Data Provider and DataSets, ADO. NET offers robust XML support features. It also scores high in the subject of control of data access and behavior and is found to provide well-defined, factored components with predictable behavior, performance and semantics.
