Data Binding in .NET Framework

This article gives an overview of data binding in the .NET framework. Microsoft has beefed up the data binding features considerably in .NET which has made data binding a compelling option to tie your front-end to data sources. I have concentrated on .NET windows forms data binding.

What is DataBinding?

DataBinding is a powerful feature provided by the .NET framework that enables visual elements in a client to connect to a datasource such as DataSets, DataViews, Arrays etc. Some of the visual elements in the client can be TextBox, Datagrid etc. A two-way connection is established such that any changes made to the datasource are reflected immediately in the visual element and vice versa.

DataBinding Before .NET

In the earlier databinding models, the datasource that could be used was usually limited to a database. All DBMS systems provided their own API’s to help in building GUI applications and quickly bind them to the data. Programmer did not have the flexibility to control the databinding process with the result that most developers avoided the use of databinding.

DataBinding with .NET

The .NET framework provides a very flexible and powerful approach to databinding and allows the programmer to have a fine control over the steps involved in the whole process. One of the biggest improvements with .Net has been the introduction of databinding to web pages through the use of .Net server-side web controls. Hence, building data driven web applications has been greatly simplified. Please note that this article only deals with data binding in .NET windows forms.

Advantages of DataBinding

1. Databinding in .NET can be used to write data driven applications quickly. .NET data binding allows you to write less code with fast execution but still get the work done in the best way.
2. .NET automatically writes a lot of databinding code for you in the background (you can see it in “Windows Generated Code” section), so the developer does not have to spend time writing code for basic databinding, but still has the flexibility of modifying any code that he would like to. We get the benefits of bound as well as unbound approach.
3. Control over the Databinding process by using events. This is discussed in more detail later in the article.
