Paul Stovell gets development questions and he's not afraid to answer them. "I recieved an email this morning as from Steve Pietrek, a Delphi programmer moving to .NET (great choice Steve!). His question essentially asked how would he go about binding a Windows Forms ComboBox to an enumeration such as this:
public enum CustomerType {
Type1 = 1,
Type2 = 2,
Type3 = 3
}
Fortunately, I figured out how to do this in Trial Balance about a week ago, so I thought I’d share my approach here.

There have been a lot of questions going around about XML and .Net Framework 2.0. Jesse Liberty attempts to answer some of them in his article on the subject: ".NET 2.0 pushes most of ADO.NET into the frameworks level, and provides you with various DataSource controls to make accessing data easy. With the XML DataSource control, you can bind to an XML document just as easily as you bind to tables in a database. If the XML document you load is hierarchical, the data is exposed hierarchically, which makes it ideal to map an XML document to a TreeView
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
