A property of a Control can be bound to a property of Current. a single object named the Current object.You can think of BindingSource as a '2-in-1' data source. Let's start with the typical case: you assign a BindingSource object as the DataSource of a control. So, I did a little experimentation to learn several of the things you can do. There seem to be a variety of different ways to do data binding, but I couldn't find them spelled out anywhere. If you use databases, the DataSource property of your BindingSource is usually a DataSet otherwise, it may be an object of a class in your own application. In the real world, you will probably use a BindingSource object as the the DataSource property of list controls and of Bindings. So, what do these objects have to be? I find the documentation on this subject to be pretty confusing, which is why tutorials like this get written. The BindingSource class also has a DataSource of type Object.The DataSource property of ListBox, DataGridView etc.The Control.DataBindings collection holds Binding objects, each of which has a DataSource property of type Object.Hierarchical data binding with a DataSet.What else can you do with data binding?.NET Compact Framework support for data binding, but I don't know whether everything described here is possible on that platform. Note: In this article, I assume you are proficient in C# (and maybe ADO.NET), but you know nothing about data binding.Дisclaimer: I talk a little bit about. This is not a tutorial for ADO.NET/ DataSets or DataGridView, but see Related Articles. For example, data binding would be useful for implementing an 'Options' dialog box if your options are held in an ordinary. I have the impression Microsoft wants us to use BindingSource instead of older classes such as CurrencyManager and BindingContext, so this article will only help you to use BindingSource.Дata binding can use Reflection, so you're not limited to database tables and rows in ADO.NET DataSets rather, almost any object that has properties will work. NET Framework (and Compact Framework 2.0), you can still do that, but the concept has been extended to other scenarios, to the extent that you can bind almost any property of any control to almost any object. I believe 'data binding' has traditionally referred to automatic synchronization between controls and database rows or tables.

I had a hard time merely figuring out how to use it, so I began to investigate it in the hopes of understanding this mysterious beast. How does it work, exactly? How much can you do with it? There are a lot of people who know how to use data binding, but probably few who really understand it.

The documentation for Windows Forms data binding is pretty sparse. It contains two 'Master-Detail' samples from this article.) Introduction
