How to: Bind a Windows Forms Control to a Factory Object
When you are building controls that interact with data, you will sometimes find it necessary to bind a control to an object or method that generates other objects. Such an object or method is called a factory. Your data source might be, for example, the return value from a method call, instead of an object in memory or a type. You can bind a control to this kind of data source as long as the source returns a collection.
You can easily bind a control to a factory object by using the xref:System.Windows.Forms.BindingSource control.
Example
The following example demonstrates how to bind a xref:System.Windows.Forms.DataGridView control to a factory method by using a xref:System.Windows.Forms.BindingSource control. The factory method is named GetOrdersByCustomerId, and it returns all the orders for a given customer in the Northwind database.

Compiling the Code
This example requires:
- References to the System, System.Data, System.Drawing and System.Windows.Forms assemblies.
For information about building this example from the command line for [!INCLUDEvbprvb] or [!INCLUDEcsprcs], see Building from the Command Line or Command-line Building With csc.exe. You can also build this example in [!INCLUDEvsprvs] by pasting the code into a new project. Also see How to: Compile and Run a Complete Windows Forms Code Example Using Visual Studio.
