27 Mar 2008 This tutorial introduces IBM® UniData® and UniVerse® (U2) MultiValue
add-ins for Visual Studio (U2.NET), IBM's new development tool for U2 MultiValue .NET applications.
Develop a U2 MultiValue style master-detail application in C# in Visual Studio 2005.
U2.NET’s Visual Studio integration is demonstrated. Then quickly put together a .NET
purchase order application from a Visual Studio 2005 environment. The demo database
that was installed as part of your standard U2.NET Developer installation is used. Objectives - Create a Windows forms application
- Create an application to browse the U2NETDEMO
file, SALESORDER
- Create three logically connected grids to navigate through
the Sales Order hierarchy in the SALESORDER file
- Use U2.NET's linked data sources capability to extend the logical hierarchy beyond the three levels
- Create a fourth grid control to browse the ORGANIZATION file,
and then link this grid control to the other three you developed in Step 1
Prerequisites
You should be familiar with UniData and UniVerse as well as Visual Studio.
System requirements
In order to use U2.NET, you need to have the following environment:
- Windows XP
- UniData 7.1 or UniVerse 10.2
- Microsoft .NET Framework 2.0
- Visual Studio 2005

Summary minor heading
This tutorial uses Visual Studio 2005 to create a Windows forms application
in two stages. In Step 1, you create an application to browse the U2NETDEMO
file, SALESORDER. The SALESORDER file has a three-level hierarchy of nested data: order, orderlines, and deliveries.
You use U2.NET to create three logically connected grids to navigate through
the Sales Order hierarchy in the SALESORDER file.
In Step 2, use U2.NET's linked data sources capability to extend the logical hierarchy beyond the three levels.
The U2NETDEMO file, ORGANIZATION, holds both customers and suppliers. By using a
select clause (SELECT ORGANIZATION WITH TYPE =
"C"), you can fetch only customers.
Also in Step 2, create a fourth grid control to browse the ORGANIZATION file,
and then link this grid control to the other three you developed in Step 1, to
create a four-level hierarchy that starts with customers and then drills down to
customer orders, order lines, and deliveries.
