The OpenEdge Ultra Controls for .NET (Infragistics controls) can only be used with .NET Framework. If you want to use Ultra Controls with .NET, you must obtain them yourself. These controls are different from those provided by the Microsoft controls. Ultra Controls allow developers to create forms with sophisticated user interfaces primarily by setting a rich set of properties.

Infragistics provides detailed documentation and help on these controls. While this documentation is written assuming use of a .NET language, the description of a control and its properties and events are all relevant for its use in ABL. You can access this documentation in the following ways:

• Visit the vendor's web site.
• Open the control in the OpenEdge Class Browser to see control definitions using a modified ABL syntax.
• Press F1 after you place the control on the form within Progress Developer Studio for OpenEdge Visual Designer. The online help on the respective vendor site opens.
