TreeList Editors Module

In XAF applications, you can use tree-like data representation instead of a grid-like one, which is used in a default UI. For this purpose, the eXpressApp Framework supplies the TreeList Editors module. To represent data as a tree, this module uses the ASPxTreeList and XtraTreeList controls. All you need to do to use the TreeList Editors' module's instruments is to implement particular interfaces in your business classes or use ready-to-use classes form the Business Class Library. In addition, you can access TreeList or ASPxTreeList controls in code to customize the default settings or use their features that are not used by default. For details on these controls, refer to the XtraTreeList and ASPxTreeList documentation.
