The WinColumnsListEditor serves as the base class for WinForms List Editors that visualize object collections in the form of a grid. In such grids, a row represents a particular object and columns represent the object properties.
The WinColumnsListEditor's members are not intended to be used in your code and are used internally by XAF. To customize the columns displayed by a List Editor for a particular List View, use the Application Model's corresponding Views | <ListView> | Columns node. To learn how to customize the Application Model in code, refer to the Access the Application Model in Code.
