Data Columns are used to display and edit data. These columns represent fields in the ASPxTreeList's data source. Their TreeListDataColumn.FieldName properties refer to valid fields in the data source.
Since different types of data columns represent different types of data, they provide their own editors. For example, Boolean values are edited using a check box editor, while DateTime values are edited using a DateTime editor. To access and customize the column editor's settings, use the TreeListDataColumn.PropertiesEdit property.
