TcxCustomDBTreeList Class

The base class for the data-aware Tree List control.

Declaration

TcxCustomDBTreeList = class(
    TcxCustomDataTreeList
)

Remarks

This class extends its ancestor class with the DataController property representing an object that manages the connection to a data source. The DataController.DataSource property specifies the TDataSet or its descendant that provides data for the TreeList control. The DataController.KeyField and DataController.ParentField properties identify dataset fields used for building the tree structure. Key field values uniquely identify dataset records (nodes, in the tree structure). The parent field of a record contains the key field value for the record (node), which is the parent of the record (node) within the tree structure.

Data-aware columns are represented by TcxDBTreeListColumn class instances. The TcxDBTreeListColumn class provides the DataBinding property that manages the column’s connection to a data source.
