                                This example demonstrates how to use DataTable with the master-detail relationship in TreeList

                                The XtraTreeList control provides different mechanisms (Data Binding Modes) to display data.
                                When DataTable is assigned to the TreeList DataSource property (Bound Mode) TreeList can show data only from the underlying DataTable and does not take into account datasource relations.
                                To show related data in TreeList, use the Dynamic Loading in Unbound Mode or the Dynamic Data Loading in an Events mode.
