Currently, if a DATASET has a RECURSIVE relation and its TEMP-TABLES are filled with FILL, using that DATASET as the Handle of a BindingSource permits to automatically show the data in a hierarchical way in the UltraGrid linked to the BindingSource. However, if, e.g., the FILL occurs on an AppServer or if the TEMP-TABLEs are filled "manually", the UltraGrid displays the data as flat (non hierarchical) data. There is currently no way to activate that hierarchical relation outside of a FILL, even tough, at the end, it is exactly the same data in the TEMP-TABLEs of the DATASET. The idea is to provide such a way (maybe doing the "under the hood" work on the first SYNCHRONIZE of the relevant TEMP-TABLEs?). From a developer in case 00326362: "The recursive support in the BindingSource is tightly integrated with the DataSet's Fill() method, so in order to display a DataSet that has a Recursive Data-Relation using the BindingSource, you do need to use the Fill() method."
