Refresh Data
By design, a tree list control automatically updates itself, if the data is modified in the linked data source. However, in some cases you need to explicitly update the tree list. This may take place when the data source was intentionally locked for notifications to the control, or when the DBMS engine doesn’t provide proper notifications.
For this purpose, invoke the tree list’s FullRefresh method, which will reload the data.
This method is also used if tree list elements are customized via events using external controls. For an example that illustrates the use of the method when external controls are involved in the customization of elements, refer to the ExpressQuantumTreeList Features Demo.
