Question:The advantages of using TwhbdeSource and dataset cloning are well defined relative to using TwhbdeGrid and data grid scrolling. Is there an >advantage to using TwhbdeSource when you are not using scrolling grids but the app has multiple tables and queries?

Answer:No scrolling -> no need for cloning. Just set the MaxOpenDataSets = 1 and you will not have any cloning.

If you are using a TwhdbScan component, the TwhbdeSource is required. If you are using a TwhWebAction component and generating your own database output (which is easier when there is no scrolling), then the TwhbdeSource is not required at all.
