When you see the Cuike519's PowerDataGrid (original address: http://www.foxhis.com/powermjtest/), it feels very good, but there will be more or less problems during the application of actual projects. For example, it does not support data sources (it is not possible to write in SQL, which is not conducive to packaging business), Oracle 9i database supports problem (we need to develop in Oracle), it is not very good. Later, carefully studied that some of the problems of the control were discussed with Cuike519, and some BUG was modified. Now release the latest PowerDataGrid, I hope to help you.
