Hi DarioCrivelli, thanks for your kind reply.
Have you extended your Data Adapter accordingly?
I've refer to the sample demo adapter and the documentation but not understand

I found a tutorial on NonvisualTable with Command mode from Alessandro, it works quite well for me. Grouping and filtering can be apply since the display can be customize (I have simply tested and works well, should be OK, have to further testing though).

I discovered a thing during testing, where the snapshot will be clear after the web client been idled sometimes (without doing anything, refresh etc.). Do you have any idea on this? Please correct me if I'm wrong. Thanks.
