We have been able to replicate a serious grid issue.

If you use a ISDataSource, it is NOT able to work with the grid. It will cause other users to see each others data or break the grid.

We have turned off data caching in ISDataSource. We also turned off caching in the Grid. If 2 different people are browsing the site (using Paging), when you page to a another page, you will see what a different user is seeing! In addition, it also then breaks the grid and causes it to only show 1 of 1 page, even though there are 1 of 9.
