We have an application with about 2200 rows in a grid. When the grid first shows, it is fine, and the browser log shows that the first 200 rows were retrieved from the server.
When I start scrolling down, eventually some rows are not displayed. The browser log shows that all the remaining rows in the grid were retrieved from the server in one http call. Most of the time, the missing rows are at the bottom of the window frame. When rows start to go missing at the bottom, then continuing to scroll down makes more and more rows disappear, until eventually, no rows are displayed. Scrolling back up and then down again sometimes restores missing rows. But not always.
Other times rows are missing in the middle of the list. Our user made a short video showing this case: drive.google.com/file/d/0BxkaZ- … 0zQUU/view
We are using DHTMLX Suite 4.0.2 Pro.
Have you seen this problem before? Any ideas on how to solve it?
