Scrolling large OnDemand grids

[scbird]

There appears to be an issue with OnDemand grids that have many rows. It is impossible (or at least extremely difficult) to scroll to the bottom of them - when dragging it, the scroll bar doesn't correctly follow the mouse. It appears that the height of the grid (or at least the scrolled area) does not correctly reflect the total number of rows returned by the store, and that it is being expanded as you scroll down.

This can be seen in dgrid/test/performance.html - you cannot scroll properly to the last row. This problem doesn't occur in the equivalent page for dojox.Grid.

This is unfortunately due to how the OnDemandList module is presently designed. It's something I'll be sure to bring up in discussion again, but for the time being, you should be able to mitigate this behavior to a degree by playing with the maxEmptySpace property in the arguments passed to the constructor. (It defaults to 10,000 px.)

Whoops, didn't realize this was still hanging open; this has been resolved by #132 (which includes #117).

Actually it may still be open - I think there are still issues in #132 (which are resolved by the two last commits in #117, which I'm pretty sure weren't included in #132), but I haven't had time to check it yet. If the issues still exist I'll reopen this ticket.

OK, thanks. I was initially under the impression those had been resolved based on Kris' response, but by all means, let us know if you still see issues. Thanks for your contributions!
