We are interested in the Dynamic Loading capabilities of the control.

a. Can it be configured to have a sliding window of buffered data?  The demo appears to incrementally download more data as the user scrolls down.  What if the record set is huge (2,000,000) and for memory or whatever reasons on the client we don’t want to cache that much data?  Can it control the virtual data viewport on the actual data set?

b. How much control (custom or otherwise) is available to display status as data is being fetched (i.e. either inline with text like “loading…” or icons, cursors, etc.)?

a)New edition of dynamical scrolling (called Smart Rendering) appeared in version 1.1 – Idea is the following – only rows which should be shown do user will be rendered (or, if you use dynamical loading, - only rows which should be shown do user will be loaded from server). Thus you can scroll to the very bottom of the grid and see last rows. The only strong requirement – you have to specify how many rows are in dataset.

b) You can use event handlers (onLoadingStart and onLoadingEnd) to show any progressbar or message you need while data is loaded from server.

If you haven't found the needed information there and still looking for a solution, you will find the additional help checking javascript framework ajax and filter table javascript.
