View Full Version : Incremental loading with GridPanel/JsonStore

11 Feb 2011, 2:19 PM
I've spent some time looking into this but haven't found a solution yet.

Say I have a server dataset of 100,000 rows that I want to display in a grid. For bandwidth reasons, using an incremental loading system would be great - ie ExtJS knows the total count of all objects and only retrieves data from the server the selection of objects currently being displayed.

I've looked at PagingToolbar but this doesn't quite seem to do what I need (I just want a long scrollbar, not have to go through each page manually). Are there any examples of how to do this in ExtJS?

Have a look at the LiveGrid user extension.

Excellent, thanks for pointing me in the right direction. Seems to work well for my case (after a few tweaks to deal with the unusual format of my server calls).

So for my next question - is there something similar for DataView? I'm hoping to do incremental loading of a large number of thumbnail images.

Thanks again!
