View Full Version : Grid with lazily loaded expandable detail

12 Feb 2013, 8:06 AM
I have a grid that will have a custom renderer to have an expandable section to show some related info (detail tables). But I would like to lazy load this detail for performance reasons and because my backing RDBMS doesn't support cross-tab queries.

I see the rowexpander user extension but as far as i can tell, that supports row expansion only if the data is in the store already. Maybe I am misunderstanding it? Anyway, I REALLY don't want to preload this data. What are my options?

You can add an expandbody listener to the rowexpander and then load your data when the row is expanded and add the detail to the expanded row body.
