    Question Best way to auto load more data into a grid

    Best way to auto load more data into a grid


    Hi!

    I have been playing with the idea to get data auto loaded into a grid when the user scrolls towards the bottom. I added a listener for scrollevents on the grid and could load more data into it, but:

    1) I cannot append data to the grid, only load data again with N more rows. Is there a append feature i have not seen?

    2) When the data is loaded, it auto-scrolls back to the top, which again triggers the scroll-event. How can i keep the user at the location he/she was at? It feels a bit hacky to save location before loading more data and it wont work well since a mouse scroll will trigger the listener many times before new data is loaded.

    Is there something better to use, perhaps liveGrid?

    I don't have docs for Ext JS 2 but in Ext JS 3, in the load method you can pass a config object and one of the configs is 'add' which if set to true it will append the data instead of replacing the current dataset.

    Thanks for the suggestion!

    I did a test with LiveGrid and it works just as i want to, and it gives me the wanted features without giving the issue with the browser jumping back to the top of the grid.
