How to retrieve JSON Data Array from ExtJS Store

Question

Is there a method allowing me to return my stored data in an ExtJS Grid Panel exactly the way I loaded it using:

var data = ["value1", "value2"]
Store.loadData(data);

I would like to have a user option to reload the Grid, but changes to the store need to be taken into account. The user can make changes and the grid is dynamically updated, but if I reload the grid, the data that was originally loaded is shown even though the database has been updated with the new changes. I would prefer not to reload the page and just let them reload the grid data itself with the newly changed store.

I guess I'm looking for something like this:

var data = Store.getData();
//data = ["value1", "value2"]

after its all said and done. Or is there a different way to refresh the grid with new data that I am not aware of. Even using the proxy still uses the "original" data, not the new store.

Answer 1

Store.getRange() seems to be exactly what you are searching for. It will return you Ext.data.Record[] - array of records. If no arguments is passed, all the records are returned.
