I have a Grid that is linked to an ArrayStore, both are in the page script. The ArrayStore is filled with data during page generation. The Grid is enabled to edit fields, one at a time. After the edit, the Grid persists the changes and the whole ArrayStore is sent to server via AJAX (I have configured a proxy in it). All works. However, there are two problems that I am facing with it:
1) Although the Grid displays the newly entered value, the ArrayStore data does not change. As a consequence, what is sent to server with AJAX is the same data as the page was generated with, without any changes. How do I commit the changes from the Grid to the ArrayStore???
2) Upon synching, the whole table is sent. I want to avoid it by only sending the rows that have changed. How can I do that?
I have found some scarce examples of these topics but I cannot figure out a clear view of the matter...
