How to dynamically update summary feature for grid in extjs4.1?
In my application the grid summary will become filled at the time of loading the page, the grid by calculating a total using the summary feature. I have a combo box drop down in the screen. If a user selects from the combo box, I need to update the grid records from store and also need to update the calculated summary value using records coming from another store.
Can anybody tell me how to do that? Thanks
