I am trying to change the Refresh button handler of the Extjs GridPanel top-bar paging tool.
PREFACE: I have created two stores for a single grid panel. One remote store fetches records from the DB and then after that loads the data onto the other local store. The reason is that I want local pagination with a lot of data.
PROBLEM: Since the local store has no proxy on clicking the reload button in the grid's top-bar paging tool nothing happens. I need to overload/change the handler of that button to call the remote store to reload.
MORE PROBLEM: I have only the extjs grid panel object on hand. Can't change the definition/code of the Ext.create('grid-panel',{}). Only have access to the output/grid object. the button is visible through this command but can't change any of its properties.
***.***.****.***.****.gridObject.getDockedComponent('toptoolbar').getPagingItems()[10].items
*** is the namespace of the object(cant share that)
QUESTION: Is there any way to tackle this problem or I am doomed?
