How to clear Ext JS store without affecting/deleting records in the server

I have a Ext JS grid store with autosave set to false.

I want to clear ONLY the local store, without affecting/deleting records in the server.

If I try store.removeAll(), then when the next store write occurs, all records are deleted.

How to call store.removeAll with clearing all pending changes after it?

The removeAll has a silent parameter that can be used to clear records rather than delete from the server:

http://docs.sencha.com/extjs/3.4.0/#!/api/Ext.data.Store-method-removeAll

gridPanel.store.removeAll(true);

From the code comments:

    if (silent !== true) {  // <-- prevents write-actions when we just want to clear a store.
        this.fireEvent('clear', this, items);
    }

If you then manually want to update a GridPanel to clear all rows you need to call:

gridPanel.view.refresh();

For ExtJS 4.1, this will clear buffer cache (prefetched data), so the next time you load (or loadPage), store will reload the pages from scratch:

store.pageMap.clear();

which was previously done as:

store.prefetchData.clear();

Store.loadData([],false);

This statement drop local cache and not send changes to server side

Ok, from what I understand you want to ignore changes to the local store and not send it to the server side. Have you tried using:

myStore.rejectChanges();

This method clears all outstanding changes on all modified records. This will reject all pending changes.
