But this is not returing json inturn.. I want a method to query jsonStore (which may around 1000 records), after quering it should return result which should be again json data (say around 10 records)..
Please let me know am I following correct procedure and is there a method / way to solve this..
Performance issue for Large set data in JSON Store
Ok.. Let me explain the exact issue.
My records in database is more than 60,000.. Data transfer over network is not a problem, but ExtJs is taking much time to load it in store and eventhough I go for paging in grid / combo, its not getting loaded and server call breaks and browser hangs/crashes..
At first, I though of loading entire data (60,000) in grid and do filtering over there.. But its doesn't worked out and if I go for records around 5000, there was not issue..
Then I removed the store mapping in Grid and did only jsonStore load
