extjs 5.1.0 pagingmemory example extjs 5.1.0 pagingmemory alternative Ext JS GridPanel, sorting, filtering, pagination on local data

 pagingmemory config was working very fine till Ext JS 4 BUT it seems some issue is there in Ext JS 5. So we can not use pagingmemory directly, in stead we have to manually handle data from pagination. It is easy and just one line code, take page start and limit value and slice your actual data and send back to store proxy data variable.

Two thinks  keep in mind for below example:
1. In storeProxy, added new config name is actualData where you have to assign your complete data fetch from back end.

2. storeProxy.reader.rootProperty value I used in manually hardword "rows" in slice method where I cut data for current page.

Please just copy and paste below code (change extjs css and js file path accordginly), it work perfectly.
