Ext js 5.1 tutorial, ExtJS GridPanel example getting start, pagingmemory in ExtJS 5.1, read method

When you migrate from ExtJS 4 to 5 then you will find out that lot of things in GridPanel has been changed. If you have implemented "pagingmemor" in ExtJS 4.x then it will not work in ExtJS 5.1, cause's read method has been changed, earlier there were three arguments were passed and this time only one 'operation' is there. Due to absence of 'scope' and 'callback' your '' will not work and this is important JS for local memory sorting, filtering and pagination.

ExtJS 5.1 came up with new configruation in '' and that is '' .
You do not need to do any thing for local memory pagination, just set this configuration true. That is.

Below is the full example of this configuration:
