There was a so called paging memory proxy (PMP) ‘Ext.ux.data.PagingMemoryProxy’ for 4-th and 5-th versions of ExtJS. PMP was merged in later versions but till now developers are looking for it by the upgrade of their applications to the 6-th version.
Filter paging toolbar will help users to filter the rows of grid. Users can select as target all or some of columns. It works with remote and local filtering. The code is pushed into one class (extension of the paging toolbar) to make the usage easier.
