Grid with Buffered Store. A BufferedStore allows only a small section of a potentially very large server-side dataset to be loaded when required to be displayed, and then discarded when scrolled out of view. Usage of a BufferedStore causes buffered rendering of just the visible range of grid data.

First, we'll modify our store and add a messageProperty attribute to the proxie's reader. This will let us encode some data in JSON on the server and pass anything we want, along with our search results. 2.addAllSelectedPersons / removeAllSelectedPersons does not work properly: there are a lot of fake select/deselect events again (I need to "filter" this events, because for add/remove All I have a special DBcall) and also only buffered records has proper selection, after moving to other page records are without selection.

Grid with Filtered and Buffered Store. A buffered rendered grid with a filtering UI is included which applies a remote filter and reloads the grid beginning at page one. The code is not minified, see filtered-buffered-store.js But the main thing is that you are mixing client-side filtering, server-side filtering, and a buffered store. Client-side filtering can only filter what's in the store at that time, so in a buffered store, you are not performing a search over all records. You would have to look into what ExtJS calls "remote filtering". When store is filtered, finds records only within filter. **IMPORTANT. If this store is Ext.data.BufferedStore, this can ONLY find records which happen to be cached in the page cache. This will be parts of the dataset around the currently visible zone, or recently visited zones if the pages have not yet been purged from the cache.** This causes the buffered renderer to use variableRowHeight: true. The number of rendered rows is only just larger than the visible row count. As the edge of the rendered data scrolls towards being in view, the table has new rows appended just in time, and rows removed from the receding side. The code is not minified, see buffered-store.js
Mar 19, 2014 · In an ExtJS application it is sometimes necessary to reload a store and the challenge is to do it quickly. If the store backs a paged grid the issue doesn't really arise. But if the store backs a grid with many records - and specially if its a tree store backing a tree view - reloading the store efficiently is

The code is not minified, see buffered-store.js Ext JS - API documentation from Sencha On API doc pages there is also a filter input field that filters the member rows using the filter string. In addition to filtering by string you can filter the class members by access level, inheritance, and read only. This is done using the checkboxes at the top of the page. Grid with Buffered Store.

Dec 10, 2015 · Take into account that this sample grid uses remote store (but this will also work with local once). As you can see on lines from 27-29, default filter value has been set to display both statuses ‘online’ and ‘offline’ but you can set either value separately.
