Ext JS's grid supports buffered rendering, which enables you to load large numbers of records into a grid without paging. Only the visible portions of the loaded store are rendered into the DOM. 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.

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 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. 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.

I can tell you from my own recent experience that if you don’t use the Sencha ExtJS Store load method properly, nothing will happen. After torturing myself twice by mishandling the load method, I thought maybe it would help if I wrote a quick blog post about how to properly use the load method.

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".
