Extjs Combobox using json

Question

What is the max size for combobox using json? I seem to die at 5000 json elements.

Answer 1

To state the obvious, from a usability standpoint rendering thousands of records into any UI component is completely useless. No human will be able to make use of that much data. A better approach would be server-side filtering to fetch a usable subset of the data. The combo also supports remote paging if that's an option for you -- there's an example of that in the Ext samples. There's no "built-in" limit to the amount of data that the combo can handle, but there are practical limits to how much data/rendering any page can handle and still be responsive.
