If your total record count is too high (e.g. 25K or so), then showing all on a page will make browser freeze. It’s not datagrid issue but a browser rendering issue. If you tell reason why you want to show 25,000 rows on page i can suggest some better solution.

You can also use lazy loading feature and it will load next page when you scroll at end of page. Set following in grid_options.

$opt[“scroll”] = true;

This page is loading after some time but 2000 records also not loading that\\\\\\\\\\\\\\\’s what the problem is
