There more than 5000 records are displayed in dhtmlxGrid .
To increase 5000 rows loading performance better to use smart rendering mode with dinamically loading. You can test it here dhtmlx.com/docs/products/dhtmlxG … 6158424000
If you want show some pop up dialogs better to wait until loading is over. To detect when loading is done you can use “onXLE” event (at PRO version only):
alert(“loading is over”);
