jQWidgets is a JavaScript framework for making web-based applications for PC and mobile devices. It is a very powerful, optimized, platform-independent, and widely supported framework. The jqxGrid is used to illustrate a jQuery widget that shows data in tabular form. Moreover, it renders full support for connecting with data, as well as paging, grouping, sorting, filtering, and editing.

Syntax:

  • Set the initrowdetails property:
$('Selector').jqxGrid({ initrowdetails: null });

var initrowdetails = $('Selector').jqxGrid('initrowdetails');
