jQWidgets jqxGrid ready Property

Last Updated : 29 Mar, 2023

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.

The ready property is a callback function that is invoked whenever the displayed jqxGrid is loaded as well as the binding of the grid is finished. It is of function type and its default value is null.

Syntax:

  • Set the ready property:
$('Selector').jqxGrid({ ready: null });
  • Return the ready property:
var ready = $('Selector').jqxGrid('ready');
