jQWidgets jqxGrid groupcolumnrenderer 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 groupcolumnrenderer property is used to set or return a customized renderer for the columns that are grouped and shown in the grouping header. It is possible only if the groupable property is set to “true”. It is of type function and its default value is “null”.

Syntax:

Set the groupcolumnrenderer property:

$('Selector').jqxGrid({ groupcolumnrenderer: null });

Return the groupcolumnrenderer property:

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