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 jqxTreeGrid is used for representing data in a tree-like structure. This widget is useful for displaying multi-column of hierarchical data, data paging, sorting and filtering, data editing, column resizing, fixed columns, conditional formatting, aggregates, and rows selection. These widgets also read and display the data from any type of data sources such as XML, JSON, Array, CSV, or TSV.
The icons property is used for checking whether the icons are displayed or not.
Syntax:
-
For setting the icons property:
$('#treeGrid').jqxTreeGrid({icons: true}); -
For getting the icons property:
var icons = $('#treeGrid').jqxTreeGrid('icons');
