jQWidgets jqxTreeGrid sort Event

  • Last Updated : 07 Oct, 2021

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 sort event is triggered when the sorting order or sorting column of the specified jqxTreeGrid is changed.


$('#treeGrid').on('sort', function (event) {
    var args = event.args;
    // column's data field.
    var sortcolumn = args.sortcolumn;  
    // sort order:
    // { 'ascending': true or false,
    //   'descending': true or false }
    var sortdirection = args.sortdirection;
