jQWidgets jqxTreeGrid rowClick 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 rowClick event is used to trigger when a row of the specified jqxTreeGrid is clicked.

Syntax:

$('#treeGrid').on('rowClick',  function (event)
{
// Arguments of the event
var args = event.args;
// Data of the row
var row = args.row;
// Key of the row
var key = args.key;
// Data field or column name
var dataField = args.dataField;
// The double click event
var clickEvent = args.originalEvent;
});
