jQWidgets jqxTreeGrid rowSelect Event

Read

Discuss

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 rowSelect event is triggered when a row of the specified jqxTreeGrid is selected.

Syntax:

$('#treeGrid').on('rowSelect',  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;
});
