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 jqxDataTable is used for reading and displaying the data from the HTML Table. This is also used to display data from various data sources like XML, JSON, Array, CSV, or TSV.

The rowCollapse event is activated whenever a row of the displayed jqxDataTable is collapsed.

Syntax:

$('Selector').on("rowCollapse", function (event) {
  // Code
});
