jQWidgets jqxGrid cellvaluechanged Event
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 jqxGrid is used to illustrate a jQuery widget that shows data in tabular form. Moreover, it renders full support for connecting with data, as well as paging, grouping, sorting, filtering, and editing.
The cellvaluechanged event is activated whenever the value of a cell of the displayed jqxGrid is changed.
Syntax:
$("#Selector").on('cellvaluechanged', function (event) {
// Arguments of the event
var args = event.args;
// Data field of the column
var datafield = event.args.datafield;
// Bound index of the row
var rowBoundIndex = args.rowindex;
// Value of the new cell
var value = args.newvalue;
// Value of the old cell
var oldvalue = args.oldvalue;
