Grid – Swap rows Posts

February 19, 2014 at 10:21 pm Grid – Swap rows #49790

Participant

Hi,
I am new to jqxGrid and I’m trying to swap rows when the user clicks the button. Here is the code I have so far but it only updates row 9 and not 10. Can someone please tell me what I’m doing wrong here?

$(“#swapButton”).click(function ()
{
var row1 = $(“#jqxgrid”).jqxGrid(‘getrowdata’, 9);
var row2 = $(“#jqxgrid”).jqxGrid(‘getrowdata’, 10);
$(“#jqxgrid”).jqxGrid(‘updaterow’, 9, row2);
$(“#jqxgrid”).jqxGrid(‘updaterow’, 10, row1);
});

Thanks,
Tony
