    Hey,
    My Code:

    $(document).on(“rowUncheck”, “#divEmployeeTreeGrid”, function (event) {
    debugger
    var args = event.args;
    var row = args.row;
    uncheck(a);
    serchCriteriaEmployeeTreeArray.pop(row.EmployeeCode);
    });
    function uncheck(a) {
    debugger
    for (var i = 0; i < a.length; i++) {
    $(“#divEmployeeTreeGrid”).jqxTreeGrid(‘uncheckRow’, a[i].EmployeeCode);
    }

    }

    problem:

    When First time uncheck function is call its uncheck but after that this event will call $(document).on(“rowUncheck”, “#divEmployeeTreeGrid”, function (event) and again uncheck function will call and a[i].EmployeeCode will remain same so uncheck will work only one time so parent and its only 1st child wil uncheck and uncheck will not work properly.

    please suggest what should i do for uncheck by existing array.

    Hello Alien,

    You should never call uncheckRow within rowUncheck event handler. This leads obviously to loop because uncheckRow method raises rowUncheck event.

    Hello Alien k,

    I don’t know what you want to do. Calling methods and setting properties depends on you app’s logic. I am just telling you that you shouldn’t call uncheckRow method within rowUncheck event handler because you’ll go into infinite loop i.e A calls B and B calls A and this never ends.

    Hi Alien,

    There’s no built in mechanism. Add some IF’s and Boolean Flags in the event handler and only on certain conditions depending on your app, call uncheckRow.
