    Is there any way to force a script (javascript/jquery) to wait for the Grid sync to complete?

    OR any way to retrieve the grid's model with data so as to perform a last update manually?


    Currently due to timing with the async calls:




    There is data-loss when navigating to another page if it is done too soon after these calls are made.


    I have setup and stepped through the existing event calls for both the grid ( and datasource (

    All around it seems the DataSource .Sync() event is the last one triggered.


    Here is the definition for the Grid:

                                .Columns(c =>
                                    c.Bound(vm => vm.FirstName).Width(120);
                                    c.ForeignKey(vm => vm.LocationNumber, (System.Collections.IEnumerable)ViewData["LocationsList"], "LocationNumber", "Drop_Text").HtmlAttributes(new { onchange = "triggerDropChange(this);" }).Width(100).Hidden(Model.Locations_ColumnInitHidden); 
                                    c.Bound(vm => vm.State).Width(120);
                                    c.Command(command => { command.Destroy(); }).Width(40);
                                    c.Template(@<text></text>);//Blank Column to handle Scrollable variable width so headers do not skew
                                .Scrollable(s => s.Enabled(true).Height("auto"))//Scrollable to control column widths
                                .ToolBar(toolbar =>
                                    toolbar.Template("<div class='col-lg-3'>" +
                                        "<a class='pull-right k-button k-button-icontext k-grid-save-changes' href='javascript:void(0)'><span class='k-icon k-update'></span>Save All</a>" +
                                        "<a class='pull-right k-button k-button-icontext k-grid-add' href='/Wizard/EmployeePayrollRead?EmployeeGrid-mode=insert'><span class='k-icon k-add'></span>Add Row</a>" +
                                .Editable(editable => editable.Mode(GridEditMode.InCell)
                                .DataSource(dataSource => dataSource
                                    .Events(events => events.Error("employeeGrid_error")
                                    .Model(model => model.Id(vm => vm.PolicyHolderPayroll_EmployeeGridId))
                                    .Create("EmployeePayrollCreate", "Wizard")
                                    .Read("EmployeePayrollRead", "Wizard")
                                    .Update("EmployeePayrollUpdate", "Wizard")
                                    .Destroy("EmployeePayrollDestroy", "Wizard")


    With a call to navigate and save:

    <a class='k-button k-button-icontext k-grid-save-changes pull-right' href='javascript:save_Grids_n_Move()'><span class='k-icon k-update'></span>Save All</a>


    function save_Grids_n_Move() {
            var Grid_save = $("#Grid").data().kendoGrid;

        element.closest("form").each(function () {
                        var form = $(this);
                        form.attr("action", action);
