    I would like to conditionally disable custom command button when a specific value existing in a column field.

                    .Events(e => e.DataBound("commandButtons"))
                    .Columns(columns =>
                        columns.Bound(c => c.Customer).Title("Customer");
                        columns.Bound(c => c.CustomerID).Title("Customer #").Sortable(false).Width(100);
                        columns.Bound(c => c.EquipmentID).Title("Equipment #").Sortable(false).Width(100);
                        columns.Bound(c => c.AlarmCode).Title("Alarm").Sortable(false).Width(75);
                        columns.Bound(c => c.AltAlarmDescription).Title("Description").Sortable(false);
                        columns.Bound(c => c.FirstAlarmDateLocal).Title("Alarm Date").Format("{0:MM/dd/yy hh:mm:ss tt}").Width(175);
                        columns.Bound(c => c.AlarmCount).Title("Count").Sortable(false).Width(75);
                        columns.Bound(c => c.AssignedTo).Title("Assigned To").Sortable(false).Width(175);
                        columns.Command(command => command.Custom("Assign").Click("assignAlarm")).Width(100);
                        columns.Command(command => command.Custom("Auto Case").Click("showResolveWindow")).Width(100);
                        columns.Command(command => command.Custom("Manual Case").Click("createSfdcAlarmCase")).Width(100);

     When c.AssignedTo == "" I would like to disable the Auto Case and Manual Case buttons.  It is not clear to me how to accomplish this with a custom command.

    Hello Jim,

    There is no configuration option for disabling custom commands. A visually disabled style could be applied in the dataBound event handler of the Grid by iterating it's items.

    columns.Command(c => c.Custom("customCommand"));

    .Events(e => e.DataBound("dataBound"))

    function dataBound(e) {
        var grid = this;
        grid.tbody.find("tr[role='row']").each(function () {
            var model = grid.dataItem(this);
            if (model.Freight > 20) {

    Nevertheless this will not prevent the custom handler for the command to be executed. You should perform similar check in the command click handler.
