javascript - 隐藏/显示剑道网格​​滚动条

Question

我只想在必要时显示我的剑道网格的滚动条。这是我的网格初始化:

@(Html.Kendo().Grid<UT.Repo.Core.up_HedgedCustomerLatestTradeListGet_Result>()
    .Name("lastPositionsGrid")
    .Columns(columns =>
    {
        columns.Bound(c => c.ACCOUNT).Title("Hesap").Width(70);
        columns.Bound(c => c.TICKET).Title("Emir");
        columns.Bound(c => c.SIDE).Title("Yön").Width(50);
        columns.Bound(c => c.STATE).Title("Durum").Width(65);
        columns.Bound(c => c.SYMBOL).Title("Sembol");
        columns.Bound(c => c.VOLUME).Title("Hacim").Width(65);
        columns.Bound(c => c.OPENPX).Title("Açılış");
        columns.Bound(c => c.CLOSEPX).Title("Kapanış");
        columns.Bound(c => c.P_L).Title("Kar Zarar").Width(75);
        columns.Bound(c => c.SL).Title("Zararı Durdur");
        columns.Bound(c => c.TP).Title("Karı Al");
        columns.Bound(c => c.TIME).Title("Zaman").ClientTemplate("#= kendo.toString(TIME, \"dd/MM/yyyy HH:mm:ss\") #").Width(160);
    })
    .Scrollable()
    .Sortable()
    .Resizable(resize => resize.Columns(true))
    .Events(events => events.DataBound("onLastPositionsGridDataBound"))
    .DataSource(dataSource => dataSource
        .Ajax()
        .Sort(sort => sort.Add("TIME").Descending())
        .Read(read => read.Action("HedgedCustomerLatestTradeListGet", "Home"))
    )
)

在数据绑定(bind)上，我试图设置滚动条的可见性:

function onLastPositionsGridDataBound(e) {
    var gridHeight = $("#lastPositionsGrid").outerHeight();
    var gridHeaderHeight = $("#lastPositionsGrid table:eq(0)").outerHeight();
    var gridBodyHeight = $("#lastPositionsGrid table:eq(1)").outerHeight();
    if (gridHeight < gridHeaderHeight + gridBodyHeight) { // show the scrollbar
        $("#lastPositionsGrid .k-grid-header").css('padding', '');
        $("#lastPositionsGrid .k-grid-header").css('padding-right', '17px');
        $("#lastPositionsGrid .k-grid-content").css('overflow-y','scroll');
    }
    else { // hide the scrollbar
        $("#lastPositionsGrid .k-grid-header").css('padding','0 !important');
        $("#lastPositionsGrid .k-grid-content").css('overflow-y', 'visible');
    }
}

隐藏滚动条的部分可以很好地工作，但显示滚动条的部分却不行。这是显示滚动条后的屏幕截图:

如您所见，这些行将标题中的单元格分开，并且行不适合。我该如何解决？

这会起作用，总是尝试自动溢出。

function onLastPositionsGridDataBound(e) {
    var gridHeight = $("#lastPositionsGrid").outerHeight();
    var gridHeaderHeight = $("#lastPositionsGrid table:eq(0)").outerHeight();
    var gridBodyHeight = $("#lastPositionsGrid table:eq(1)").outerHeight();
    if (gridHeight < gridHeaderHeight + gridBodyHeight) { // show the scrollbar
        $("#lastPositionsGrid .k-grid-header").css('padding', '');
        $("#lastPositionsGrid .k-grid-header").css('padding-right', '17px');
        $("#lastPositionsGrid .k-grid-content").css('overflow-y','auto');
    }
    else { // hide the scrollbar
        $("#lastPositionsGrid .k-grid-header").css('padding','0 !important');
        $("#lastPositionsGrid .k-grid-content").css('overflow-y', 'auto');
    }
}
