如何在Kendo网格中启用或禁用滚动条？

这是我创建网格的代码:

@{
    if (Model.GenericEntityList.Count > 0)
    {
        @(Html.Kendo().Grid(Model.GenericEntityList).Name(screenNames.ToString()).Columns(
              columns =>
                  {
                      columns.Bound(a => a.ID).Title("").ClientTemplate(" a.Name).Title(screen.ToString() + " Name").Width(93);
                  }
              ).Selectable().Scrollable().DataSource(
                  datasource =>
                  datasource.Ajax().Read(read => read.Action("CompSetHide", "Compset"))
              ).Events(a => a.Change("rowclick")
              )
              .HtmlAttributes(new {style = "height: 185px;"}) 
              )
    }
}

如何禁用和启用自动出现在kendo网格内的垂直滚动条？
