剑道网格过滤器菜单

我想将网格的filtermenu配置为使用"contains"作为默认过滤器选项。

这是我的设置。但这并没有改变deafult filter选项（额外的选项按预期工作）！

.Filterable(filter =>
 {
     filter.Extra(false);
     filter.Operators(op =>
     {
         op.ForString(str =>
         {
             str.Clear();
             str.Contains("Contains");
         });
     });
 })

完整视图：

@{
    ViewBag.Title = GlobalResources.EmploymentStatus;
    Layout = "~/Views/Shared/_Layout.cshtml";
}
