Answer: 
Take a look at the [Filter menu customization](http://demos.kendoui.com/web/grid/filter-menu-customization.html) demo. It appears you would do something along these lines:

```
@(Html.Kendo()
      .Grid<MyClass>()
      .Name("grid")
      .DataSource(data =>
                  data.Ajax()
                      .ServerOperation(false)
                      .Read(read =>
                            read.Action("MyAction", "MyController"))
      )
      .Columns(cols =>
          {
              cols.Bound(x => x.dt).Title("Date").Width(150);
              cols.Bound(x => x.name).Title("Name").Width(250);
          })
        .Filterable(filterable => filterable
            .Extra(false)
            .Operators(ops => ops
                .ForString(str => str.Clear()
                    .Contains("Contains")
                    .StartsWith("Starts with")
                    // any other filters you want in there
                    )))
      .Sortable())

```

If I'm interpreting it correctly, the `str.Clear()` clears out the filters that exist so you'll be building your own from there. So if you don't think the client needs or wants the `.EndsWith` filter, for example, you would not include it here.
If you have source code open kendo solution and find 
class name `StringOperators` under `Kendo.Mvc/UI/Grid/Settings`

In `Operators = new Dictionary<string, string>()` 
change the order as you wish , reBuild the solution and then overwrite generated file in your project.
