'DevExpress Pass two keys to LookupFor DataSource request on LoadUrl

I Have two column for key in table but I cant find any way to pass them both...

This is my element

<div class="form-inline">
        @Html.LabelFor(m => m.StreetCode)
        <div class="form-inline formGroup">
            @(Html.DevExtreme().LookupFor(m => m.StreetCode).ID("StreetCodeId")
                                                   .DataSource(d => d.RemoteController()
                                                   .LoadUrl("/look/Streets")
                                                   .Key("CodeStreet"))
                                                   .ValueExpr("CodeStreet")
                                                   .DisplayExpr("Street")
                                                   .Width("100%")
                                                   .Value(Model.StreetCode))
            <span asp-validation-for="StreetCode" class="text-danger"></span>
        </div>
    </div>

this is my method

   public IActionResult Streets(DataSourceLoadOptions loadOptions)
    {
        return Json(DataSourceLoader.Load(DB.Table, loadOptions));      
    }

When I execute it I get enter image description here

I get the right key for street

When I try to pass two keys I got

like .Key("CodeStreet","CityCode"))

for example

<div class="form-inline">
        @Html.LabelFor(m => m.StreetCode)
        <div class="form-inline formGroup">
            @(Html.DevExtreme().LookupFor(m => m.StreetCode).ID("StreetCodeId")
                                                   .DataSource(d => d.RemoteController()
                                                   .LoadUrl("/look/Streets")
                                                   .Key("CodeStreet","CityCode"))
                                                   .ValueExpr("CodeStreet")
                                                   .DisplayExpr("Street")
                                                   .Width("100%")
                                                   .Value(Model.StreetCode))
            <span asp-validation-for="StreetCode" class="text-danger"></span>
        </div>
    </div>

DevExpress does not support composite keys to my knowledge. Take a look at this thread.

You can also override the onLoad and pass the keys through a URL parameter.
