Grid mvc with 2 linked dropdown

[pat]

Hi,

I have 2 dropdowns. A drop-down list and society people who work for the company selected. Change of the company, I want a filter for people who work for this company.

@(Html.Kendo().Grid((IEnumerable<EntrepriseViewModel>)ViewBag.Data)

    .Name("Grid")

    .Columns(columns =>

    {

        columns.Bound(p => p.Id).Visible(false);

        columns.ForeignKey(p => p.IdCompany, (System.Collections.IEnumerable)ViewBag.CompanyList, "IdCompany", "CompanyName").HtmlAttributes(new { id = "CompanyDdl" });

        columns.ForeignKey(p => p.IdEmploye, (System.Collections.IEnumerable)ViewBag.EmployeList, "IdEmploye", "EmployeName").HtmlAttributes(new { id = "EmployeDdl" });

        columns.Command(command => command.Edit()).Width(200);

    })

    .DataSource(dataSource => dataSource

        .Ajax()

        .Model(model => model.Id(p => p.id))

                        .Read(read => read.Action("Company_JSON_Read", "Home", new { id = Model.id }))

                        .Update(update => update.Action("Company_JSON_Update", "Home"))

  

    )

    .Editable(editable => editable.Mode(GridEditMode.InLine))

    )

IdEmployeList must change after IdCompany change but how ?

Thanks
