[Adem]

Can I give  a AutoComplete object to a dropdownlist's CascadeFrom parameter? I have tried it  but it didn't work.(two dropdownlist worked fine)


public JsonResult GetCustomers()
        {
            return Json(CustomerRepository.Repository.Customers, JsonRequestBehavior.AllowGet);
        }

        public JsonResult GetVendors(int customerId,int customerId2)
        {
            return Json(VendorRepository.Repository.GetVendorsByCustomer(customerId), JsonRequestBehavior.AllowGet);
        }


function filterVendors() {
    return {
        customerId: $("#CustomerId").data("kendoAutoComplete").value(),
        customerId2: $("#CustomerId").data("kendoAutoComplete").value(),

    };
}

function filterProducts() {
    return {
        vendorId: $("#VendorId").data("kendoDropDownList").value()
    };
}


<dl>
    <dt>
        @Html.LabelFor(m => m.CustomerId):
    </dt>
    <dd>

        @(Html.Kendo().AutoCompleteFor(m => m.CustomerId).Name("CustomerId")
              .ValuePrimitive(true)
                      .DataTextField("CustomerId")
              .DataSource(dataSource =>
              {
                  dataSource.Read(read => read.Action("GetCustomers", "Home"))
                            .ServerFiltering(true);
              })
        )
        @Html.ValidationMessageFor(m => m.CustomerId)
    </dd>
</dl>
<dl>
    <dt>
        @Html.LabelFor(m => m.VendorId):
    </dt>
    <dd>
        @(Html.Kendo().DropDownListFor(m => m.VendorId)
              .AutoBind(false)
              .ValuePrimitive(true)
              .OptionLabel("Select Vendor...")
              .DataTextField("VendorName")
              .DataValueField("VendorId")
              .DataSource(dataSource =>
              {
                  dataSource.Read(read => read.Action("GetVendors", "Home").Data("filterVendors"))
                            .ServerFiltering(true);
              })
              .CascadeFrom("CustomerId")
        )
        @Html.ValidationMessageFor(m => m.VendorId)
    </dd>
</dl>

Hello Jale,

I am afraid that such functionality is not supported and if you need something like this, you need to use the widget events to manually implement the cascading functionality. Please check the following documentation articles that might be helpful:
