Inline Grid Editor, DropDown Validation Not Visible

I have a Kendo Grid with an editor on a fk field, the class had the following attribute on a drugID field:
[Required(ErrorMessage = "Drug is required")]

However, the validation message was not appearing.
Originally the editor template for this field was as follows:

@using Kendo.Mvc.UI

@*@model IQueryable<Model.Models.Drug>*@

@{

    Layout = null;

}

 

@(Html.Kendo().DropDownList()

.DataSource(source =>

{

    source.Read(read =>

        {

            read.Action("GetDrugs", "PHMedications");

        });

})

.DataTextField("drugName")

.DataValueField("drugID")

.Name("drugID")

.OptionLabel("- Please select -")

 .HtmlAttributes(new { data_value_primitive = true})

)

 

Telerik Support sent me the following information which resolved my issue:

Please try with the DropDownListFor helper instead of DropDownList with a Name:

Copy code

@model drugIDType

 

@(Html.Kendo().DropDownListFor(model => model)

    .DataSource(source =>

    {

        source.Read(read =>

            {

                read.Action("GetDrugs", "PHMedications");

            });

    })

    .DataTextField("drugName")

    .DataValueField("drugID")

    .OptionLabel("- Please select -")

    .HtmlAttributes(new { data_value_primitive = true})

)

The editor templates are created in the context of the property and will have a prefix the property name. Thus the field that will be used to find the attributes when setting a name will be "PropertyName.PropertyName" and no attributes will be found.
