Bug report

Validation attributes are not rendered on Kendo editors if ViewData contains same key as the model.

Reproduction of the problem

  ViewData["Title"] = "Home Page"; 
}

@using (Html.BeginForm())
{
  @Html.Kendo().TextBoxFor(model => model.Title)
}

<script>
  $(function () {
    $("form").kendoValidator();
  });
</script>

Current behavior

Validation attributes are not rendered.

Expected/desired behavior

Validation attributes should be rendered on the input element.

I just ran into this in version 2021.2.511, when a grid field would not validate. Mentioning it on the demo page and in the documentation (as this issue is over a year old) might save people a lot of time and frustration.
