I have following document to implement treelist but there is not data display

Look at my implementation picture below

According to https://demos.telerik.com/aspnet-mvc/grid/editing-custom-validation,I write the following script.  It can be executed in javascript.  But it  has a syntax error when using typescript. The syntax "kendo.ui.validator" doesn't exists. How can I solve this problem and what "kendo.ui.validator" means?

$.extend(true, kendo.ui.validator, {
        rules: {
          required(input) {
            if (input.is("[name='LineNumber']")) {
              if ($.trim($(input).val()) === "") {
                input.attr("data-required-msg", "@ViewLocalizer["LineNumberNullErrorMessage"]");

                return false;
              }
            }

            if (input.is("[name='ParameterName']")) {
              if ($.trim($(input).val()) === "") {
                input.attr("data-required-msg", "@ViewLocalizer["ParameterNameNullErrorMessage"]");

                return false;
              }
            }

            return true;
          }
        }
      });

Anyone know how to go into a Taghelper output, and receive the full HTML markup for Masked TextBox?

The following was not working:

output (only gave some of the html)

output.GetChildContentAsync().GetContent();   (Was Not working !!)

It Should look like this,

            <span class="k-widget k-maskedtextbox" style="">

                <input id = "test" name="test" data-role="maskedtextbox" class="k-textbox" autocomplete="off" style="width: 100%;">
                <span class="k-icon k-i-warning"></span>
             </span>

              <script>kendo.syncReady(function(){jQuery("#test").kendoMaskedTextBox({"rules":{}});});</script>

This is our Taghelper Edit Code,

namespace Test.Web.UI.TagHelpers

{
    [HtmlTargetElement(HtmlTargetElementConts.SearchTextBox)]
    public class TestTextBoxTagHelperGeneral : MaskedTextBoxTagHelper
    {

        [HtmlAttributeName]
        public bool Bold { get; set; }

        [HtmlAttributeName]
        public int? Height { get; set; }

        [HtmlAttributeNotBound]
        public int DefaultHeight { get { return 50; } }

        public IptsTextBoxTagHelperGeneral(IKendoHtmlGenerator generator) : base(generator)
        {
        }

        public override void Process(TagHelperContext context, TagHelperOutput output)
        {
            if (Bold || Height.HasValue)
            {
                if (Height.HasValue)
                    output.Attributes.Add("style", "height:" + Height + "px");
                else
                    output.Attributes.Add("style", "height:" + DefaultHeight + "px");
            }
            Name = "test";
            base.Process(context, output);

How do I Get the Final HTML Markup?
