Bug report

Link do not appear properly in a TagHelper menu that uses asp-action and asp-controller. In version 2.1 the application crashes

Reproduction of the problem

1. In app that uses Telerik UI for ASP .NET Core 2022.2.510 or configure a TagHelper Menu with the following TagHelpers:

       <menu-item text="Furniture">
             <sub-items>
                 <menu-item text="Tables & Chairs" asp-action="About" asp-controller="Home" ></menu-item>
              </sub-items>
       </menu-item>

2. Run the project

Expected/desired behavior

Microsoft Tag Helpers should create a working anchor tag

Environment

• Kendo UI version: 2022.2.510

Bug report

The TextBox TagHelper does not render the maxlength and placeholder attributes when set via data annotations.

Reproduction of the problem

For a model property defined the following way

[Display(Name = "Example", Prompt = "Example Prompt")]
[StringLength(maximumLength : 5, MinimumLength = 1, ErrorMessage = "Must be between 1 and 5")]
public string Example { get ; set ; }

the TextBox TagHelper generetes

<input
  class="form-control k-input-inner"
  data-val="true"
  data-val-length="Must be between 1 and 5"
  data-val-length-max="5"
  data-val-length-min="1"
  id="Example"
  name="Example"
  value=""
  data-role="textbox"
  style="width: 100%;"
  aria-disabled="false"
  autocomplete="off"
  aria-invalid="true"
  aria-describedby="Example_validationMessage">

when the default ASP.NET Core TagHelper generates markup containing the maxlength and placeholder attributes:

<input
  class="form-control k-invalid"
  type="text"
  data-val="true"
  data-val-length="Must be between 1 and 5"
  data-val-length-max="5"
  data-val-length-min="1"
  id="Example"
  maxlength="5"
  name="Example"
  placeholder="Example Prompt"
  value=""
  aria-invalid="true"
  aria-describedby="Example_validationMessage">

Expected/desired behavior

The maxlength and placeholder attributes are set to the generated input element.

Environment

• Kendo UI version: 2022.2.510
• Browser: [all]

Bug report

When using the TaxtBoxFor HTML helper and the MaxLength is set via DataAnnotation the maxlength attribute is not rendered.

Reproduction of the problem

Model:

public class MyModel
{
    [MaxLength(5)]
    public string Text { get; set; }
}

View:

@Html.Kendo().TextBoxFor(m => m.Text)

Current behavior

The Telerik UI for ASP.NET Core HTML Helper renders the following markup, without the maxlength attribute:

<span class="k-widget k-textbox" style="">
    <input data-val="true" data-val-maxlength="The field Text must be a string or array type with a maximum length of '5'." data-val-maxlength-max="5" id="Text" name="Text" value="" data-role="textbox" aria-disabled="false" class="k-input" autocomplete="off" style="width: 100%;">
</span>

The default Html.TextBoxFor helper renders the following markup, containing the maxlength attribute:

<input data-val="true" data-val-maxlength="The field Text must be a string or array type with a maximum length of '5'." data-val-maxlength-max="5" id="Text" maxlength="5" name="Text" type="text" value="">

Expected/desired behavior

The Telerik UI for ASP.NET Core HTML Helper should render the maxlength attribute.

Feature Request

Create TexBox label from ViewModel Data Annotation

Currently, this is possible using the default @Html.Label, and @Html.Textbox

-Model:

     [DisplayName("First Name :")]

     public string FirstName { get; set; }

-View

        <tr>
         <td>
                @ Html.LabelFor(m=>m.FirstName)
            </td>
            <td>
                @Html.TextBoxFor(m=>m.FirstName)                
            </td>
        </tr>

[Required]
[StringLength(128)]
[DisplayName("Password")]
[DataType(DataType.Password)]
public string UserPassword { get; set; }

<div class="form-group">
  <kendo-textbox name="UserPassword" type="password"> <!-HOW to use DataType Annotation here? -- >
      <textbox-label content="@Html.DisplayNameFor(m=>m.UserPassword)" floating="true" />
   </kendo-textbox>
</div>

The solution below can be used as a workaround for the time being:

@{ Dictionary<string, string> fieldTypes = new Dictionary<string, string>();
    var properties = typeof(TestModel).GetProperties();
    foreach (var property in properties)
    {
        var dataTypeAttributes = property.GetCustomAttributes(
            typeof(System.ComponentModel.DataAnnotations.DataTypeAttribute), false);
        if (dataTypeAttributes.Length > 0)
        {
            var attribute = dataTypeAttributes[0] as
        System.ComponentModel.DataAnnotations.DataTypeAttribute;
            var dataType = (System.ComponentModel.DataAnnotations.DataType)attribute.DataType;
            fieldTypes[property.Name] = dataType.ToString().ToLowerInvariant();
        }
        else
        {
            fieldTypes[property.Name] = null;
        }
    } }
<form id="mainForm" kendo-validator="true">
    <kendo-textbox for="UserPassword" type="@fieldTypes["UserPassword"]">
        <textbox-label content="@Html.DisplayNameFor(m=>m.UserPassword)" floating="true" />
    </kendo-textbox>
</form>
<script>
    $(document).ready(function () {
        var validator = $("#mainForm").data("kendoValidator");
    });
</script
