Tag Helper - Model Validation Attributes not rendered

[Daniel]

Hey guys,

I think it is a bug because the requried validation attribute is not rendered when using tag helper. Can you validate my problem?
Kendo version: 2022.1.119

Model:

[Required(ErrorMessage = "Hey, I am an error message.")]
public string Test { get; set; }

View (working example with html helper):

@Html.Kendo().TextAreaFor(x => x.Test).Rows(3)

View (not working example with tag helper):

<kendo-textarea name="Test" rows="3"></kendo-textarea>

 

The data-val="true" data-val-required="xxx" attributes are only rendered with html helper.

Hi Daniel,

Upon investigation I see the `for` configuration is not actually implemented for the TextArea TagHelper. Currently the model attributes are not rendered as the TextArea is not bound to the model property. I have logged a request on the functionality on your behalf, so the following will become available and the TextArea can be bound to a model"

<kendo-textarea for="@Model.Test" rows="3"></kendo-textarea>

Until the above request is implemented you can either use the HTML Helper, add the validation attributes manually, or use a TextBox or an Editor component, where the `for` tag is exposed:

<kendo-textbox for="@Model.Test"></kendo-textbox>
<kendo-editor for="@Model.Description"></kendo-editor>

Finally, I have updated your Telerik points, as this is indeed a valid request.
